In 2015, there was a very pronounced seasonality around the 3rd Friday of the month, where the market would ramp higher going into both quad-witch options expiration, and non-quarterly expiration, and then mean revert lower post expiration. J.P. Morgan had a couple of strategies that provided exposure to such options expiry momentum and it's subsequent mean reversion. Of course, this Friday's August expiration saw the market sell off the day before opex, and close unchanged on Friday. This is very similar to what happened during May opex of this year, when the ES sold off ~3% two days before expiration. While I'm not quite certain what the market will do next week, ES rebounded strongly the week following options expiration back in May.
As Kolanovic explained, the reason a broader selloff did not ensue is that none of the triggers for systematic selling were breached. Momentum stayed positive, bonds rallied and almost totally offset the equity selloff, and vol targeting strategies had already reached leverage caps at higher levels of volatility than those reached on that day. Options positioning going into May 17 was benign and long gamma, and as is often the case, moves are reverted when there is positive gamma exposure.
Bonds are once again negatively correlated to spooz, offsetting falling equity prices, and today's vol levels have only increased commensurate with May 17th's levels, however current VVIX:VIX is substantially higher than back in May, and momentum has turned negative. September options open interest is skewed toward puts in the current trading range with large pins at the 2400 and 2350 levels.
The stuffed cabbage appears to be falling apart, and there is no shortage of potential explanations as to why: trumpeachment, tax reform delay, balance sheet reduction, fed tightening, and if there were to be a selloff this Monday–renewed bellicose dialogue between the Kim and the Donald over war games.
P/C ratios continue to be bearish, and don't show signs of being overbought. A post-expiration move below 2425-20 on Monday would take dealers further short gamma as expired hedges are rolled forward boosting volatility. A test of 2400 in the ES then seems likely where a break below, might not be bought. The 'world' is leaning against that level, and recent statements imply the Fed may not be as inclined to be a buyer, as they have been in the past.
The powers that be seem determined not to allow gold to build value above 1300, however the $/yen is on the precipice, and further domestic conflict would pare it's price and support rallies in gold and treasuries. In any case triple bottoms (usd/jpy) and triple tops (gc) never hold.

I still think we challenge the all-time highs first, and, very possibly, go into another strong up leg this Autumn on the inevitable tax cut legislation. The big bull–from wherever you begin looking at it from, March 09, Nov 2012, or, as I see it from January 2016, is far from over. And that means higher highs before it is.
I can be long and wrong but not short and wrong on the timing of all of this. But I'm quite certain we're going right back up to those all time highs here, just not so sure about tomorrow.
The bull market in bonds takes a breather this week.

This is a paper by Victor Haghani of LTCM fame on bet sizing observing and analysing how people place bets on a coin flip that is biased to come up heads 60% of the time.
Ralph Vince writes:
It's a very interesting paper, and to many might be surprising. A couple of comments:
1. It assumes someone's criterion in wagering on this is to maximize what someone makes. This is certainly not the case in capital markets, where (the rather nebulous) risk-adjusted return is king, specfically: "Optimal F: Calculating the Expected Growth-Optimal Fraction for Discretely-Distributed Outcomes"
2. Even what the authors and Thorp himself claim are the amounts to wager so as to maximize expected gain, their answer is not quite aggressive enough! The amounts the refer to are asymptotic, as the number of trials ever-increases. The author himself points to a horizon of 300 plays in half an hour, and the actual optimal wager (which would, int hat time period, yield a greater return than the authors or Thorp point to) is slightly more aggressive, and can be determined from the above paper.
Not trying to toot my own horn (it needs no tooting, and besides, my horn will do a lot, but tooting it won't do) but the paper is inaccurate on these two points.

Thank you for the interesting article. The other night at our band practice, the bass player's wife, who works at a public school, asked me if I was taking my money out of the market. She had heard a number of people were worried about the election and a market drop if either candidate was elected. I told her the market would probably go up, though it might jump around a bit. I thought that was interesting. Its an example of the public doing the wrong thing, for the wrong reasons. It reflects peoples fear about uncertainty about the election. It helps explain some of the market action recently.

How the stock market will perform over the next 30 or 60 days has very little to do with the study of a coin that is heavily loaded to land on heads. At best, the stock market's performance over the next 30 days is only slightly better than 50:50.

One fact mentioned in the article is "The average vehicle is used only 4% of the time and parked the other 96%."
I guess it is tempting to fix this huge inefficiency, but unfortunately the 4% usage time is not arbitrary, probably 90% of people have concurrent usage time: to commute to/from work.

The issue I find with the Segway is battery life and time to become comfortable using it. I have a Ninebot mini Segway pro; it took two rides to get comfortable with it but I almost returned it after the first.
Navigating uneven roads and curbs are also a challenge. Weather is challenging and it's sufficiently heavy that carrying it on/off bus or train is suboptimal (heavier than a commuter bike.)

My son and I were early adopters of hoverboards (a mini-Segway clone), a year before they got big. These days we don't ride them any more due to safety concerns, and quality issues. But then again, why would one ride a hoverboard, when one can ride a one wheel. My son and I got a couple of them in summer 2015 and haven't looked back. They will go anywhere, on any terrain, fast, dangerously fast. The boards are well made, fly like the wind, and one can even use them at the beach as long as they are not totally submerged. The battery charge lasts longer than one's legs. One Wheel's are seductively dangerous. My go to board that every day I ride around the neighborhood is still the boosted board. Expensive, but worth every penny.

I can visit 4 places in the time it takes to park. It THE way to go. I put some grocery bags on the back. It has tail lights and headlights.

Three tidal waves of the future, breaking simultaneously:
They are highly complementary to each other, empowered by software, and will fundamentally change transportation.
It's a question of when, not if. Will we substantively change in the next decade, or will it take 2 or 3 decades?

Just a minute…
As we all know from trading, if you want to increase your profitability over time the most effective strategy is to limit losses. Possibly related to this is the result of several studies attesting that fear is a greater motivator than greed, buy a factor of 3 to 1. Furthermore, we all look at prices and know both instinctively and historically that those prices will not be constant over time. They may be higher or lower, but not the same. Thus, pessimism is historically justified, profit-saving and possibly life-saving.
But to want to trade these markets for profit, one also has to be optimistic, often excessively so in light of bad experiences. You need both.

Many good reasons for worry exist. If you're not worried, you're not paying attention. All of the worries stem from something completely nobody talks about in polite company: population explosion. In 1804, the world's population was 1 billion. In 2012, it topped 7 billion. It's projected to reach 9 billion in 2042 — within my son's lifetime.
True, Paul Erlich got it wrong when he said we'd all starve by the end of the 1970s– but go back read his book. Then reflect on how much different life is.
All those people are unsettling policymakers, with these results (and they are what's secretly worrying us):
Unspoken Fear #1: War. Today's empire builders are intent on grabbing resources; nuclear weapons are in too many hands.
– China: rich and populous; thanks to the free-trade break we gave them in the 1970s, they've created a war machine and ready to go for our jugular.
– Islam: implacable and populous; we have spent trillions trying to establish a decent government, and the area keeps morphing into an empire that despises us and all we stand for; they want their old empire back, be it from Baghdad or Istanbul.
– North Korea: Our strategy is, "Let's all ignore that man in the corner, and maybe he'll quiet down."
– Russia: ruthless, and intent on restoring the empire of Rus.
Unspoken Fear #2: Dystopia.
– When people don't have honest work, nothing good can come of it. In America alone, 94 million people are out of the work force. We're not being honest about the impact of robots and artificial intelligence. It's this fear that gave Trump the nomination, not that he knows what to do with it.
Unspoken Fear #3: Central government that keeps growing.
– Confronted by the population explosion, the elites have decided that the masses must be controlled and pacified. This political philosophy shows up in the fear of liability for anything fun, in subsidies, in central banking. We see sledgehammer policy-making, from FDR to Obamacare.
– And the educated love it! Calls for authoritarianism are the norm among socialist youth, aging hipsters, authors and "educators" at all levels.
These memes and unspoken but rational fears show up in pop music, with its ugly pounding overamplified brutalist mindlessness; in contemporary academic music, with its screams and jaggedness; in art, with its sneering cynicism; in architecture, with its boxy Stalinist aesthetics.
It shows up in the piggishness of the powerful, with Hillary Clinton the prime example. The rich expect multiple homes in idyllic spots, bodyguards, private jets; the poor suffer in overbuilt, crowded, noisy, polluted cities.

First, human super-cooperation is built on trust. To evolve as a group, a high percentage of that group must be trustworthy for the compounding effect of the prisoners dilemma to work. As the group grows too big, it becomes too easy for a individual to feign cooperation. Hence the need for creative destruction and for power being placed in the smallest sized group necessary. It has always been easy to look at the big groups and see the corruption and assume that they are in control of the long term future. But the truth is they are dinosaurs and will lose out to the small but wise group/ businesses that still operates at the human individual trust one another level and are quite hidden from the spotlight, because of size. But these time and time again raise the tide for all.
Second, personally, it is too easy to dwell on the jerks that simply can ruin it for everyone but that fall into everyone's life. They can ruin many nights even if as a rule I try to avoid them. A single jerk can derail my perspective and keep me up at nights and easily crush my spirits if I let them. I found the best antidote for me is to turn the tables if I start thinking of the jerks and think instead of those in everyone's life that have blessed them with love, grace and patience. I think of my Dad's second wife, caring for a dementia patient at home for 13 years and weeping tears of love on his passing, the coach that helped me, the friend that's always there, etc. I try not to let the jerks own my mind rather than those loving, lovely (my spouse), good and virtuous people in my life. This also goes with those news makers, politicians and on the dole.
I would note that 3 independent events in currencies over the past few days have raised my antennae. First, comments from the Reserve Bank of New Zealand caused a 1% or so spike higher in the NZD. Second, the potential question of the South African FM has caused a 3% plus move weaker in the Rand. Third, the downgrade of a rating's agency outlook of Mexico caused a 1% or spike weaker in the MXN. The same was true of Korea and the KRW a week ago. Granted these currencies are not the most liquid but I think the reactions in both prices and market commentary following them are above normal. Given the compression in volatility cross markets, lack of general fund performance, market participant risk aversion, and upcoming geopolitical and economic events these moves may be a foreshadowing. I recognize that much of this is qualitative and to be tested a bit further.

Here is some anecdotal info on John's NZD post. New Zealand is booming, thriving and growing fast. It's peak ski season and I hear Japanese, Chinese, Italian, French, American, spoken in crowded restaurants and stores. Prices are very high, much higher than exchange rate justifies. Compare the high prices to low prices in Italy and Japan. Real Estate is booming in part due to Chinese purchases. Chinese tourists outnumber all others 10-1 at parks and heli tours. I wonder if now China is exporting inflation after years of exporting deflation with cheap manufacturing. Money seems to be flooding out of China.
I'm down in New Zealand skiing and kiting. This year is a fairly cold year and has had considerable amount of snow. I've noticed this seems to be a harbinger of global patterns. Another anecdote is that 2005 was an outstanding wine vintage. I had a 06 Pinot Noir and it very good. In Burgundy France my vintner friend tells me that 05 was the best in a decade and that 2015 will be the best in more than a decade. I ve tasted the 2015 en Cave and it's absolutely out of the park compared to recent vintages and may the best of this century. Note the global pattern.

What is Life by Erwin Schrodinger must be one of the important books of the 20th century as it was cited by Watson Crick and Rosalind Franklin as their theoretical inspiration to discover DNA. He asks what the basis of life is from a physics and chemistry point of view. Modern physics is based on statistics and the so called laws are only averages based on the law of large numbers. This observation hit me as profound. At smaller numbers randomness rules. As an example when a gas is present at one end of a container at higher concentration it will diffuse as a result of random motion with slightly more atoms going left than right.
We've seen that trends appear in random time series. In real markets the upper bound is infinity and the random tendency would be for prices to move upward with nothing more than random action. This not even considering the innate urge to produce, the need to consume and innovation and progress. Here at near all time highs this is something to consider
Welcome back former student Mr. Mc. And let it be known that whenever I talk in England, I tell the students "don't listen to the triumphal trio as to their conclusions for the future. They suffer from the English disease or the Old Shiller disease. They believe that the dividend model is the sine qua non of the thing that causes returns. And because the dividend yield is not as high now (or in the crazy Shiller instantiation the dividend yield is not as volatile as the stock returns) that the return in the future can't be as high as the past." But .. but. The retention rate varies with possibilities for after service returns, and likely returns on investments and investor preference. If no dividends were paid, the returns would be at least as high, probably higher considering all the opportunities for rent payments from the foundations like those of the cattle trader and the returns from lobbying.

I tend to agree, but as long as every one is admiring the emperor's new clothes it's hard to do otherwise. And the new clothes might be some new technological thing that you'd never think would work, like Amazon, or Google, or Apple that spins gold out of thin air.
One more interesting thing the upside down man said was that currencies will be the first to show some seismic shift, the canary so to speak.
The various central banks are using monetary techniques to stimulate their economies and its creating unbalanced pressures. The bubble pressure has to flow somewhere. It seems like its been coming to the US recently, and possibly when the rates go up, the flow might go even faster to the US. This would be in line with Larry's new high scenario, and we are pushing there now. That stats show a new high often leads to new highs. Remember the blowoff highs in the 2000's? Heady stuff. That the other scenario few talk about. Volatility at highs can be a different creature than volatility heading down.

Consider that since the pre-2008 economic peak the US economy has risen by 10% and the Italian economy has shrunk by 6%. Consider what Milton Friedman said when the Euro was introduced. Consider the global debt binge across both developed and emerging markets. Consider commodity prices and credit prices now and circa 2008. The currencies are singing now, yes, but that must be taken in a broader context. Importantly, currencies are not anchored by any "intrinsic value" or "floors" and liquidity globally in all markets has changed. Currencies are one of the last equilibrating mechanisms in this broader picture and all involved should be able to imagine scenarios and extremes others cannot.

A friend of my daughter works for Tesla. His parents described driving in a self driving car in San Francisico. As I drove through LA traffic, I thought of the many benefits self driving communicated net cars would have.
Almost all accidents are caused by driver error. If all cars were self driving, and communicated with each other, it would reduce accidents, increase traffic flow and congestion. Lane changes could be done quicker and more safely when other cars knew the changer's intention. Cars could drive faster and closer together where human reaction attention and reaction time were eliminated by communicating cars. Rear enders would be eliminated by front sensing brakes. Cars could self park like auto valets.

When roads were uncommon, they were privately owned and subject to usage tolls. Road travel was incredibly expensive because of the physics of friction and gravity (in a boat the water does the carrying; in a wagon the rims) so almost all freight moved by ocean and river which were the commons. When iron and steel rails solved the friction problem, land transport exploded - still under private ownership. Our present commons of free public roads only really go started in the 1920 after the development of pneumatic tires and leaf spring suspensions made transport of heavy loads possible. There was no practical way to put tariffs on the road usage but cars were so expensive to own that "traffic" did not become a problem until the combination of cheap gasoline and inexpensive used cars developed in the late 1950s.
This is not a difficult problem to solve, given the capacities of digital technology. What I find fascinating is how much the people who know that technology best (the folks at Google) are determined to use it to limit people's freedoms and prevent government's monopolies from dissolving under their own economic obsolescence. There is no social justification for "driverless cars" - auto accidents continue to decline and the injury rates for vehicles where people are passengers, not drivers - buses, vans - are far, far more bloody than for personal vehicles. This is a technology avoiding a useful solution in order to promote what will be an utterly useless green fascism.

This sounds like a compression algo. Music is decoded into MP3, to lower bandwidth. I heard an interesting article on NPR about someone who analyzed what is missing from an MP3. Turns out quite of bit of interesting and valuable information that makes music more beautiful is dropped. They claim the full data can be extracted, but I'm concerned. It will cause a lag and delay. I use tick and execution data in my work. I am guessing there are players that can get full uncompressed data. I am concerned the compression will alter the true nature of the trades, their times, and other info. I use DTNIQ who says they can decode the packets to full data, but why do I doubt this? Who will benefit from this?
Anyone else have a take on this?

I was actually at a conference where the group that developed MPEG audio presented. Interesting place - Mohonk Mountain House in New Paltz NY; well worth checking out, it's iconic for a number of reasons. I think it was the IEEE ICASSP conference at the mountain house where I first heard about MPEG audio.
But I digress: MPEG audio is what's called perceptual encoding. The (basic) concept is that you can remove information that people won't hear anyway and they won't be able to tell that it's not there.
It's not the same as the sort of compression used when you zip a Word document. As you suggest, there is a delay due to decoding it, but it's short and generally not relevant for a typical use case.
Compressing a stream of 'ticks' is probably very different. There's a lot of repeated data time-domain-wise so you could use something like run-length encoding (which is sort of what IB does) although I'm sure it's more complex than that. As you suggest, one would want something that has low time latency in the decode process. Happily, it's much simpler to decode than encode for most types of data compression AFAIK. But there would be some delay. But it's most likely lossless.
Finally, I have read and find convincing the idea that an uncompressed data stream of tick data would overload the data transmission channel for any name that had any serious volume. If you're co located at the exchange or pay for a private fiber connection to the exchange it could be fine but not over the retail Internet. Even forgetting about the data rate you'd need to store it as it came in without overrunning buffers and the buffering itself would cause latency.
So if you have $$$$$$$$$ and an IT department you could make uncompressed work but probably not otherwise. But as the encoding of this sort of data is probably reliably lossless it may be less of an issue than you're thinking of.
My 2 cents.

Scott Sumner, of Bentley University talks with EconTalk host Russ Roberts about interest rates. Sumner suggests that professional economists sometimes confuse cause and effect with respect to prices and quantities. Low interest rates need not encourage investment for example, if interest rates are low because of a decrease in demand. Sumner also talks about possible explanations for the historically low real rates of interest in today's economy along with other aspects of monetary policy, interest rates, and investment.

If real interest rates are in fact negative, then the FED rate is still high and offers the best return. Rates at banks are in fact negative when you subtract bank fees the return is negative. Its not real clear what negative interest rates are to me. I suspect it has something to do with international currencies and the strengthening of the US dollar, and the FEDs warning on the global situation. Maybe the US doesn't want a flood of foreign (Chinese) money.
Martin Armstrong writes:
The Fed is really caught between a rock and a very dark place. Yes, they have the IMF and the world pleading with them not to raise rates for it will hurt other debtors who borrowed excessively using dollars to save money. The Fed is also caught between domestic policy objectives that dictate that they MUST raise rates or they will bankrupt countless pension funds internationally and emerging markets will go into default because commodities have collapsed and they have no way of paying off this debt that has risen to about 50% of the U.S. national debt.
Gordon Haave writes:
Perhaps I am not understanding something. Is this saying:
A. We can't raise rates or emerging market economies will be hurt due to their dollar debt, and; B. We must raise rates because if not emerging markets will go into default?
This makes no sense to me but perhaps I am misunderstanding what he is saying.
Stefan Jovanovich writes:
The presumption of central banking in the late 19th century was this: through adjusting the discount rate on its own good as gold credit, the Bank of England could literally regulate how much net foreign exchange (specie) flowed into or out of Britain. The presumption was believable, provided that no one questioned that the Bank of England would redeem all its own paper in gold. After 1914 there were nothing but questions.
Central banks now have two presumptions: by talking about adjusting the discount rate and by actually writing checks to their national treasury they can control not only foreign exchange flows but also how much credit its citizens and domestic companies will use in the immediate future.
Montagu Norman went to an early grave precisely because he knew there was now way for Britain to have its cake and eat it, too. If the Bank of England's own paper was going to continue to be priced based on private demand and not ability to pay out specie, on demand, then either the Empire would have to restrict trade to its own colonies or counter-parties would be the ones who determined the discounts at which foreign exchange could balance (translation: the Americans would have to let their gold go overseas by running a persistent deficit).
3 Trillion in U.S. IOUs is supposed to give the Chinese "power" but that pile of another central bank's money only has use if it is spent abroad. Like the Americans' gold in the 1920s, it is worth nothing if it is not allowed to be drained away. There is no reason to think that anyone with a higher education will allow that to happen in China or, if that miracle occurs, that the politicians in this country will not respond with the same imperial preference mercantilism that guaranteed Britain would win the war and lose its empire.

So you really think we at Dailyspec are smarter and have more information on our fingers than the people at the Fed? I don't. In retrospect over many many years the Fed has done a remarkable job. I know, you people dis them at every turn, claim you know the answer, we know the answer, but the truth is year in and year out compared to what could've happened they have not done a terrible job. Probably I should explain something called upward drift for those who are not aware of it. It seems to be pretty important.
'Cyborg Chess' or 'Advanced Chess' is an area that might be of interest to specs in that humans are allowed to use computers during the decision making process. There is evidence that strong human players can add considerable value to pure computer play when the process is managed in the right way, for example Arno Nickel defeated Hydra in a correspondence chess match in which he used a regular PC against the the most powerful supercomputer in the World at that time. This event wasn't publicized as much as it might have been, but you can read more about Nickel and Cyborg Chess here:
I've experimented with 'Cyborg Chess' in correspondence tournaments in which computers are allowed. The results haven't been great, probably because I don't use deep calculation setting on the engine, but the experience has been educational. A major issue is in understanding where it is that I can add value as there's a temptation to either overrule what the engine recommends or be led by it indiscriminately. Probably a series of protocols would be a good idea but where does one start? Here's a provisional list:
1. Write down your list of candidate moves, in order, and then compare them with the top choices of the engine.
2.Consider whether this is the kind of position in which engines are likely to do better than you (ie highly calculative tactical ones).
3. Give greater weight to particular candidates based on point 2.
4. Check your top candidate(s) more carefully, perhaps using deeper engine settings, until a particular confidence level is arrived at.
It seems reasonable that different people might give a different weighting to their own choices versus those of the computer, but in either case it does seem that better decisions might be arrived at. In fact Nickel's achievement sort of proves that, and even if computers get so powerful that the more or less 'solve' chess the synthesis of man and machine should still have value in less finite fields.

"Cyborg Chess" by Nigel brings up the effectiveness of human versus
robot trading in markets. Certainly costs must be considered as well as
effectiveness the way it is in all the studies of robotic versus human
surgery. Apparently robotic beats laporofic.
There should be areas where the robots have to be turned off for the
evening where the humans could develop an advantage. It seems the robots
are forcing early capitulations in many markets which is presumably an
effect of their programs.
To list just two of scores of regular robot shutdowns that one knows of:
1. On Sunday nights in the professional electronic FX markets (using HotSpot as an example), one only has access to prices from 5PM NYC time unless you get on the phone and call a counterparty direct in New Zealand or early Sydney.
This 'dead zone' is almost completely without 'silicon based entity' interference and often sees a reasonable range that goes unrecorded. A stint in that dead zone is a prized achievement for FX traders learning how markets 'really' trade. Much like time on the floor of an exchange, it is an experience that is dying off.
2. Each night at 5 PM NYC time the professional electronic FX market goes dark for a few minutes as the value date changes.
After reopening, the market making algorithms kick in first with relatively wide spreads that narrow quickly when the Carbon based life forms start to interact. The HFT 'order facilitation' ( Ha!) kicks in next.
What is of increasing concern is that the lunatics are running the asylum. Meaning that the firm's running the robots are deciding when and why markets open and close rather than some supervisory body. I guess this is more a question of nature versus nurture.
Arguably, there is some marginal information that is helpful, in an accretive sense, to the buy or sell decision–from the opening procedures of robot dominated markets.
The first order possibilities for testing might involve: number of transactions per unit time, rate of change of spread contraction, the epps effect et.al. All for relatively short periods as the robo-market opens.
At a practical level, and without investing what I know to be substantial funds to study this issue, I believe it still comes down to basic conditionality, expectations based on that conditionality and finally path dependency.
Additionally, the predictive nature or otherwise of the situations introduced into the price generation process by exchanges, that I have previously posted on - must be tested and incorporated.

By their nature, cyborgs must look for fixed patterns. They have limited adaptability. Sudden bugs, unexpected changes, changes in cycles, and divergences will always surprise them. They can't anticipate. Their advantage is that they are as fast as their circuits, and comm allow. The unknown is how they perform in a complex system with other cyborgs and humans. As Nigel points out, a human can add value and beat a pure cyborg. Human foresight and understanding of human nature can add value.

Machines keep improving, some moving away from brute force approaches…
"Lai has created an artificial intelligence machine called Giraffe that has taught itself to play chess by evaluating positions much more like humans and in an entirely different way to conventional chess engines.
Straight out of the box, the new machine plays at the same level as the best conventional chess engines, many of which have been fine-tuned over many years. On a human level, it is equivalent to FIDE International Master status, placing it within the top 2.2 percent of tournament chess players"
Andrew Goodwin writes:
I still have my ticket stub from the match that Kasparov lost to Deep Blue in 1997 in NYC. Maurice Ashley was using the Fritz engine to evaluate the moves of the champion and the supercomputer in real time for the theater audience, as I recall.
Instead of making the next move optimization target the best calculable move, the supercomputer could make goal seeking calculations that lead the match to the most time consuming calculable end game for human competitors. It won that match with clock time to spare. That's the advantage.
The Chair's idea of a downtime for computer engines sounds sound for human comparisons.
Jim Sogi writes:
I would challenge anyone to quantify what exactly is the difference between a cyborg traded market and a human traded market. Sure it feels different, but how exactly? How do the numbers trade. Are there less big blocks? Are there fewer round sizes? Are there fewer takers on breakouts, i.e stop buy orders? Where are the numbers on the table?
Hernan Avella writes:
Difference? Generally speaking, most of the time, when bots are the market makers there is less friction, reduced bid-ask spread, more ability to get the trade done with less price disruption. Winners: longer term traders willing to pay the bid ask spread or less to get into or out of a position. Losers: human market makers who want to earn the bid-ask spread. They can no longer compete.
From the 1960s-1982 the Dow stayed in a range between 600 and 1000, with several 40% swings. Then came the great bull market.
Is there any reason why we might not return to such a range for 20 years or more? We are off all time highs, but with quite the penumbra around 1950s. Also, it's been a bull market for 7 years.
In real terms (adjusted for inflation) from the peak in 1966 to the bottom in 1982, that was a 75% decline in the value of the Dow, and a 29-year trough before a new high was made. The decline from 1929 to 1932 by comparison was 85%, also with a 29 year valley before the 1929 peak was surmounted.
Ralph Vince writes:
Yes, but in August of 1982, you KNEW the lid was coming off.
On Friday the thirteenth, after a languishing bear market, things jumped. It had a different feel to it. By the next Tuesday, the 17th, it was off to the races.
I remember it well. It was a complete change in market character from what had been going on for several years before it (at least since the Summer of 1980, and August of 82 was profoundly different than that even).
My point is, you didn't have to be a contrarian to know something big was just getting going. It came in with bang,
We live in an era where damn few remember — if anyone ever knew — how to read a tape, the pace of whats coming across the Electro-Lux. I've tried to catalog this in terms of patterns of volume bars. If you go back and look at the Friday, August 13, 1982, it occurred on a low volume bar turnaround — v. bullish (assuming a descent into it).
But the real tell came later — the 18th, a high volume bar day, the end of the short term runnup, On the 18th, the DJIA dropped a small amount, on very heavy volume, marking the high that day as an interim high that should hold for a few days. Not only did the market blow through that, showing extreme strength, but the coup de grace was the following week when the market continued higher on very high volume. Often, a single bar making a high on high volume markets an interim high (there are fine points I am not mentioning here), or, even stronger still, if there is a few bars in between and another high on high volume. But a series of 3 or more bars, on very high volume, where the market continues to grind or grind higher, is very, very bullish.
There was a confluence of factors leading up to that — negative sentiment, bank failures, bankruptcies, etc. amid an environment of declining energy prices, falling rates, technological breakthroughs (as evidenced by Ipos in the 18 months leading up to it — Apple, Genentech, etc.) the pc was in its infancy , Apple was talking about "Lisa," the mother of Mac, there was by many people's accounts, a political climate favorable to business.
There are perhaps many similarities to today, and many differences. I suppose it could happen, could happen in the coming months (look at the advances in cancer treatment, and I don't think we've even begun to feel the effects of the technological advances afforded by a true, coast-to-coast high speed network drones and mass transport, or even the productivity created asa result of the handheld devices most of us use today). But if it's anything like the last, great bull market, it come in with a roar, and I would expect it to be evidenced by inexplicably high trading volume that generally persists.
I miss the noise those Trans-Lux jets made, with those funky fluorescent black lights and those little colored pegs. They were crude, but effective. The bars around the exchanges all had jets so you could have a drink and still see the prices, real time. Nobody minded in those days if a broker went down to the bar for a quick one or three as long as they were good earners. The Germans, Irish and Italians were the ones who went to the bars for a quick one during market hours……..the Jews at the CME always wanted to maintain decorum and control, and never show public intoxication…..the drug of choice for the Jews was cocaine and naturally they didn't drink like the Germans/Irish, and the lack of good drinking establishments around the CME was evidence enough. The bars around the Merc were never legendary like the ones at the CBOT like Broker's Inn, Sign of the Trader, Trade Inn, and Alcotts around the corner. Those bars were in a league of their own and the back stories of what went on in those establishments would be worthy of Runyon or Hemingway. I have sources that have the 1970's Russian Grain Deal being worked out at a back table of the Broker's Inn. Whether or not this event occurred and is verifiable, I wouldn't say it would surprise me. I've seen 20mm tonne cash grain deals done on the back of a napkin and with a handshake.

It took the S&P 500 7 years to regain is 2000 high, but it could not hold that level for long. It was not until 2013 that the S&P 500 again reached its 2000 high, so we already had a retrospectively-defined trading range for 13 years. I have a hunch that the next "great bull market" is already here. The so-called millennial generation in the US is larger than the baby boom generation. I keep noticing things about this decade that remind me of the 1980s, including a commodities bust and concurrent strength in the US dollar and US stocks.

Steve gets my vote. Part of what happened in the 80s was the destruction of previously secure franchises. Mr. Walton's stores destroyed thousands of local "downtown" merchants who had enjoyed distribution monopolies in the villages and towns of what became known as flyover country. Even as AT&T decides that satellite streaming of NFL football games is worth $3200 a customer, the kids are growing up wondering why anyone would be so stupid as to subscribe to a service whose ability to provide programming on demand is as ancient as a Betamax recorder.
But where can rates go, Steve? Or perhaps it isn't the direction of rates, so much as their absolute values?
The other big element that concerns me is not the systemic liquidity problem (which we had a taste of on 8/24) but that volume has been tapering off throughout this run up from the 09 bottom.

On my last haircut before moving, I gave my regular lady a $100 tip on a $17 haircut (applause line here?). That small gesture brought her to tears. She is a very interesting older woman. I've enjoyed talking with the past few years. She knew I worked in investments/trading and asked if I had any ideas for her. I asked about credit card debts and she told me she just cashed in 25K of an IRA to pay down 25K of credit card debt, yet already had accumulated 2K since then and was getting in the hole again. I might invite her down to do some murals in my kids room, and perhaps do some studies on trees (She is an artist who made a living cutting hair for the last 40 years).
The point is (perhaps? At least the relevant one?) is the deadly financial problem of never having working capital that provides the flexibility that keeps one off the spike of usurious interest.
This lady had been sold on long term investments (by her branch XYZ big box bank) in high fee mutual funds with perhaps at best a 5% yr expected value over the long term, while paying off 25% interest rates on credit cards. The scams run on the lower middle class or working class are obscene.
And it is not income. Clearly if these folks can pay these obscene high interest rates, they can afford much more than they have. The problem is that they never understood the idea of having "working capital". I told my friend that her best investment is at least 6 months of living expenses in the bank. As basic as it is, and at such a low margin for error that standard that is, for many it is an alien concept. Her recent issue was a car repair that blew up her budget and started the credit card problem again. With no working capital plus compound interest against, it is like a giant pit metaphorically with wood spikes and lions at the bottom to gobble one up.
So in trading and investing, how can we use this idea? Victor has taught "never get in over ones head" as one of the key tenants of speculation. So how do we manage our cash in our speculations, investments, life's "issues" to have the flexibility to seize opportunities and avoid pit of being bent over a barrel–while still getting a solid return.

The people that Ed is referring to don't have the mentality to accumulate wealth and get rich. They are sold on the "here and now" mindset. They go into debt to satisfy the here and now. Something will always come up that will prevent them from succeeding. The only thing they are really good at is coming up with PLE's (Perfectly Legitimate Excuses) to justify their failures.
They are defined by their failures.
Especially with respect to this site, I would wonder the data and testing behind those assertions. Otherwise, one might consider them to be presumptive, elitist, and uncharitable, with mean-spirited implication. But for the grace of god….

Sorry, I disagree Scott. Ed is correct, it's a matter of education and coaching. Have a plan, believe in the plan, stick to the plan.
The average working poor Josie is not a loser. It's the average bank has learned they are more valuable dumb and paying fees than smart with small accounts. The stats say that the fees are several hundred dollars per person in the USA. So some are paying several times that. The banks have the average poor working single parent or mom in a snap trap that they can't figure how to unsnap and lift the door.
The first thing I tell kids is that you need a minimum of $1,000 in emergency cash preferably $2,000. Have a garage sale, stop buying lottery tickets, no gambling, stop buying new clothes, stop cable, and stop smart phones, etc until you have that emergency fund. Also budget, if you can't fix the budget to the pay, downsize housing, get roommates, no car, bus, pay for car pool, whatever it takes to have a workable budget. Then save for the 3 to 6 months expenses in a cash account ready for a big expense. Only then should you invest.
Most people in this problem don't have anyone they can trust to give them the advice and perhaps the tough love they need to stop living in denial. The truth is the banks want the poor.
What does this mean for "investors". Frankly I think most investors have it wrong. It's not so much managing your risk as it is managing your cash flow first, then manage your risk. You can take a lot of equity risk if your investment horizons 20 years out.
Also the lesson to investors is just because someone is in the best position to give you advice and would make some money off you if they gave you that advice, it doesn't mean they will give you the advice that's in your best interest when it conflicts with their best interest. Their best interest is CMA (cover my …) by silence or sin of omission. Then it's to make more money by selling what gives them the most profit to "cover" you like payday loans.
The thing I practice (and I don't know if it adds any edge that can be computed) is to always take some off after a good run. No mater what, be it trading, investing, bonus, etc. Never spend it all–or even most of it. Put it away for when SHTF, because as day follows night, it will…

A major part of the problem is the thinking that makes the credit limit on credit cards equivalent to ones own money.
For my part, I will never willingly stop at a gas station that has two prices for gasoline with one higher for the credit card user than for one paying cash.
In a world where there are card rebates on gasoline, what is the point of acting responsibly with credit when those who did not act responsibly get subsidized by those who did. The dual pricing also serves to support a cash economy against the public interest.

I feel that I am unique on this site as having been in this hairdresser's situation for most of my life (Hello, Peter). Obviously this is not due to a lack of economic education or upbringing. I feel that the factors include a lack of skepticism regarding my own appetites, a lack of faith in the future, a certain immediacy in response to the world. These are traits associated with immaturity, to which I confess. Of course this leads to tremendous inefficiencies, even when viewed from a purely hedonistic perspective, but it does have its compensations.
I do not regard Scott's comments as elitist, presumptive, uncharitable, or any of that baloney. On the contrary, I find the the use of the word "uncharitable" to be condescending. I do not feel that people in my position are a fit object of charity.
Everyone has their irrationalities, and they are often incomprehensible to those who do not share them. Scott's words are simple, honest truths, which many people (including me) would benefit by internalizing to a greater degree.

It is good to have an emergency cash for at least a decade; locked, untouchable for trading or similar. The rest can be at risk. And after MF Global steal from client accounts (is Corzine still free?), I think it is prudent to keep as little as necessary with FCM. In case of a brokerage failure, the jurisdiction matters (Switzerland is preferred, the UK is too slow but ok, then Canada, and the last option is the US broker).

I entirely disagree; emergency cash has a shelf life which is very short, and our perspective warped as we are speaking in terms of USD.

People are taught that "saving" is virtuous, borrowing a vice. I would contend that we have crossed to Rubicon in terms of the notion of stored value — no more able to contain that vapor than we can a bottle of lightning. The circulation brought upon by a zirp world, turning all those with savings into the participants at a craps table, the currency being used the product of a confidence game, among the virtues to be taught to tomorrow's youth is that of creating streams of income — things that provide an economic benefit their neighbor is willing to pay for, as opposed to a squirrel's vermiculated nuts.
"Stored value," is a synthetic notion we have accepted and teach as a virtue. It has no place in nature, it is a synthetic construct, one that is not scoffed at in the violent, life-and-death world of fire and ice. Young people need to be taught the fine distinction between the confabulation of "storing value," and that of using today's fruit to generate tomorrow's.
Stefan Jovanovich adds:
From the other Stefan: I agree Ralph. "Stored Value" is another part of the economist dream that platonic ideals can be found. Money is and always has been one thing: the stuff you could voluntarily give to the tax man that would make the King find another excuse for throwing you into the dungeon. The gold standard did not change that; it simply gave the citizen a chance to make the same kind of unilateral demand on the government. It is hardly surprising that the fans of authority and "government" hate the Constitutional idea of money as Coin. How can you have a permanently elastic official debt if the citizens can ask for payment in something other than a different form of IOU?
However, Stef does have a point. Having a hefty cash balance is a wonderful gift; it gives you the time to figure out your next move. The sacrifice is the absence of leverage; the gain is having literally free time.
Scott Brooks comments:
There are a lot of companies out there that take advantage of them and the bad advice they were given from their parents. Banks certainly do. Then you've got insurance companies and brokerage firms selling them crap products as well.
But that doesn't hold water in today's society with Suzie Orman and others like her being nearly ubiquitous on the airwaves and net.
These people live beyond their means. Plain and simple.
Yes, they lack education, but even with education available, they don't take advantage of it. They are just doing what they were taught as kids. For far to0 many of these people, as long as they've got enough money for their 1-2 packs of cigarettes/day and their quart of Jack/week, they go and live lives of quiet desperation, hoping that they don't lose their jobs and are lucky enough (i.e. like not spending money on stupid stuff is "luck") to pay off their debts by the time they are in their early/mid-70s so they can live out their remaining few years (if they even make it that long) on social security.
I know. I grew up with these people. I know how they think. But for grace of God (as was mentioned earlier), I might have been one of them. But for some reason, I was blessed with gray matter that works, and I saw the error of those ways, and I was able to get out.

Scott, since this is the DailySpec let us bring a little science into the discussion, even if it is social science.
Where we differ is not what is causing the hairdresser's problem. It is in what can be done about it that I differ. I believe you can coach people to delay gratification. I coached kids that never did homework before and got "D's" and "F's" during a summer and by fall the kid was an "A" or "B" student. You probably owe a hardy thanks to the coaches in your life.
Perhaps the greatest social science finding has been the "marshmallow experiment" done at Stanford. They did test on 600 4 year olds telling them if the child did not eat a marshmallow for 15 minutes after they left, they would get a second marshmallow. 1/3rd of them made the whole 15 minutes, a small percentage ate it immediately after the others had waited various amounts of time. They followed up on these kids several time in the last 40 years. Just about every way you can think of to define success was highly correlated with the time the 4 year old delayed gratification: SAT score, college/HS graduation rate, credit scores, long term committed relationships, contentment etc. And almost any way you can define failure was inversely correlated: jail time, high school.
The correlation was stronger than IQ, social economic status at 4 years old. In other words even the dumb poor kid that delayed gratification was happy/content/successful 40 years out. He may not be making much but he is happy with it.
For a humorous view of this experiment reproduced: Joachim de Posada: Don't eat the marshmallow!
Rogue waves can be defined in many ways, yet the one I prefer is "a wave of extreme severity that appears unexpected even to an expert". Given that definition, rogue waves do exist, yet there is no evidence that they would be globally more frequent than conventional (non-linear) waves theories predict, they just don't happen where and when — i.e. in the most extreme sea states — one would expect them. There is no evidence either that the "modulational instability" theory that my colleague Prof. Akhmediev puts forward to explain them would not apply: the theory was validated in wave tanks, optical fibers and plasmas. It is just impossible to know whether the necessary boundary conditions are satisfied in nature. Several points may be noteworthy to the Specs:
1. A recent article shows that rogue events can be empirically predictable, but that for ocean waves the delay would be of the order of the time needed to shout "Buddies, grab something and hold on to it!"
2. "Normal" extremes are at least as frequent as "special" ones, and all indicators based on breather theories such as Akhmediev's have false alarm rates of at least 90%, perhaps 99%, and still fail to warn of about 10% of actual rogue waves.
3. Experienced sailors deny having met "rogue waves". They say that they encountered waves that were rogue, they capsized or broke some ribs (Roger Taylor, Isabelle Autissier), but when you discuss it directly with them, nothing that they were not expecting and had not prepared their ship for.
4. Only a very small percentage of fatalities occur well off the coast (Nikolkina & Didenkulova), most of them happen at the coast or in shallow waters where victims feel wrongly on safe ground or in safe waters.
William Weaver comments:
Your fourth point is similar to many car accidents happening within a small area from home. People make more mistakes when they feel comfortable. I'm not sure how this changes when accounting for activity though. For example, you could normalize accidents per mile driven and then compare close to home versus far from home, or do a similar normalization for the study mentioned with at sea fatalities, which I have not read. It might be helpful to measure after splitting into bins for types of vessel (cargo ships might have more miles, farther from home travel and less fatalities), and by type of mariner, which might be self defeating as it is more likely less experienced seamen would stay close to shore ( which is not the case for drivers staying close to home).
It seems like a data set prone to torture someone. But do we make more mistakes when we feel safe? The opposite might be true too. My observation is the difference between good and great traders is often the number of mistakes they make. Bring back the checklist posts?
Jeff Rollert writes:
I see some sample issues. Most sailors (N) do not venture more than 20 miles from the coast. The ones that do are orders of magnitude better prepared (boat) with experienced crew. So I suggest the distribution is bimodal.
Also, there is more than one kind of "rogue" wave. One is an overtaking wave, which is when two waves combine; the second, and more deadly, is when the wave comes from a direction that is unexpected. In my experience, these are the most deadly, as they roll (or broach) the boat. They are also the hardest on the structure of the boat and hit the weakest points harder (deck access from the stern, control or bridge room windows and electrical systems). For fisherman, they dread losing engine power, as the boat becomes exposed in the same way, as fishing boats have the windage at the bow, which turns the boat and presents a breaking wave to the stern.
Lastly, looking at single vs combined storm fronts also messes with their structure.
IMHO, they oversimplified their model.
Jim Sogi writes:
Surfers expect at least 1 wave each day that will be 3-5x the smallest wave. It's called the wave of the day. In a random sequence this would be one of the far tails. They tend to come with the incoming tide as there is an extra push from the moon.
I think the rogue waves in the ocean might be 20x or more if there were a number of storms with crossing wave trains which could combine. It's the cross chop that creates these large events through random combinations. Rogue is often and mistakenly used as unexpected. Sailing through large parallel swells on a calm surface is quite easy. Sailing through a cross chop is very tiring and rough. Refraction and reflection from shores often make coastal sailing rougher than in the mid ocean.
What always surprises me is how calm the ocean tends to be. You would think it would be rougher given how big it is.
Tempura, well known Japanese dish, is from the Spanish and Portuguese traders that came to Japan in the 1800's.
My friend dropped off 10 pounds of Marlin from a 400 pounder he caught. I love fish and chips. Here is a great recipe for the batter.
2 egg yolks, 2 cups ice water, and 2 cups flour. So easy, and so good. Don't let it sit, and be sure its lumpy.
I can't believe I haven't seen this before. I used to struggle with a beer batter, but this is better and easier. Great fish and chips, or tempura.
Coat with batter and Cook in hot oil 1 inch slices for a minute or so til brown. Marlin can get tough if overcooked. Pumpkin zucchini, beans and mushrooms made great sides.
At what point in the day do stocks reverse direction? The Chair mentioned after lunch. In theory it should be when there are more buyers than sellers, or the momentum of buying over whelms the downward pressure of sellers. Traders, like many other organisms, tend to move in herds, or try to follow. Whether it follows through to a reversal, like just now, or whether it is a head fake prelude to further drops is important to distinguish within one's time frame. It is important to catch the turn at the cusp rather than after confirmation when it is probably too late to capitalize efficiently. The data can signal those points in real time but there seem to be about 3 or 4 things or more going on at once in terms of forces at work or data streams to consider and factor in. It seems also to be a computational capacity problem and data flow issue. That's why I've always thought a 3 dimensional approach would be helpful.
The other big problem is to weed out the big trend days and not get caught under the falling knife. One thing I use to try weed out those trend days are the 10:1 updn signals that Marty Zweig talks about as signals, but not in the same way.

I find Paul's observation very relevant and I have noticed that at least some of these time of discontinuity have regularities. The activity picks up some minutes before. There may be predictive value in it but likely very short term.
In response to "traders move in herds": You have the herd, yes, but then you have the cliff. More and more "optimal execution" algos for firms running large money are actually designed to spot the short term herd and use that to get into positions in the opposite direction. I'm under the impression that this has become extremely prevalent in equities, and is the main cause of much of the new normal price movement characterized by many traders as having "lack of follow through". I've recently used the understanding of this characteristic in my own design of algos with good success. (I am a discretionary, short-term hedge fund trader and newly turned quant).
There is a lot of variation between markets. As we know, futures and equities are very different beasts. Even between equities there are large distinctions. In the less liquid stocks I like to accumulate intermediate to long term positions in, I have found that the algorithms that exist to exploit small orders (what appears to be Market makers blocking competing orders) and accumulate position algorithms are extraordinarily stupid. The only issue for the trader is, if you note this and take advantage of it systematically, it is almost certain to be some form of criminal act. As we have seen, the manual trader is not allowed to exploit or beat the dumb algos of big firms. One other thing I have found is on certain days it seems that relatively small aggressive orders can change the trend of the day as (it seems) some algos look for others to establish a bottom level that amazingly they then seem to defend and even accumulate from. Note this is not really short term trading stuff, more notes I've made when buying my list of stocks.
This trader has the questionable habit of buying at the highs and selling at the lows to see what kind of (paper) is around. I've never been able to follow the herd, instead I try to re-direct it in my market.

This article on a pairs trade has more mumbo jumbo in it than can fit in a big barn. And it brings to mind the absurdity of pairs trade in the first place, and how much money is lost in trying to implement, and how great it is that almost all the short funds have gone into oblivion, that such funds and ideas still provide us with trillions of dollars more that those who look to the drift can fletcherize. One notes a comparable set of "opportune " articles that the "Dax has entered a bear market today".

Here is an article from the world of transport engineering. It's not too much of a stretch to apply something similar to observations and timings of magnitudes in financial markets:
Extract: "Why Buses Bunch at Single Stops"
Maybe you've waited at a bus stop for longer than usual, and your bus finally shows up. And then, immediately after, a second bus on the same route pulls up right behind. What gives? Why can't they stay evenly spaced to improve everyone's waiting time? Lewis Lehe provides an explanation in a small interactive game.
Two buses travel along the same route, starting off in opposite positions. They make stops and pick up passengers right on schedule. But then add in your own small delays, and you see bunching relatively quickly. It really doesn't take much to throw off the equal spacing…..'

Watch the ocean for a while, or the beach. Random waves cluster to form set waves, larger than the rest, or rogue waves, which can be magnitudes greater than the average. I believe this is a function of randomness or alternately pattern formation from simple binary functions a la Wolfram.
Here's some good information about Three Phase Traffic Theory.
Jim Sogi writes:
When I go to the US Mainland and drive the big freeways for long distances, I try to drive about 2 or 3 miles per hour slower than traffic. Most try to drive as fast as they can and bump up against slower traffic groups, and results in waves of clusters of cars. It's more effort and emotional cost to try drive fast and requires more attention to try pass, notice and avoid slower cars, and cars next door. Driving a bit slower requires less attention, less stress as you set you speed, and allow other drivers to pass, avoids coming up on slower traffic, and allows you to drive in the spaces between clusters, the "lulls" so to speak. I'm not in a rush and find it more relaxing and you can see the clusters in the distance, and adjust to drive between them. In large urban areas, the clusters tend to be time of day (rush hours) and location oriented, except for accidents.
In markets, vol clusters and it's good to be aware of the lulls and clusters, the timing of them, the length of the lulls. It's like the lulls and sets in surfing. Trading also seems to cluster around the rounds, and time of day (arc sine).
In playing and composing music, it's important to leave "space" in the music, where there are fewer notes to allow emotional development.
Jonathan Bower writes:
Mr. Sogi makes some very good observations. I drive 150 miles round trip every day for work. I see people in such a rush to "slow down" when they inevitably meet slower traffic (or jam). Maintaining a high average speed is much more important in determining length of drive (and better on gas). There is also a strong behavior bias to get in the left lane that frequently staying right, particularly in heavy stop and go, is frequently and consistently optimal.
Jim Wildman writes:
And mathematically, except on long, open road drives, speeding won't save you signification time even assuming you succeed in increasing your average speed.
You can't save 5 minutes on the typical 20 minute commute by speeding. You can if you are willing (and able) to run stop signs and stoplights.
I used to drive from East Texas (Longview area) into Dallas every day (about 115 miles). It was my observation that most radical speeding (10 MPH over) occurred where it would do the least good. Very few drivers speed in the truly rural areas, but once you get into the more potentially congested areas, the number of speeders goes up.
David Lillienfeld adds:
I've found that the frequency of speeding is inversely proportional to the density of police cars on the side of the road. The result is that you have lots of speeding going on on the interstates, punctuated by islands of drivers going at the stated speed limit. I don't know that the state makes much off of speeding tickets in this setting; I do know that it presents a nice the opportunity for accidents as cars slow down and then speed up. Twice, I've seen cars flip in the course of trying to avoid an accident while slowing down—once was just out of range of a radar gun.

We're talking about watch sales around here. Rolex apparently sells 650 million in watches each year. Susan says that wearing a watch these days is like jewelry for men, and that it's useless since everyone has a smart phone. We're thinking about Apple's watches. They'll have to compete with all the other watches. Supposedly they forecast it to use up 1/2 of all the gold production in the world. I wonder when Apple will stumble and launch a product that doesn't set the world on fire. Samsung wearable watches apparently didn't do that great. What do you think, and how will it affect the price of Apple. We just bought some on the news that they had to pay 600 million out of 150 billion in cash on a patent suit, which will probably be reduced to 10 or 30 million.
Stefan Martinek writes:
I agree with the view that watches = jewelry, but then it is more about IWC Portuguese watches in platinum having an unassuming steel look and simple elegant design. Apple is not a competition here.

A watch is a perfect accoutrement for a man as it is rooted in a practical function. The form and design however vary greatly. They can be showy and expensive or simple, like the Timex my father had. Men like things that have a purpose. Watches are handed down from fathers to sons or daughters for generations. The Tank watch is one of my favorites though I don't own one. Fountain pens are in the same category as would be certain sporting gear like classic hunting rifles, bamboo fly rods, Hardy reels, or Swiss pocket knives that every man used to carry. For Apple I know design is very important along with function which is a good start for continuing this tradition.

I got a very nice waterproof sport watch used at the Salvation Army for $6. The guy at the jewelry store laughed when he saw the price tag and the battery was $15.

If the watch were small, had a phone and music and alarm, and GPS and the battery lasted… maybe.
I know we've done a million studies showing the full moon doesn't predict squat about the market, but tonight's blood red moon full eclipse sure was accompanied by big moves in the market.

I am reading more and more about use of statistics to predict human behavior. We saw it in athletics, but we also know gugl and fcbk use it extensively. Target and most retailers rely on it and use it, and so do dating sites to glean users preferences, whether they know it or not. Credit companies use it. It's big business. But it's not very out in the open because most people find it incredibly creepy and invasive. Yet they continue to use FB, Gugl etc. Where is the line of privacy vs. prediction vs. voluntarily disclosed info and the use of it, the aggregation of the data, sales of data, use of data? It's a new world and there needs to be a discussion about it. There a some very talented statisticians on this site I know. Market data is used as a predictor of price action and people's preferences or habits. I am sure there is other correlated info out there that predicts price action. The question is how is that data, and what data is it that predicts price movement?
I'm reading one of the best training books I've ever read for training for endurance sports, which they define as almost any sport lasting more than two minutes. Training for the New Alpinism: A Manual for the Climber as Athlete House, Steve, Johnston, Scott. They draw on many studies from high level Olympic athletic training and physiology.
Technical physiological detail supports their theory. In a nutshell to train for endurance sport, duration as opposed to intensity is key. Building up an aerobic base where you can exert yourself without hard breathing is key to to building mitochondrial mass, capillaries and appropriate ST muscle fiber which builds endurance. High intensity is not a short cut, and can lead to a decrease in endurance and performance. Cross fit is an example of high intensity.
There is no shortcut. It takes long hours building a base for endurance. The effect builds over years.
Larry Williams writes:
I would add to this discussion that endurance does not win races. The winners are the fastest runners, skater's bikers, etc.
When the marathon running aspect of my life began I was doing 100 miles a week, ran 50 milers and all that but could never qualify for The Great Marathon; Boston, as I had to post a 3:25 at a sanctioned race to qualify. I was then running 4 hour marathons, and while I could run all day that was not enough.
Once we began doing speed work on the advice of a Kenyan runner who, while running with I asked, "What do I have to do", was given the simple answer, "run faster".
So off to the track we went for speed work and that on— top of endurance— got us to 4 Bostons, one with Ralph V.
There is a difference between completing a race, triathalon, etc and wining. Winners are fasters and work very hard to gain speed.
Seems like this applies to the markets in some fashion but I'm too slow to put that all together.

We're always taught that staying in the game is the key, because that's your prerequisite to catch the once-in-a-lifetime move. But then again, ascribed to palindrome: it's not whether you're right or wrong; it's how much you have on when you're really right!
Larry Williams adds:
It's that delicate balance between spend and endurance– above average performance and staying in the game— in our game it seems. At times I have had speed in trading, competition, and like all in this list we have endured, but getting both at the same time still eludes me.

Anatoly Veltman writes:
I don't think Buffet only has endurance. He'd been given valuable chunks on silver platter.

It seems like being given valuable chunks came after 1990, when he was already a billionaire. He made his first million in 1962, and a million was worth a little more back then. Perhaps someone has the goods, but it doesn't seem like he built up his fortune early on on anything but taking advantage of available opportunities. Early on the opportunities were not flexionic, but later on they got to be that way more and more. He will do or say anything to make a buck, but was he given or did he take what he saw?
As for only having endurance, it would appear based on his objective net worth that in acquiring wealth endurance matters more than speed, unlike marathons.
Rocky Humbert comments:
Mr. Rogan makes a key point which should be underscored. The tortoise beats the hare in investing because of the law of compounding.
In a marathon, the objective incremental value of the runner's speed at mile #2 is the same as at mile #22. That is, the marathon result is a simple sum of the time used for each mile.
In a lifetime of investing, the incremental value is different at year #2 versus year #22 … because net worth is a geometric series due to compounding.
There are many subtle aspects to this — the effects of volatility on the compounding, and the effect of a bankruptcy in year #1 versus year #22, etc.
Lastly, to the extent that one believes that there is a random/luck/chance is a factor, the turtoise will do even better than the hare.
Ralph Vince writes:
Good points Rocky (ever-prescient, except in matters matrimonial and matriarchal, in my humble opinion). In reading what you wrote though, the following question comes to mind (and I am unable to answer it, perhaps you or someone with a more sports-physiology knowledge can — my interest here in in the mathematical function pertaining to…).
There is not difference in benefit accruing to the marathoner by a given speed at mile 2 versus mile 22. However, is there a tradeoff a cost, involved between running wither of these faster that would indicate a particular strategy as being more preferable than another? I know individual marathoners may have a different take on this, I'm more concerned with the actual physiological function however.
Overall fitness requires strength, speed/agility, and flexibility. The mental component is extremely important as it is the brain that gives the signals to the muscles to act. If there is no deep reserve, or lack of strength, the brain senses this and pulls back autonomic functions. Motivation however allows the brain to tap the reserves of strength and endurance in times of need.
Each individual has different training requirements. Many a sport trainer or coach has found this out the hard way. Each individual reacts to training in different ways at different times in the training regime.
Training actual changes the body and brain functions. Mitochondrial cellular mass actually increases, as does enzyme production and along with muscle mass and function.
Recently I started logging my training efforts in a quantitative manner. Very helpful.
Overtraining is a common problem. A typical cure is to increase training, but it is counterproductive. When you feel tired, cut back, or rest. Your body is telling you something.
Time is unidirectional and relentless. We can never go back. There are no Mulligans. Music performance is good training to understand time. Music has a beat or a framework and the notes have to fit in in time. Beginners have difficulty with tempo and keeping up with the framework. When they make a mistake they try to stop and go back and redo the part. It doesn't work. The show goes on.
A curious thing about real time is that it fluctuates in tempo. In markets opens, closes, night all have different tempos. When you're in a trade, time seems different. When you're relaxed time is different than when stressed. When you sleep, time disappears to you. Time, in reality according to theory, is relative to speed. Delay or lag in a correlated system is very difficult for people to make proper adjustments to achieve a steady state. This is the thermostat problem. This is the FED's Problem as well. This is a portfolio balancing issue too.

People generally cannot understand or have difficulty understanding or picturing exponential growth. There is a story about the inventor of chess when the King condescendingly asked him what he wanted for a reward, the inventor replied that he would like the number of grains of rice, which when starting with only one grain, doubled in amount for each square on the chess board. The King laughed and thought he got off so easy. This same inability to picture compounding growth interferes with a long compounding hold of financial assets.
The same lack of ability to see compounding growth applies to study of past growth. People understand linear growth more easily.
Vince Fulco writes:
The inability to see compounding growth interferes with the study of nearly everything I might add. We tend to think that evolution is responsible for much if not all of the world that we see, a function of random mutations that have a selective advantage. Consider, after all, the universe is about 18 billion years old. In seconds, this is 60 x 60 x 24 x 365.2425 x 18 x 1,000,000,000 = 5.68e17.
"Random mutations with a selective advantage." Yes indeed. A thousand monkeys wailing away on typewriters will eventually happen upon Hamlet.
So let's examine that (it provides an insight into the astounding character of exponential growth James writes about here). Only considering the line "To be or not to be," which comprise 18 characters. We will consider the space a character, and make no distinction between upper case and lower case, require no punctuation, but rather a keyboard for the little apes having only 27 keys. The probability of any one monkey typing only this line is 27 ^ 18 = 5.81e25
To put the relative differences into perspective, if I could take a thousand monkeys, 18 billion years ago, and permit them 5,000 keystrokes per second, we would have about an even money bet that, without regard to case or punctuation they might, with a probability of about .5, come up with something like "to be or not to be" and much less all of Hamlet.
Natural selection, whereas I do not contest its existence, does not explain a whole lot as clearly not enough time has elapsed since the big bang.
I'm wrestling constantly these days with allocation structures based on similar matters, where a copula of discrete outcomes (say, the copula of rolling a pair of dice) posses 21 possible, distinct outcomes such that the branch out across elapsed consecutive trials gets unfathomably large quite rapidly. Even with parallel processing (more monkeys, more typewriters) the problem reduces, but the scale remains too enormous still as a result of astounding nature exponential growth.
Henry Gifford writes:
The relatively new field of epigenetics has some very interesting answers to the astute observation that random mutation alone would have taken too long.
Stefan Jovanovich writes:
So, one starts with a "known" fact that is not a fact at all — monkeys sitting at a typewriter writing Hamlet. Then, one proves mathematically that the fact is not probable; and that, in turn, raises a question about the validity of the current best hypothesis for explaining the organic world around us — namely, that through natural competition fortunate mutations win.
It seems to me that we are all saddled with two very stupid terms and our minds wear them like blinders - Marx's word for the results of enterprise ("capitalism") and the Darwin's unfortunate choice of the word "selection" for his title. "Evolution", especially in the eyes of its admirers who try to turn its theory into a fact, somehow takes on the certainty of religious moral authority; it "explains" everything just as Marxism does. No, it doesn't; but Darwin's theory does withstand the Shakespeare test. For one thing, there is no evidence that any monkey of sense would go near a typewriter.
If Marx fudged the data wherever possible to make history say what did not, in fact, happen, Darwin did the very opposite. He thought there could never be enough data to "prove" his hypothesis; but he did take heart that there was, at least not yet, no data that proved it wrong. He does seem to have realized that he had been proven wrong in his choice for the title for his first edition. But he deserves a pass for that.
In choosing On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, he was not endorsing the Southern way of life or Dickens, Carlisle, Kingsley and Ruskin's defense of Governor Eyre. Hardly. Darwin was one of the very few people who had the courage to speak up, along with Huxley, John Bright, and John Stuart Mill. In using the words "race" and "species" Darwin was using the biologist's definition - could male and females produce offspring. In the rare times when he was asked about human "races" Darwin was genuinely bewildered by the question; there was, in his view, demonstrably only one human species/race.
That leaves the point HG notes. Useful mutations may have had their randomness accelerated.
"According to classical evolutionary theory, phenotypic variation originates from random mutations that are independent of selective pressure. However, recent findings suggest that organisms have evolved mechanisms to influence the timing or genomic location of heritable variability. Hypervariable contingency loci and epigenetic switches increase the variability of specific phenotypes; error-prone DNA replicases produce bursts of variability in times of stress. Interestingly, these mechanisms seem to tune the variability of a given phenotype to match the variability of the acting selective pressure. Although these observations do not undermine Darwin's theory, they suggest that selection and variability are less independent than once thought."
Jeff Watson writes:
We should revisit the Second Law of Thermodynamics, and how some scientists speculate that it enables the formation of life itself. There is some very good peer reviewed literature regarding the second law and life.
Anyways, there are some very interesting challenges to Stanley Miller's glass jar filled with water, methane, ammonia, and hydrogen.(I believe he got his PhD from the same place as the Chair). In Miller's experiment, he blasted it with an electric arc for a long time, and out of this primordial soup arose half the amino acids required for life.
Fifty years later and biochemists and physicists today are on the verge of creating an artificial organism that meets all the criteria of life.
Mr. Krisrock asks:
In evolution it's the survival of the fittest, so how come so many species still exist?
Gary Rogan writes:
There are multiple niches in the environment, so species specialize. The famous Darwin finches were shown to adapt their overall size and beak size to different sub-environment both geographically and on the same island. It's the same reason why Toyota doesn't operate supermarkets or Procter and Gamble doesn't own any airlines. It's easier with conglomerates: at least they can get specialized departments, but imagine a lion competing with heat-loving microorganisms in under-water vulcanoes.
Now the jumps: just because not all species that died out left any identifiable remains, doesn't mean they didn't exist. The absence of evidence is not evidence of absence.

I've been thinking about failure. There are several kinds. One is inevitable: the failing of organs leading to death. Everyone fails in this regard. I suppose it is the manner of living, style, and health before that defines whether death is a failure or the end of a good life. Failure of health is bad. It's important to take care of health. It's the most important thing there is.
Another kind of failure is failure of judgment. We've all had them. These are mistakes, failure to see the train coming at you. Looking back, they are usually pretty stupid in hindsight, but very hard to see in real time. If you learn from them and grow, and let them go, they won't ruin your life.
That brings up the next type of failure. Failures in a career, a marriage, a relationship, a friendship, an investment, or a business are serious and not easily overcome. More than one is very bad. Sure Ray Kroc overcame failure dozens of times, but most cannot. The odd thing is that some people don't see why they failed. They don't see what they did caused their failure. This is the bottom half that thinks they are better than most, the rationalizers.
I look back on my failures and see they are from personal defects. I can only try to work around the defects. I'm not sure its possible to correct personal defects even if you recognize them.

Here are the three most important things I've learned from you and the DailySpec.
1. Count. Then count some more. If you see something you think is promising, capture it in a statistical test and see–first hand–how correlated it is with what you already know and how much variance in prospective price change it truly accounts for. There is no better antidote for overconfidence bias (and no better stimulus for humility, objectivity, and perspective) than to rigorously test one's ideas.
2. Explore. What you observe in nature, human events, music, and so many other facets of life can teach you a great deal about people and markets. Some of the best market inspirations come from being away from markets and absorbing wisdom from insightful people, good books, and the arts and sciences.
3. Achieve. Half of life's battle is staying young-hearted and benevolent in spirit. There is no better barometer of a person's sense of life than seeing his or her emotional response to great achievement. Being young hearted means staying inspired and always pursuing new vistas. It means reveling in the best of others and thereby fueling the best within us.

I believe that most of us including me, consider Brett one of the most sagacious personages we've ever had contact with. He says explore exploring "what you observe in nature, human events, music, and so many other facets of life can teach you a great deal about people and markets. Some of the best market inspirations come from being away from markets and absorbing wisdom from insightful people, good books, and the arts and sciences."
I thought it might be useful to explore if there are some things we learn from sports that might be useful in markets. I have some ideas along these lines like offense wins the game more than defense. The home team always wins. The first blow is half the battle. Wins by a few points are not indicative of future success. The lucky shots and lucky wins tend to reverse. The end of the game tells the form. Slow and steady wins the game. The horses change at the beginning of new season. Start young if you wish to achieve mastery. Don't play your opponent's best game. You can't run with the hounds and play with the foxes. I haven't quantified many of these ideas, but some I have. But Brett seems to imply that big ideas even when not quantified (perhaps the counting can come later ) can be useful. I'd like to hear if any of you have ideas from sports helpful for markets, (other than that Smith and Antoni are the curses from the Bad One).

Focus on developing a good base of fundamentals(trading principles/methodology) and follow them, gimmicks and tricks will only go so far at higher levels.
Play to your strengths, don't trade others ideas or positions.
Longevity and being able to stay in the game is key, you can't win if you are ejected from the game.
Maintain balance, overreaching and thinking you can master many markets often spreads one too thin.
Cross market feedback mechanisms(how does a slowdown in China impact Brazil, etc.), skills in one sport are often complementary to others.
Discipline and routine, when this change it is all too easy get off track.

1. Big waves come in sets, and rarely is the first the biggest. Never take the first wave.
2. Trust your board. Stay on it as long as you can. Riding until the end of the wave is the safest exit.
Risk is when things might go wrong or get worse. News often focuses on the possibility that things might get worse. People ask, aren't you afraid of getting killed? But things might get better.
A few days ago there were big waves in the 15 foot range. Upon arriving at the beach it was windy, cold and bumpy and rainy. I really had to drag myself into the water. When I got out into the line up conditions were terrible. Just me and my neighbor Alistair were out in the water. But then all of a sudden the wind died down, the rain stopped, and the waves started lining up real nice. There we were, just two of out in these really nice big waves. I love when that happens.
I watch the weather and wave reports and know when a good swell is about to hit. It's really a good feeling to go out when no one is out, and just as you get there the big swell hits.
It's a similar feeling when the market is tanking, things look might grim and you jump in, and lo and behold, things turn around. It's great to be in early.
In the big picture, old people say they regret the things they didn't do the most. It's important to jump in. Life is fragile. Drink deep while you can.

100 in Dollar Yen on approach… it doesn't get much bigger or fat cat than that. You can almost feel the price, like a train track, buckling and stressing under the midday sun as it approaches. It may take NFP to decide that one.
I'm learning a new song by the Beatles called Dear Prudence off the White Album. Its an extremely difficult song to play with interesting changes in time signatures and drum beats over the same meter. Some of John and Paul's harmonies are very difficult to hear on the record so I have to resort to deciphering the chart which is in musical notation form and play the notes for the back up singers to sing in harmony. I'm sure Laurel could sight read it, and like reading a book she can "hear" the melody, notes and harmony just from sight. I haven't read music since 7th grade and deciphering the notes is a laborious process in which I've made a "key" of the notes with the names written out up and down the staff so I can translate them to the guitar. Its similar to counting with fingers. Yes, its very primitive. However, its unlocked some problems in figuring out the song and allowed a break through of sorts. You know how when you read a book you don't struggle with letters and sounding out words, you just fly through it and see and hear the characters in living color, not seeing the black and white. Some people can read music like that on sight, and hear the melodies and harmonies. Remember the movie, Amadeus, and the scene where Salieri is reading Mozart's score and "hears" the sublime music in his head.
Chair wrote and filmed about the similarities between music, notation, and price history charts. Music has discontinuities, jumps that give dynamism, chords. Price charts also have gaps, jumps, air drops. Music has rhythm changes and meter and time signatures. Do multiple markets, such as bonds and equities have chords for their various relationships? Financial markets appear to have rhythm changes. I wonder if they could be classified as to meter and time signatures. The exchanges designate fast markets which operate under different rules. There could be others such as the meter of the open, the slowness in midday, the jumpiness of the close. An interesting thing about notation is that is does not capture rhythm or feel. That is left to notes and interpretation. For example beats such as the shuffle, straight beats, appear the same in notation. I believe also that one cannot copyright rhythm. That's interesting that European notation does not capture one of the main elements of the music. There are similar rhythmical things that price charts also fail to record. The information in time and sales does not appear in regular interval time price charts. Price charts capture price change, but not the rhythm at a single price.
At the Shanghai parks, thousands of Asian women sit with posters behind them advertising their college educated girls' availability for marriage. The girls seem to be in a minority in the population because of the one boy syndrome so they have a competitive edge but they are too busy with the exams and too shy to meet to have a good chance of marriage. The prices in China for American goods seem a bit higher than they are in the US for the comparable goods.
Prices in China seems slightly lower than in the US. The McDonalds Big Mac costs 4 $ or so. And the meal comes to $ 8. To the extent that China has benefited from low prices and low wages in the past, and this has been their model to grow, aside from spinning off the state owned businesses to members of the party, they would seem to have a damper on the growth.
The Chinese 30 and unders like to wear the kinds of clothes that 12 and under wear here with frills and ribbons and lace and sequins. The % of women wearing high heels is about 5 times higher than in the US. Of course, the skyline in Shanghai and the number of skyscrapers on the Bund and the number of good restaurants there easily dwarfs by 3 or 4 fold the comparables in NY.
All the restaurants are twice as busy in China as New York as the space is cramped at home, and it is traditional to have the family and friends dinners at restaurants.
All this talk about the smoking and pollution in China is terribly exaggerated. There are numerous parks in Shanghai and the air there is just as good as anywhere in New York. The % of smokers in Shanghai would seem to have been well below 10%. The prices of sushi in Japan seem to be about 1/50 at the fish market and the fish stores in the fishing villages as what one would pay in New York. And of course there is no freezing and the taste is much better. Had more abalone there in a week than in the US in the last 50 years, and much better.
The competitive economy in Japan seems to be riddled by duopoly, oligopolies, unneeded distribution, and layers of the old boy network. My very entrepreneurial brother in law has been there 30 years and had dozens of entrepreneurial ventures, and each is blocked at the end by an old boy network or extra level of distribution that has to be overcome. Of course, in his defense, he has a great entertainment business based in Kobe, and that was knocked off the block by the earthquake.
The plight of women in Japan is somewhat saddening as they have to be overly subservient, and they do not seem to have much opportunity for advancement to the upper levels of success.
A haircut in Japan is a major adventure as you need 5 or 6 hair cutters to cut your eyebrows and hair, and the good one forbid the facial and neck hairs. That is typical of everything else in this stratified society. But everything works much better in Japan than in the US. There is nothing that would not fix their economy and make it thrive a thousand times better than the US that open immigration would not cure. While I was there, they seemed to be adopting a much more open view towards letting skilled immigrants in than the US policy of closing down the businesses with illegals making the minimum wage.
Of course things are so much more harmonious in Japan than the US with no honking of horns, no dirt on the street, no garbage cans because people are so neat, and everyone trying to do a good job. Throughout the Chinese economy one sees pockets of amazing activity e.g Hagen Daaz in every corner, but it turns out that these have to a large extent been delivered and granted and licensed to high ranking members of the party.
Much of the woes and obstacles to a dynamic society in Japan and China come from the examination system where a very small number of students get into the best schools and everyone has to study 120 hours a week for the exams until they are 12 or 15 and has no time for anything like innovation.
There is about 1% as much physical activity like jogging in Japan as in the US but in China all the parks have thousands exercising in the morning whereas in Japan there is hardly any.
Mr. Leo Jia performed admirably in facilitating all aspects of the trip for Aubrey, Laurel, Susan, me, and Victoria and Artie, and Mr. David Cole was totally beneficent in Japan.
Worth the time and price of a trip to Japan in and of itself is a meal at Hayashiya in Hyago port in Kobe city on Awaji Island. Magnificent shell fish and tuna and yellow tail and sea urchin and white fish fresh off the boats for a meal that would cost perhaps $ 12,000 at Nobu or Masa but for $ 300. And of course nothing frozen or delayed 10 days.
The monkeys in Kobe are behaved just as well as the Japanese. I gave them a few tests on using tools and they lived up to their names (they were the first to discover how to wash bananas and pass it on) when they used a broom to sweep the apples I placed away from them down an inclined plane to get their food.
The one untoward incident I had was when I was chased away by a guard with a cudgel waving after me after I mistakenly walked a few steps into the Eastern part of the Imperial Garden. It is amazing to see the wealth of the shoguns in Kobe and the castles and parks that they maintained.
The Japanese respect for their elders is somewhat harmful to their economy as they can't be thrown out until they are 80 and this reduced the flexible turnover and new blood necessary to compete in a competitive economy.
The traditional Keirutso dining in Kyoto has much to do with tradition and face. We ate in the highest restaurant on a mountain with the water down to all the other restaurants about 30 in a row. Like Ishmael who liked to get the first draft of wind, the best restaurants like to have their water flow down to the others, and this applies to the way they hang their laundry also, with the senior patriarchs hanging their clothes out above the others.
John and Rosanna Floyd are can do harmonious travel companions that made the whole trip even more harmonious than would have been possible to imagine and Susan and I and my family thank them. Amazingly, the last things said to each other was "where are we going next year?" after 10 days of togetherness and encumbrance by me.
Jim Sogi comments:
The observation that women are subservient is an illusion. They only appear to be subservient in public face. The reality is that women control the home and most of the men in Japan and are tigers, dragon women. Don't be fooled.
Some guys blend, I juice.
Just got a new Jack Lalanne Juicer and have been juicing apples, beets, carrots, pineapples, grapes, green beans, chard, celery, grapefruit, oranges, strawberries.
It seems very healthy to drink the live uncooked juice.
The V8 vegetable juice with some tabasco and worcestershire is good.
The fruit juices with a little ginger kicks it up a notch. Juicing adds more variety than just smoothies.
The juicer is pretty easy to clean and was inexpensive.

In old England, disputes were solved by trial by combat with the winner winning the dispute. Modern trial and interrogation techniques put the subject under stress to ferret out weaknesses in the story line. Markets put their participants under stress to determine what is the proper price at the close. A trader who has an opinion will put on a position, and if he thinks its correct will hold that even when put under stress. He holds a belief that the price will be bettered. If his belief is not strong, individually and in aggregate, the price level will not hold, as the belief in the value of the asset at the price level is not strong enough either rationally or emotionally to withstand the stress. Also, if the bet exceed the trader's ability to hold margin, the price will not hold, as the belief is not support by adequate fundamental financial ability. As the market moves, this dynamic works to determine the proper price for the day.
Complicated things of high quality don't just break down in a big cataclysm. Take a modern car. They are well built. The engine will last for half a million miles if properly maintained. However it is the little things that start breaking: the plastic ashtray falls out, the rubber seals wear, the bearing start getting loose, the fabric tears. These little things can get more serious. If the seal leaks, and the oil is low, the engine can wear prematurely. The shocks wear, and the ball joints go. The steering gets loose. Small things can lead to bigger problems. Take a modern city, like New York in the 70s. First it's some graffitti, then some broken windows, soon vagrants move in, garbage piles up and the city head to bankruptcy. It's the small things first. Take a huge economy like the US. The GDP isn't going to fall apart. Employment probably won't go off a cliff. It's going to be small things first. Take a corporation. The earning won't collapse right off. It will be receivables up, inventory up, sales down, or even smaller things. Maintenance up, or down. Take a market like the Nasdaq.
Leo Jia writes:
These are very insightful. Our bodies are about the same. And while the destruction process happens this way, it is interesting to note the creation process is also quite like this. First, small trivial things get created, then the large more significant things. All things seem to move like this in circles. Bubbles start small, grow big, then shrink a little, then burst.
Jim Lackey adds:
Hold on ther' hoss. The first thing we do, it wash, feed and stable the horses before the cowboys. This car post caught my eye. If the simplest part breaks, a mass air flow sensor, the engine runs rich and bad things happen. Yet we have a dummy light! Even back in the day we had dummy lights for high temp, or low oil pressure. These little 25-200 dollar parts break on brand new machines. Take the worn out 100k 7 year old car. Yes what you say is true. 35 years ago the 100k car may be dead in the crusher for scrap. Today what people thing of the heart of the car is the engine. With CNC , CAD and CAM all short for, computers do not have UAW contract for, tired nor sick nor go out of whack and slap together the last V-8 at the end of bowling night. Therefore the engines are designed and build and installed to Engineer spec. They do last for 250k. Most but not all of them do 250k except for the short cut copy cat Far East red flag waiving commies BYD my 6.
The little things that are build to spec yet cant possibly last for 7-12 years as you say rubber O rings, Balls joints, tie rod end,s brake rotors struts all must be changed or maintained. The most complex and weakest link of the chain on new cars is automatic transmissions. I made one the of the worst mistakes trading this week. I was taught about racing cars bikes and anything with an engine, failures. In a way we kept track of the max min wait time on a failure of a part. We change them at or before the median failure time. I forgot all about that for our trading. Didn't lose, it was much worse than that to a racer not winning is as painful as being on fire.
One spec posted a customer service report on cars and diamonds weeks ago. The gist was one man said change all parts. The other man said wait 5,000 miles. The implication was the second man said wait, and was best. What wasn't taken into account was two things. The performance of the car and his safety and time of a second trip to the shop. Other was the parts probably were not in stock at dealer B. There fore the guy simply told what most want to hear, no money today rather than we will have to keep your car over night as the parts are coming off the ship from Japan.
The discussion also goes to medical. too much of medicine is based on illness. When talking to my Docs and their ranges for normal I burst out and said, your kidding right? How do basic stats escape Medical training? How much better can we all feel if we did X and Y do the the people all wait until a breakdown and see the Doc for solution which prescribed as X. I know why. I did the same thing last week on my trading. I didn't consider wellness. I was waiting for the market to become sick then do trade X. My trading doc even warned me and kept me from having a bad loss. He was focused on wellness ( is best I can describe) I was looking for the illness. (Okay so the markets went 1530 to 1490 and I said why not wait for 1475 to come in? I pull my racing pits cap over my head and tell the wife, at least I didn't lose short)
How much better will a car perform with New tires brakes and rotors vs a car with 5,000 miles of anecdotal testimony to wait. I can give you the stats on new vs 20k or 40k miles and after one race on a real car. Racers change brakes and tires after each and every weekend. We rebuild engines most every weekend depending on class. In some pro classes we rebuilt engines after every single 1/4 mile run, new pistons, rods and bearings, Valve sprints and retainers, all seals and gaskets.
What the anecdote above states is the engine will run for 250,000 so then to should the car. Yet the car will not move with a broken ball joint. The engine will die with a broken timing belt and over heat with a bad water pump, that now last to 110,000 miles. So the engine system is still only good to run for 110,000 miles. The trans and rear end gears all die at 125-150 and the fuel pumps and all do the same. The catalytic converters die way before this. Most cars have a 5 year 100,000 mile warranty on the drive train. Its only 3/36 or 5/50k on bumper to bumper.. The emission control systems or parts are now only good for 80,000 miles.
So in theory your car is now worse than a 1969 model. It will break down and be non drive able 20,000 miles before the 1969 model died and went to the crusher. Yet your correct, at 80k miles your car will be fixed for 1,000 bucks and in 69 you needed a new engine trans and every hose belt and switch was dead.
This entire deal of failures was burned into my trading memory banks for life. I used it in some ad hoc way since MR Vic showed me in 2004. Yet the advances in his technology on how to quickly repair the trading engine and have it on the road to profitability was lacking by lackey.
The story I wrote about my teenager failing to appreciate the need for trans fluid made me dump the BMX van for 25% above scrap rates to a new friend. I am now shopping for a good used van. There is also a meme on pricing of used vs new cars. We try not use never always when it comes to life. Yet the financial advice out there has man a never and always do.
Too many men are all over the past 10 year return of stock at or about nil. The we are in a range trader calls have been falsified many times this decade. The SPU made a high in 07 the Russel or what ever made a high this year. Yet its true and maybe always is tr that not all stocks make a new high as the joke is many stocks fail to exist, survivor ship bias. Its all mumbo as they use all or this or that index.
Then to say all new cars have engines that run to 250k miles and do not fall apart all at once.. is also false. A brand new car has the ability to shit down or go into safe mode. Its broken according to our ladies who drive. It can only be idled at 35mph to your local shop. With palladium and platinum are such high prices the emission control systems are too expensive. The cars heart is not the engine, it never was the brain. It used to be the driver and the mechanic. Now its a computer. We have fire trucks that will not start if the diesel engines emission system is on soot burn mode.
Now we have computers in control of making markets for the global stock and futures markets. All economic reality seems to be lost in the short term. If political hack from Berlin says A and EU hack said confirm A and US is about to have a press conference you can forget about the next four hours prices being predictive. The markets computers go into safe mode. They will move and shut down quickly and we must, as traders idle at 35 MPH to our local dealer of data to find out what happens next after that part failure.
For what ever reasons I have gained my passion for markets back. Of course we know where we lost it. What makes men take risk? What makes risk takers skip a generation? Is that true? I had a friend as me this week about becoming a spec. I asked him to answer this one question. Would you rather trade your money and take risk per 500k account to eeke out a living or use another mans money and take 20% of profits yet no fees? I have asked this Q so many times and it reveals much about a mans capacity to take risk, yet most important to take pain. Ya see racers, we do not care about losing crashing or getting hurt. Its part of the game. We do not like losing, yet not winning that is so painful, like I said we wear fire suits and not winning is as bad as completely destroying your car on driver error and being on fire.
The gist of the answer is if your rather trad OPM you do not belong in the hours 1/2 day markets, ever. Do not do it..It has to be the hardest way to make a living. The easiest way if you have any capacity to sell or raise money is ride the tides and collect a fee. I am sure you can find a way to make a firm stand on the middle ground. Some fine research and pick some fine stocks and short some over plus commodities after the bubble has been busted and hold that roll that for years. Now you have the ability to take down a small fee and a profit incentive.
What has changed my attitude is being certain about one thing. These markets change direction and patterns change so quickly its fast, like racing and Fun! Where in the hades have I been the past few years not to look at all of this as a positive thing for, me. I love to go fast. lack
My motivational quotes for this week attached.
August 1908 issue of a periodical for bicyclists called "Bassett's Scrap Book". A short item contrasted the modern age to ancient times and presented a variation of the epigraph:
"Naram Sin, 5000 B.C. We have fallen upon evil times, the world has waxed old and wicked. Politics are very corrupt. Children are no longer respectful to their elders. Each man wants to make himself conspicuous and write a book."Johnson's often-quoted definition of genius, "the infinite capacity for taking pains."
"genius is inspiration, talent and perspiration." Kate Sanborn
The President of the Old Speculator's Club, Jack Tierney, writes:
I seem to recall the name
Carnegie's "Gospel of Wealth" idea took his peers by storm at the very moment the great school transformation began—the idea that the wealthy owed society a duty to take over everything in the public interest, was an uncanny echo of Carnegie's experience as a boy watching the elite establishment of Britain and the teachings of its state religion…Since Aristotle, thinkers have understood that work is the vital theater of self-knowledge. Schooling in concert with a controlled workplace is the most effective way to foreclose the development of imagination ever devised. But where did these radical doctrines of true belief come from? Who spread them? We get at least part of the answer from the tantalizing clue Walt Whitman left when he said "only Hegel is fit for America." Hegel was the protean Prussian philosopher capable of shaping Karl Marx on one hand and J.P. Morgan on the other; the man who taught a generation of prominent Americans that history itself could be controlled by the deliberate provoking of crises. Carnegie used his own considerable influence to keep this expatriate New England Hegelian the U.S. Commissioner of Education for sixteen years, long enough to set the stage for an era of "scientific management" (or "Fordism" as the Soviets called it) in American schooling. Long enough to bring about the rise of the multilayered school bureaucracy. But it would be a huge mistake to regard Harris and other true believers as merely tools of business interests; what they were about was the creation of a modern living faith to replace the Christian one which had died for them. It was their good fortune to live at precisely the moment when the dreamers of the empire of business (to use emperor Carnegie's label) for an Anglo-American world state were beginning to consider worldwide schooling as the most direct route to that destination.
Mr. Krisrock writes:
This happens when there is a world price for labor…that American foundations arranged for 100 years.
Jack Tierney responds:
I'll go along with the parts played by American foundations, but not the 100 years. In a recent book by David Horowitz, "The New Leviathan," he points out that many of the great foundations we still hear so much about have wandered substantially from the goals envisioned by their founders.
Among them are the Ford and Rockefeller foundations, as well as those of Pew and John MacArthur. Each accumulated substantial fortunes in very capitalistic endeavors…and expected their trusts to continue to promote efforts in that direction.
At first this worked as the initial appointed trustees were chosen by the benefactor. Over the years, however, (and this relates to my initial post) subsequent trustees went off in their own, very contrary direction. inevitably, they labeled these modifications as "progressive," a catchall phrase that seems to excuse almost any perversion of original intent.
Most of these changes in direction have occurred over the last 50 years as the original trustees passed away or retired. Only Olin was prescient enough to "sunset" his trust to forestall this drift.
Lefevre in Reminisces, and Clews in Fifty Years recount manipulators buying up a market and then selling it at the top, toppling the market. Yesterday's market (2/28) felt like that– a quick, too quick, buy up, and then a big fall at the end, dashing some hopes surely. I wonder if such a thing is still possible in today's markets. A 10B line swings some weight.
I'm in Valdez Alaska. It snowed 2 feet the day before I got, here, and 3 feet the day I got here, and 2 feet today, and it's still snowing. When backcountry skiing, avoiding avalanches is a constant concern and a matter of life and death. I've talked to a few real experts on the subject here, Dean Cummings, former World Extreme Ski 2nd place champion and owner of H2O Heli ski, and Matt Kinney.
One of the basic ways to understand the snowpack and the potential danger of avalanches is to dig a pit in the snow and examine the layers of snow over the season and test its structural properties. Snow, when viewed cut away in a pit, shows the layers of snow over the season like the rings of a tree, exposing the various attributes of the snow. One of the things to look for is a weak layer in the snow, such as a layer of ice formed by rain or sun melt, or powdery sugar snow called hoar frost. The other thing to look for is slab formation caused by wind blown snow. The danger is when a slab slides on a layer of ice, or sugarlike snow and forms an avalanche.
The pit exposes the layers and the skiier examines each layer by touching it to feel its consistency. The skiier then isolates a 1 or two foot wide column of snow which can be 240 cm tall where that is the depth of the snow. After tapping the top and counting the number of taps, if the column of snow collapses at the icy or sugary layer, it is a sign of weakness in the snow, a potential place where an avalanche might trigger at the weak layer in the snow structure. Avalanche experts use microscopes and examine the snow crystals and see how they have metamorphed over time with temperature. A pit is only a snap shot of the snow in one area of the mountain and the snow cannot be assumed to be the same elsewhere, but it gives information about the relationship of the layers.
I could not help to think of the similarities in the historical evidence of snow to the order book. I wish one could look to see the structure of the entire order book up and down the prices. Especially nowadays with computer traders, the order book rapidly and constantly changes, but there would be information in the changes in the order book. There would be weak layers, or strong layers in the book. There may be structures in the order book near or around round numbers, and in time around announcements, closings. Even better would be to see whose orders there were. I've read that CME full members can see the tags identifying the order makers' identites. I'm sure the complete order book is available to someone somewhere, perhaps the market makers see this. Without the information it feels like flying blind sometimes. It certainly would be an advantage.
Have you guys heard about this guy:
"Hawaiian big-wave surfer Garrett McNamara will go to any lengths to chase a massive swell. On Monday that pursuit took him back to Praia do Norte, a tiny coastal village about 60 miles north of Lisbon, Portugal, where he got pulled into a massive wave that has the entire surfing world in awe. "
youtube video of him at Nazare, Portugal
Could the surfing aficionados please explain to me how these people do not die?
Jim Sogi responds:
Scott, First they train and train and train so they are prepared. They have a system with the sled driver so they can get rescued if they fall. The maximum hold down would be 20 seconds for one wave, and possibly 40 seconds for a two wave hold down. With training one can hold their breath that long fairly easily. A three wave hold down for 60 seconds gets dicey and black out is possible. Thirdly, they are wearing life preservers that float them to the surface. Shane Dorian has also developed an air bag that inflates to bring the surfer to the surface. The statistics of surfing demonstrate it is rather safe overall.
New Years eve brought the biggest best waves of the year to Kona. In the morning it was triple over head, clear blue sky, perfect shape, completely glass on the water without a breath of wind, and only a handful of friends out. It doesn't get any better. That afternoon the waves got even bigger. Just before I went out a huge wave cleaned out the entire line up and washed people on to the rocks. They got out with white faces and minor injuries. I had a perfect day where I did not fall once, did not get caught inside and caught each wave perfectly and rode it to the end. All in all a very rare day, one to remember for a lifetime.
Lack recently wrote about not making any errors. My son used to play Mortal Kombat video game as a kid and when he beat the opponent without suffering a single injury it was a perfect fight. It's the kind of day when you enter perfectly at the bottom tick and your bid is taken in size, and it immediately starts up, you ride it all the way and exit right at the top. For some reason it's not the kind of thing you can do at will, nor does it happen all the time. I had been training so felt strong, and there had been waves for the prior two weeks. Mentally I felt good. I wish I knew the secret to achieving such good results with more consistency.
Jeff Watson comments:
The key sentences, "I had been training, so felt strong, and there had been waves for the prior two weeks. Mentally I felt good. I wish I knew the secret to achieving such good results with more consistency."
Well played Sogi San. And you answered your own question.
Meanwhile our waves have been thigh to waist high and the SUP has been getting the workout, not my 9'6" or fish or any other board in between. It's really a drag living on the pond of the Gulf of Mexico.
Craig Mee writes:
Sounds great Jim, good job indeed.
Having a consistent plan before you paddled out, and it seems conditions were relatively steady, probably allowed for a strong take off with commitment each time. Finally, as you felt comfortable, you were probably more likely to squeeze each wave for everything it was worth. Your day, your market, your result– excellent.
Recent conversations with a close friend have had me thinking about "The Basics". How, and to what extent, does an understanding and focus on the basics of a particular subject contribute to the building of a strong foundation from which to expand outward in a stable and progressive manner? While they may never be mastered, an understanding of what the basics are seems to apply to a myriad areas of life. The foundation in the basics in various areas of life's pursuits would seem to provide the base from which to advance. Conversely, lacking such a core likely limits movement forward relative to one might be able to go.
In sport we might learn the basics on the very first day of study. In traditional Japanese karate the student often begins with the making of a fist and the punch. The simple mechanics are improved upon and practiced in every training session from white belt to 10th dan black belt. In fencing experts say that basic footwork is 65% of the game. In mountaineering one is told of the importance of keeping one foot moving after the other and not stopping too often to rest.
In nature the basics of survival and expansion can be seen in both plants and animals. Sequoia Giganteum, the giant sequoia, manages to live several thousand year through thick bark that protects against fires and pests amongst other factors.
In relationships the basics of simple greetings and compliments by name and eye contact seem to go far.
In games like chess the building of a solid foundation and harmony amongst pieces goes a lot further than memorizing openings.
In civilizations there are often core values that act as a bulwark against more nefarious forces. The founding fathers of the United States had some ideas on this topic. What might be learned about current events and political forces globally and those of say Rome and the British Empire?
In the daily routine the art of breathing properly, stretching, posture, exercise, hygiene, and diet.
In trading the basics might include first the art of survival. Important on the list would also be the daily routine, the size and number of winners versus losers, the ability to evolve with markets yet maintain core principles without style drift amongst many others.
In Japan there is a saying " Ichi Nichi Issho" or "One Day One Lifetime". At the core one might view this as a starting point in the basic building blocks and unfolding of one's life.
Many books could be written about all this topic and this is meant to be only a short list and some thoughts. What other areas and basics might be considered in various endeavors? Who can we look to as examples of success built upon the mastery of the basics? What books or learning tools might be applied and studied?

There will be a lot covered in this topic, but I'll touch on Technical Analysis. Specifically, on what's commonly referred to as "a basing pattern". In 2012, this pattern played out to its best in USD/JPY. The cross has languished in 76-78 yen area just long enough to lull everyone. The technical foundation for a blistering rally thus had been built. Technical Analysts refer to this set-up as "things that stay horizontal the longest — go vertical the fastest"
Jim Sogi comments:
The myth is the "basics" are easy. The 10th Dan karate master still studies the basic punch because there is so much depth to it, the timing, the placement, the purpose. Musashi Miyamoto after a lifetime of study of the sword still pondered the basic sword cut and the purpose of it. Basic diet sounds simple, but eating and cooking properly with nice taste and presentation everyday is very very hard. Breathing sounds easy and everyone does it, but to breath with the right mindset can be the key to nirvana. Talking sounds easy and everyone does it, but to say the right things…well you get my point. Real mastery of the basics, especially at the highest levels, is difficult.
Premium Rush is a great movie about fixie bicycle delivery riders in NYC delivering a ticket with a bad cop trying to steal it. The greatest part is the "what if" scenarios in choosing his bike route through traffic. Very fun movie, good riding, fast paced, not much violence, exciting, ok plot (mostly a chase).
Jeff's coin proposition bet illustrates a nice lesson for me when applied to trading. That is, even if probability is favorable, there can and will be streaks against. So, there needs sufficient N and staying power for probability to work in trading. So all the seasonal or studies that trade once or twice a year probably don't have a statistical edge.
The inverse lesson is that sometimes it is good not to trade when the probability is not in favorable, as in never take a proposition bet against a Florida surfer with a low handicap, (humor intended).

I read that in a sample of 10^10 binomial chances, there can be a run of a 1 million 1's.
The idea that in an infinite random time series every possibility will occur, such as the history of the earth, kind of worries me. There seem to be laws of nature, but are they? Will they change? Do they?
Ralph Vince writes:
Yes, and it is man's innate ability to asses such probabilities (and hence, the fallacy of Huygens and Pascal — that risks should be assessed based on mathematical expectation) that is the most fascinating thing about the entire story of evolution (again, to me).
Why do you get on an airplane when it can crash? Why do you get in your car and go out to buy a quart of milk? We have evolved over eons to pursue often time-critical rewards on a risk-laden planet — it IS how we operate or we would be still cowering agoraphobically in the shadows of a primeval world. This notion fascinated me (and the reason I wrote a book on it in 2011), and the more I dove into it, the more I saw that the answer to it — i.e . the fundamental equations we posses innately for assessing risk, pertains to all other mathematical decision (game theory is rife with concepts that are tuned to the Huygens/Pascal model, not our innate model) and ought to be reassessed under the lens of our superior, realistic model (and yes, it is superior, or we would all be looking for termites to eat up in a tree some place.
Leo Jia writes:
Your notion about man's innate ability to assess probabilities is fascinating to me. I hope to read your new book soon (I presume it is Risk-Opportunity Analysis.)
It is clearly phenomenal that the human species was able to advance over other species. It is not as clear though whether it was man's special innate ability that made man evolve or it was the evolution process that gave man the innate abilities. Regardless of whatever came first, I think many of man's innate abilities that exist today were largely fostered by the evolution process. While this was wonderful, it is perhaps also very discomforting to learn that many of our innate abilities were more meant for the environment of the wild, not really for the modern times as the modern couple hundred years is far too short in evolution terms. It begs the question of what of the very innate abilities are really useful and what are not. Whether we realize what abilities we have or not perhaps is not a big issue as we naturally use them in life. It does become more important for us to know what of our innate abilities are actually harmful to ourselves today.
Leo Jia adds:
I did a test. It went like this:
1) toss a coin 10 times,
2) if there is 5 heads then add 1 to a record do the above 2 steps 1 million times.
The chance that in ten tosses one gets exactly 5 heads and 5 tails is 24.5539%.
To be more comprehensive with the test results:
4 heads and 6 tails: 20.4194%
6 heads and 4 tails: 20.5125%
3 heads and 7 tails: 11.7019%
7 heads and 3 tails: 11.7010%
2 heads and 8 tails: 4.4018%
8 heads and 2 tails: 4.4145%
1 heads and 9 tails: 0.9783%
9 heads and 1 tails: 0.9830%
0 heads and 10 tails: 0.1004%
10 heads and 0 tails: 0.0968%

Thank you, gentlemen. This is good info to ponder and apply to trading. For my part, I found a shiny Lincoln-cent and spun it 10 times. Result: 7 heads.
Jeff Watson writes:
But there is also another trick of spinning a coin very fast, get down to coin level on the table and observe carefully, and if you get a blurring image of tails, call tails…same thing if you see heads, call heads. Since the coin spins at a slight angle, the side that you can see the image will be what lands.
Ralph Vince adds:
As far as coin tosses and trading — and this may be redundant information to many of you — to me, personally (in my sciatica and failing vision nowadays) I find the largest implication pertains to the nature of the equity curve and expectations, and the deceiving nature of randomness.
We know if we plot out the equity curve of consecutive coin tosses (with heads +1, and tails, -1, say) and we plot this out, we can then draw bands around the mean expected value (0 in this case) of standard deviations. Thus, we can draw a one standard deviation band above and below.
Such a band will be parabolic, like a parabola resting on its side, rightward-facing, opeining up as time or trades or plays go by. That is, the upper band will always be ever increasing albeit at an ever decreasing rate. Thus. to be ahead of the expectation by play number X to the tune of 1 standard deviation, is below being ahead of the expectation by play X+1 or X + N where N is any positive number.
Couple this now with the Second Arc Sine Law*, which pertains to such randomly-generated equity streams and tells us (the essence of The Second Arc Sine Law) that we would expect both the peak and nadir of equity stream to occur least likely towards the center (time-wise) and most likely near the start or finish of such a stream.
These two principles, take together, warn us that in a stream of randomly-generated outcomes (coin tosses, or trading if/when the outcomes occur with randomness) we should expect the rightmost endpoint to be at or near the very top (or bottom) of the entire equity run, deluding us into conclusions, "This works!" or "This fails," that have no basis in a causal existence, but are merely the artefacts of randomness.
*The First Arc Sine Law buttresses this further, this law being that we should expect the ratio of the cumulative equity line (comprised of X number of plays) least likely to be above the expectation X/2 number of times, and most likely to be above or below X or ) number of times — the same Arc Sine distribution as the Second Law. Thus, say, if I toss a coin ten times, it has an expectation of 0 (given the caveats mentioned in this thread!) and I would expect with highest probability that ten of those tosses see the cumulative equity line above (or below) the expectation line of 0 and with the least probability, see 50% of them above and below the expectation (0) line.
As with many news events, the market's reaction is not always what one expects. The reason is that the predictor's assumptions may be wrong, or the wrong premise is being held. In the current election, it appears it is not the substantive political positions that matter, rather it's the certainty or uncertainty of the outcome.

Perfectionists have a compulsion to do things perfectly. When things do get done, they are done well, but there is a dark side. They can't get things done because they are never perfect. They seem afraid to take risks because they are afraid of not being perfect. They have many requirements, so many that needed projects do not even get started.
Trading is one of those non perfect endeavors which when done well has a high, say, 40%, failure rate. This is tough on perfectionists.
A friend is a great singer, but as a perfectionist refuses to sing because it's not perfect. Singing is like trading, you never hit the exact note. In fact that is the beauty of the human voice, it's not perfect. It's the wavering and straining that makes it emotional and beautiful. But that is another topic, similar to the penumbral idea.
In Swahili, mzungu (wazungu-pl) is the name for white people and literally translated is one who wanders around aimlessly. It is a good description of the the today's market — wandering around aimlessly. It is at a border crossing, 1400, so there may be some rhyme to the reason.
I recently read the wiki page about The Endowment Effect.
Basically, it says the one values his possession much more than others value it.
Thaler conducted the following experiment. He randomly gave some participants a mug, which sells for $6 in a store. He then asked the ones now owning the mug to give a minimum price below which they would not sell the mug, and asked the ones not having the mug to give a maximum price above which they would not buy the mug. It turns out that the owners valued it for $5.25, while the bidders valued it at $2.75. He concluded that the very fact that the persons owned the mug made them give it a higher value.
Very interesting research. But I wonder if the conclusion is as that simple.
First, I wonder what would happen if the owners were asked to buy another mug. How would they now value it? Since it is not a critical item to have and they already own one, it is reasonable to believe that they would bid an even lower price than the bids from those who didn't own it, isn't it?
Second, what about selling short is allowed in the experiment? If the people who didn't own the mug were asked to price it if they would sell it short. I bet their price would be even higher than what the owners offered, and very likely be higher than the $6 store price.
Any input on this, please?

Leo, I'm not sure it's productive to attempt to extend these "effects", and there are many of them, beyond their original definition without doing actual experiments. This particular effect seems to be as simple as "defend what's yours harder than you would attempt to get the same thing from someone else", one of the ancient evolutionary developments. Primitive (as well as advanced) animals demonstrate the same effect when fighting for territory, that's why the challenger loses most of the times. Of course someone who has a relatively useless (from their original standpoint) mug to begin with doesn't want another one. Personally I find it more interesting to think about the practical value of the original effect. In the behaviorist books it's supposed to manifest itself by "holding on to losers too long". Every time I read this I always think about whether the logical conclusion is that a rational person should always sell "losers". Sometimes they bring up the tax loss effect, and that's fair but it doesn't get to the heart of the matter. Considering this question, and all the robotic trading that goes on, how would one take advantage of this effect?

This is a fascinating subject for exploration. Being only slightly tongue-in-cheek, I wonder what effect negative real interest rates have on the willingness of people to hold onto "junk" ? To the extent that "the cost of carry" (i.e. monthly rental fees) are small, hoarding is a rational behavior. Also, there was an article in the WSJ last week discussing the effects of "clutter" on marriages and home life. Lastly, there may be a "depression-era" and "aging demographic" effect occurring here. In the situations where I've (sadly) had to empty out elderly relative's apartments, I've discovered that depression-era people hoard useless things like return envelopes from bills, archaic car and doorkeys, memorabilia from bygone days, etc. I think that there are many interesting factors at work in this trend — and there is market-related utility in thinking about them.

It's really hard getting rid of one's "junk". There is a weird attachment to the stuff. Its almost painful to throw stuff away. Then there's the issue of getting rid of the junk, and then needing that item the next day. Feng Shui has some good tips on clearing the clutter. There must be some sort of hardwired effect causing one to collect stuff. Look at the bag people pushing around carts of junk.

I'm with you, Jim, and in the tropics, clutter, dirt and smells brings mosquitoes, which is a very good reason to keep things clean.
On a side note. I've had a lot of trouble with mosquitoes, though I went to a friend open air villa the other evening , and when dusk hit, no mosquitoes ? I looked around and put it down to a) everything was white, walls , furniture, coverings, a well cared for garden, two ceiling fans, (some sea breeze) and importantly I thought …lights under the table we were sitting at. ie everything was clean , tidy, and white, with air.
Further, I read once, if you haven't worn clothes for a season, toss them. That's certainly worked for me.
No doubt those who make money in one particular stock , get attached, (you see it)…it clutters their mind, and they will drag any positive out of fundamentals, value, whatever to get back involved. Got to clear the clutter, or put it out of sight, to free the mind.
Rudolf Hauser writes:
In considering the impact of the pure psychological effect on value from ownership, one should not ignore the economic effect. The cost of the purchase is not just the purchase price of the item but the value of all the effort that went into finding the item in the first place and how difficult it might be to be able to buy it again. Then there is the risk of the replacement being defective or other problems in the acquisition thereof that might happen. One also has to consider the potential cost of needing an item and not being able to acquire its replacement in time to meet that need. As an example, I once wanted to buy a new ink eraser to replace the one that wore out. I then found that I had to run around to seemingly countless stores to find this inexpensive item –an effort countless times more expensive in opportunity cost than the price of the item itself. Needless to say, when I finally found the item, I purchased a whole box full to insure that I never would have to spend so much in search costs again for that item. Nor would I have sold those again except for much more than I paid for them.
As for the psychological impact, say one has purchased an object of great beauty at a price that subsequently appreciated considerably. The new higher price might be one at which one would not consider it prudent to buy given the overall state of one's financial resources even though it is an item one might wish one could buy. But already possessing it one has the excuse for buying it via not selling it because one already had done the deed in effect. When an item is not unique or rare and is easily replaced when a new one is needed, one would not suspect that same tendency to value the item in possession more than the same item not in possession. It would be interesting to see if this effect still persists in that case and how it compares to the former.
A stock would be of the latter type at least in small quantities. With larger quantities there is always the uncertainty as to how much such purchases might impact the price, which would the economic reason as opposed to a psychological reason. A psychological reason might be the emotional difficulty of making a decision that one is not anxious to repeat, ignoring the fact that with an investment an implicit decision has to be made every day as to whether to continue to hold or not. The difference is that to sell or purchase is an active decision whereas to hold can be a passive decision. In effect holding is also a way of putting off a decision.
Kona, Hawaii is a small town and usually lags behind the rest of the country in booms and busts. We've had a bad bust here the last few years, but this month was the best month ever for tourism numbers and spending. Looking around the little town is bustling. The increased population is evident in a wider divergence of classes of tourist is notable in more bums and pan handlers who tend to stick out. This leads to the broader conclusion that despite the problems in EU and issues being harped on in news, there is a recovery occurring. I even had an employed carpenter trying to rent. He was one of over 20 applicants at a 20% higher rent for a unit I had trouble renting a few years back.
When the market was touching negative territory last week, it didn't sound right that the year would end up negative. The president and other flexions have too much to lose at this juncture to let it go negative. Plus, there was all the public who bought the spring bull run all going underwater getting cleared out.
Some new research shows that most of the population is below average with a few individuals with outlying performance. Empirical studies of the market display fatter tails than normal and slightly skewed distributions. Anecdotal evidence supports this idea as well. I am wondering how this affects the performance of normal based models.
I am researching and reviewing my contact with hats over a not uneventful life. I am considering their value, their uses, their symbolic significance, the great people I know who have worn them, the hat corporation of America I bought as my first trade, the hat that Tom Wiswell always wore to prevent sunburn and cover up baldness, the hat that Shane wore that made him an icon, the hat that the accountant in Monte Walsh wore that Hat Hendersson just couldn't resist noting was just right for a pistol shot, the hat that I wear now to show my respect for those previous, the man I called Hats H. because he always had a million different conflicts of interest while working for us. The importance of a hat outdoors in the West to shield from rain, sun, and the elements. Et al. What value do you see in hats these days? What anecdotes? They seem to have gone out of style because of the automobile. You don't need protection from the elements any more. Also they're hard to store. How do they relate to markets?

When I graduated high school, the guy who measured my head for my mortar board said, "Young man, I've been doing this for 35 years and you have the biggest head I've ever measured".
As a result of my freakishly large cranium, hats rarely fit me. I wear one from time to time, but only out of necessity, and occasionally for functionality.
Necessity is when I need to keep my bald head from burning in the sun or freezing in the winter or dry in the rain. Never under estimate the insulating and protective qualities of hair.
Functionally is because I need a hat when I hunt to keep the sun out of my eyes when I'm scanning for game, peering through my scope to place the cross-hairs on the shoulder of my intended quarry, or placing the aiming pins of my bow in the middle of said quarries chest cavity.
I avoid hats otherwise as I can rarely get one big enough to fit. If I wear one too long, it gives me a headache. Therefore, when it comes to trading, if you see me placing a trade while wearing hat, fade my position as I'm likely making a losing trade because my mind is clouded by the hat that is squeezing my brain all to tightly.

I think I am fairly well known as a hat person, and have been since I wore unusual chapeaux /to synagogue and school when 12 or 13.
Aside from style and stating an individualistic aspect, I think a hat harks back to a gentler, more mindful age, perhaps 100 years ago. It also keeps the head, inside of which are all these excellent ideas and scenes for a better tomorrow and a niftier evening today, comfy-cozy. Hats also show, oddly enough, respect. Hatless men in the 1970s were declaring their freedom from the mindfulness of suit and hat, and perhaps we are the poorer for having abandoned hats.
They also keep milliners in funds, and milliners I went to grad school with in the early 90s were aghast at the drop in hat-wearing citizens, alleviated only by temporary crazes or fads that fade as swiftly as they arise.
As a biker, for me, even mild days produce a breeze when one is on that leather seat, and a hat prevents sunstroke and sun in one's eyes as well as too much wind over one's head.
In the Orthodox world, wearing a hat connotes one is married, so it may be foolish of me to wear hats, because i communicate a status I do not currently entertain. But i do like the fashion and focus statement being made by wearing a lid, many of which, actually, i create myself.
Finally, one can maintain a superior air of mystery in a hat, which is impossible to the same degree in a hatless state.

The baseball cap trend: rappers wearing the caps askew, wearing caps with logos of designers and companies, wearing caps for status/advertising, caps as gang signal, wearing caps in restaurants/indoors, wearing hoodies in lieu of caps, caps as fashion, caps on backwards, caps with brim curved just so, it all has to do with being cool. Lebron James wears Yankee cap to Indians games–it's all about me, fool.
Gary Phillips writes:
"Wearing a cap backwards is a baseball fan tradition that started with Yankee fans. It wasn't because they liked Yogi Berra, either. The Yankees and Red Sox have a century-old rivalry. A group of young guy Yankee fans, around 1980, took the train up to Boston to catch a couple of games. Boston fans are loud and boo other teams. The young Yankee fans were seated in front of loud Bostonians. The New Yorkers didn't want to start an altercation, but made statement. Those guys turned their Yankee caps around backwards to show the Bostons that they were Yanks fans and proud of it."

It would be nice if this worked in the market. But then the adversary could always tell if you were weak or strong, especialy if signals could be reflected from the hat. I was surprised to see that in all the uses for hats I have collected, including flopping the rump of your horse, and fanning a fire, and collecting water from a stream or the rain, I did not see many variants of using it as a signal to get a cab or alert a Native American that a interloper was near, or to collect bets, or to conceal a salt shaker. This latter is particularly effective in the west because to ask a man to remove his hat is akin to a date with boot hill.
Gary Phillips adds:
Surely not a hat, barely a cap, let us not forget the kippah or yarmulke. The Talmud says that the purpose of wearing a kippah is to remind us God is the Higher Authority over us. He alone is Lord of Lords and King of Kings. When we pray and worship with our heads covered, we are saying that we are in total and complete submission to the will of God Almighty now and forever.
I was recently in the hunt for 2 of the crocheted variety for my 2 and 4 year olds to wear to school. My elder son demanded that the kippah be white with a blue Magen David. The synagogue gift shop was unable to fill our order, so I turned to a higher authority - E-bay. As J. Peterman would say, it is 6" in diameter — one size fits all. Handmade in Israel with a *very small* fine stitch. The yarmulkes are from Israel and are made by people who have made Aliyah; low income and handicap people, generating income to make a living.
I grew up and observant Jew until I had my first taste of bacon and blondes, and I never looked back. However, I now find myself lighting the candles, saying the hamotzi, and making Kiddish on Friday nights… Nice.

A hat is essential in Hawaii to keep off the sun, rain and wind, to keep glare out of your eyes, and at night on the mountain for warmth when it gets cold. There are different hats for different situations. A baseball cap is good all around since it keeps the sun off your face, stores easily, can be worn in a car and is cheap and stays on in a brisk wind. A good brim hat is good to keep the sun and rain off the back and shoulders as well. A nylon hat is light and can be washed. A waterproof rain hat is good for extended rain, and a light nylon brim is good for hot sun. A small brim bucket with a strap is worn in the water while surfing to keep intense sun at bay for hours in the water, and to stay on in the surf. A knit or fleece watch cap is good for boating at night or sleeping in the cold. A helmet is good for sports to protect the skull from boards, rocks, trees and impact. The Original Buff is an adaptable piece that can be worn as a hat, scarf, or facemask. A balaclava is good for winter conditions and can be used as a hat, or face mask in windy conditions. I must have 20 or more hats.
As with all equipment, each type of hat is specialized for specific conditions, and there is not one that is good for all conditions. As with markets, its good to have specialized systems and rules for the differing conditions or cycles and no one rule is good in all conditions but must be tailored to match the expected conditions.

I do not wear a hat indoors with the exception of trains and planes or if there is no good place to put the hat. If there is a draft from air conditioning it helps to keep me from getting a headache. But more important is that unless I just want to hold my hat in my hands there is no good place to put it. I prefer to read, not hold a hat. I once made the mistake of putting a Panama hat in the overhead rack in a plane. The motion of the plane bounced it around enough to ruin it. That gives me little choice but to wear it. If I have a hat without a brim, such as my winter hat, I can a do take it off aside from trains which are not that warm.
Bill Rafter adds:
Glare, particularly from lensed overhead lights or high-hat floodlights can cause headaches and eyestrain. That can easily be counteracted by wearing a baseball cap or other large-brimmed hat indoors. I have kept one at my desk for decades.
For years I noticed that whenever I saw a certain actor & director, he was always wearing a hat, even indoors. Then I saw him entering a food emporium at a ski area and he removed his hat. I immediately understood why he always wore one — his particular baldness aged him at least 10 years. So his vanity choice was either a wig or a hat, and he chose the hat.
Hats indoors also provide a level of anonymity for those who do not want to be recognized in an airplane or robbing a bank.
My first "real" hat was a Homburg, which was required for one of my college jobs: pallbearer.
Karen Kingston's book Clear Your Clutter with Feng Shui really helped me to clean out the clutter in my house and my life. Before, I lacked the skill to clear out much of the unnecessary clutter that obstructs the flow of energy. Too much stuff physically and psychologically gets in your way. It can accumulate dirt and dust. Worse, it affects your life, health and business. Truthfully, you don't need a lot of stuff that gets stored or saved for the wrong reasons.
She gives specific techniques for getting rid of clutter. Clothes are worn according to the Pareto principle: you wear 20% of your clothes 80% of the time. Put the clothes you wear on the left side of the rack…throw away the 20% on the right that you never wear.
Your office is important. Can you move around easily? Are you comfortable? Move out old files, old papers.
Examine your clutter individually. Ask yourself how you feel about it, does it give you a good feeling or bring back bad associations. I talked to a friend about this, and she told me a story about how she has been holding 10 boxes for an ex husband for ten years. She threw them all out the next day. They only brought back bad memories.
How about those old wood golf clubs covered in dust? Throw them out; their time is gone.
I feel much better now, more energy. I'd been meaning to do this for years. It took a lot of time. It opens up energy. I'm glad I did it.
You could probably get rid of 20% of the systems that don't work anymore as well.
Inspired by Vic's grandfather's advice "people will never stop wearing hats", I wonder if perhaps shoes will lose favor with people. This seems to have occurred to me. I used to love shoes and bought many. Now since I work mostly from home, a pair of socks or sleepers are what I wear the most. Then since I mostly live in warm climates, sandals are what I wear the most for outdoors. The next is sport shoes for working out. Formal leather shoes, which I have a bundle of, are rarely worn. What is going to happen 50 years from now?
Victor Niederhoffer comments:
This will be very bad for China. There is not one manufacturer of shoes left in America. They're all in China an India now. When I worked in Wilkes Barre 50 years ago as tennis pro, there were at least 30 shoe manufactures in the Scranton Valley alone, all of whom where members of the club. Alas, Poor Yorick.
Leo Jia replies:
Yes, that would be very bad for China. But I tend to think that it would also not be easy for the world either.
Simply looking at the iPad shares in the world, we can see how big an exaggeration are China's GDP numbers from its real economic contributions/benefits. In the iPad case, China records the full $275 while its real contribution is only $10. I presume the shoes industry (and all others) would be similar only in varying degrees, with many American and European brands taking the big shares.
Look from the other way, China's economy is not as big as we think it is.

In Hawaii, everyone wears slippers and goes barefoot often. The feet get tough and the toes spread out in a more natural position which is wider. City feet get cramped in misshapen in the form of the latest fashion almost like Chinese foot binding. Native kids who have gone barefoot their whole lives have wide feet with space between their toes.
There is a new trend in running shoes towards a less structured shoe with a flexible sole that allows the foot to naturally flex during the running motion. Prior technology in running shoes put a large and rigid heel which forced a heel strike, which unintentionally caused greater impact on the knees. The flexible sole allows the foot arch to naturally flex and absorb the impact resulting in less impact to the knees and back. A popular shoe is the five toe design, similar to ancient Japanese toe socks. African runners run long distance barefoot.
It was Superbowl Sunday about 20 years ago and we were moored in my boat at my favorite remote bay. The night before there was no wind and absolutely no waves with the ocean flat as a bathtub. Its never like that. I thought to myself, "This is strange. So calm. Very unusual."
Sure enough around 2 am the palm trees start to sway. By dawn the wind was blowing 60 plus. My anchor let loose and the boat headed for the rocks. Just before hitting the rocks, the anchor caught. I was trying to move the boat but the motor wasn't strong enough to fight the wind so I had to pull the anchors one by one to pull the boat away from the rocks.
I remember distinctly my surfboard flapping in the wind horizontally on its cord totally out of control. I could not look into the wind as the rain and wind stung my eyes. The sea was foaming. That day 7 boats went up on the rocks or sunk. Later that afternoon the storm abated, sun came out, and I made it back to harbor.

There is a belief in the health and safety field is that "all accidents are preventable". The key is to properly access the range of risks and the "worst thing that can happen" and have the plan in place to mitigate those risks.
It appears that a good portion of local sailing instruction these days is devoted to teaching youngsters proper health and safety.
Strangely the least experienced and most experienced people, however, are often the ones that have the majority of accidents. The young have no experience and do not realize the risks, and the older ones have the experience and knowledge but have become complacent or willing to cut corners since "nothing like that has happened before".
Often there is technology and knowledge available to prevent accidents and deaths. So for those to suggest that a "true sport" need be associated with risk of death and imply "acceptable number of deaths" doesn't seem quite right for modern times— definitely heresy for those in the health and safety field. An idea best left for Hemingway stories.
One would think that once the full facts about the tragedy are learned that new safety procedures will be considered and improvements made.
I had the chance to hear Gary Jobson speak here in S Fla at a leukemia charity benefit about 10 years ago and he is a very impressive individual.
Safety tethers have been proven to have saved countless lives, and their use is absolutely the best accepted practice for sailing offshore, at night, or anytime that there is even the slightest chance of a crew member going overboard; PFDs, of course, should be worn at all times. These practices were exceeded by the WingNuts crew.
Is there any Health and Safety product made or which could be made to handle such extreme conditions? In cold water you have to fight hypothermia and drowning in rough seas.
Eyeballing June and July turns shows the turn off the bottom characterized by volatility and a range but the turn at the top is characterized by stagnation, a few doji's, then a sharp reversal. Is this a generalizable characteristic of big turns a la Magee or Nison? Second question. Will the top of the June range at bottom provide "support" at this level? What is "support" and how does it work? Is it psychological, or are the actual orders in place? Despite despised topic of the question its kind of hard to ignore. Certainly patterns can be quantified and tested but not without problems of generalization.
Paolo Pezzutti writes:
The top was printed as exhaustion of buyers. But the importance of the 1300 level should also be considered. It means that at present few people have the guts to buy new highs. However there are still many out there willing to buy dips, supports (such as round numbers), retracements, new moons and so forth. Don't know what would be needed to change this approach of investors and traders and start a new 'cycle' with different behaviors. What is needed to shake this confidence? Bad news about the US debt? Or the European crisis? No way. Already tried… Probably an unsatisfactory earnings report by Apple…. Paolo

We hopefully carry out the canes when the crowd is tossing down the tickets in disgust, we sniff for value when there is no value there–so says the financial press.
But what is our own attachment to this concept–catching a falling knife, holding a loser, getting involved in some fiasco stock since the market is beginning to bore, riding a coattail that turns into a skid, throwing in "just this once"? Why do we fail to follow our own good sense from time to time?
There must be a thrill or an ego impulse underneath this temptation to turn from the path and into the wind of long odds–"cause we can handle it".

I think that the chair has outlined many great themes in speculation, almost like laws:
1. Methods must be tested in order to find relationships of validation.
2. The laws of ever changing cycles are present in the market at critical-mass moments.
3. There is a high degree of relationship between markets and natural systems. What can be said of the "unknown"? What is this speculative doomer, the whispy apparition above the pond at days end? What law can be attributed to this unknown force that seemingly has uncanny timing?

I think it's simpler than that.

-We can amend that distribution of what can happen based on how we foresee the future diverging from the past
-That very distribution can now be used to determine how aggressive we might want to be withing a given risk (drawdown) constraint.
-If we don't exceed that drawdown constraint, and our distribution is reasonable of the future, the profits accrue.

I wrote this in a previous thread about the difference between speculators and gamblers, and I think it holds true: "Gamblers are willing losers who occasionally win; speculators are willing winners who occasionally lose."
At bottom, and at one time or another, most of us are gamblers. It takes a very disciplined, brilliant, and perhaps unrealistic person to only play games where the odds are in our favor. The reasons many engage in knowingly losing propositions are greater than the stars in the night sky in rural flyover territories. Entertainment and division rank high among them, sociability, peer pressure, guilt about the money they are risking (unconsciously disposing of it), fear of success, self-disgust, compulsive addiction to the stimulus-response loop, adrenalin junkie.
But all these are all proxies for the thing everyone is really seeking, usually unconsciously: a desire to be in union with the godhead, the creator, the divine purpose. As St. Augustine wrote in the opening lines of his autobiographical "Confessions": "You made us for thee, Lord, and our hearts will be restless until we rest in thee."
Phil McDonnell writes:
When I ask people why they do not invest in a guaranteed savings account or short term t-bills they usually respond that they are too boring. And they are, or at least used be because they could not lose. Most traders unconsciously seek to lose because it represents action and excitement. While I think the usual arguments that it takes assumption of risk to increase return have validity, at the sub-conscious level the desire is really no more complex than risk seeking for excitement.
Ralph Vince writes:
I agree — this is what frightens me about individuals who are out investing their own money — no kid needs to relive the station wagon as home for awhile as a consequence of Dad's gambling proclivities.
I'm beginning to think institutions are just the individual lambs in the wolves clothing of trading with other's money.And the reason I say this is because, again, not only can they not articulate their criteria for being involved in this, most criteria involve the ultimate metric of "what is the probability of getting smacked x% in the coming y period(s)."
And I don't see ANY of them operating that way. Rather, their risk metrics are ones that don't really tell them anything, analgesic salves that do not stave off the infection.
Russ Sears writes:
Personally, my record shows that I am more often guilty of trying to catch the falling knife on an individual stock and on an option trade, than I am on an allocation strateging or long term market timing basis. I believe this is because of two reasons, One reason is I am just to gullible for a single stock, and buy the story the more it goes down the more I am convinced it will pop, often averaging down. I believe most businesses as a whole are running honorable businesses, that is they are trying to do what is best for the long term. However, the exceptions happen and there are frauds/crooks and businesses that have agency problems (businesses run for the executives or employees short term interest) The second is that I am often guilty of believing that the studies timing is much more stable than it actually is. It may be that the market is over sold and will bounce back, this results is the crux of my "edge, but the time period is often part of the ever changing cycle.
I have helped this some by giving myself some boundaries or a do not buy or sell if held rules of:
1. If the market believes the board or leadership is not acting in the stockholders interest, based on key decisions they have made.
2. If there are union grievances making the press.
3. If there are rumors of fraud or accounting problems.On options buying time or gamma seems to work better. And in general I have learned to not do as many option trades as I am not as good at them as I think I am.
These rules are simply my adjustments for my own shortcomings.

The heuristic at work here is risk aversion where one would rather face a known small risk with bad odds of a big win, rather than a 51% favored odds with a risk of a large loss. It's very hard to overcome the natural tendencies.

Between the Folds, on Netflix, is a fascinating movie about origami and the new directions modern practitioners are taking the art form. Everything has folds, space, the galaxy,DNA, and market moves. The flat plane of a piece of paper, when folded takes on complex and dynamic forms, curves, moves and can mimic forms of nature and remarkably realistic forms. The new generation of origami including mathematicians and physicists use complex math and computers to design the folds to create realistic and beautiful forms.
I've always talked about the higher dimensions of the market above the flat charts, but reflecting on the transformation of a flat paper to complex design based on folds may reveal some interesting approaches and ideas to analyzing the folds, the turns of the market and what kind of forces and dynamics are being created. Paper, you see, is not a flat plane, but has dynamic properties and memory. The folds are memory, but the paper wants to return to flat and the tension creates a dynamic force with the intersection of the many vertices. What is the force created when the market reverses? What is the effect of the intersection of two or more folds or turns in the market. How does the turn in the market represent a memory and what force is trying to return to the old form.
We've recently seen a turn off the bottom in this market and there seems to be a memory in the turns from the down turn. How might this "unfold"?
In trading, we can all agree that fewer conditions or filters results in better conclusions, better understanding, and less curve fitting. Conditions or filters block information. Too filters can result in less new insight and fewer opportunities.
Here is where trading is a good lesson for life. As we grow older our tendency is to filter out information, people, paths. It's partly a necessity to avoid the bad or overload, but good things can be missed. Our experience tends to specialize our knowledge and narrow our focus. Though this has some benefit in expertise what opportunities or knowledge or growth may be missed. Ignoring, filtering or refusing to hear or listen to ideas we disagree with or that are different than our own may lead to narrow mindedness, missed opportunity to change and important information. For younger people it might be seen as closing doors. Meeting new people, hearing new ideas, going to new places. Nobel laureates advise not to tighten parameters too tightly as the surprise result may reveal itself. I recommend opening up parameters, let the fresh air in. Let's not become grumpy old men. We've seen closed small minded people and don't look on them with respect. Broad vision is necessary to see above and beyond the noise. You really need to force yourself against the tendency to close the mind.
Most people love to think and act alike. It starts in infancy when you mimic your parents or siblings. Teens are notorious for talking, dressing, acting, and thinking alike, and many dangers arise for them as a result. Young adults I notice tend to dress alike and sport similar hairdos. In Japan, consensus is a compulsion.
In trading it has been common recently to see everyone piling on in the same direction during the day. The internals confirm this. Big players seem to like to wait to see which direction the day is going and all pile in the same direction. Are we much more than fish? Apparently not. There doesn't seem to be much science, analysis or thinking going on in the market recently, nor in the news coverage. It looks like group think. The problem is it's hard going against, in life and in markets. However when used as strategy it's productive, but when used for misdirected frustrations, its not.
I was reading about the famous double slit experiment and then thinking about the Heisenberg uncertainty principle, the math, and the observer effect. I wonder what types(if any) of market implications could be attributed to the observer effect.
Ken Drees writes:
Interesting. I was contemplating this more than a few weeks ago too, but let it drop. It made me think of Schrodinger's Cat:
Schrödinger's cat is a thought experiment, usually described as a paradox, that Austrian physicist Erwin Schrödinger devised in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. The thought experiment presents a cat that might be alive or dead, depending on an earlier random event. In the course of developing this experiment, he coined the term Verschränkung (entanglement).
I was considering how a trade is alive and real only when one puts it on or opens the box and everything else is meaningless– the counting, the theory, the expected outcome– all meaningless unless you commit and then make it real and apart of consciousness, reality, an entity.
Michael Cohn adds:
Schrodinger's kitten's also interesting as a thought experiment across space and time. What I recently learned about the uncertainty principle was that there is a different way to think about it. I always thought about it in terms of how the observer may be creating the uncertainty in measuring both mass and acceleration with the instruments. What I now understand is because of quantum uncertainty these particles actually don't really know exactly where they precisely are at a given point in time beyond a prob distribution so if they don't know where they are I certainly can't help them as much as I would likes to be able to do so…
Jim Sogi comments:
2 closing related issues:
There's the insidious cursor and key watcher viruses.
Another related aspect is the inadvisable practice of putting your cursor over the execute button onscreen and having it execute without having touched the mouse, or accidentally touching the mouse or keyboard at the wrong time triggering the trade. Been there, done that.
There is also the issue of order field depth, which is a form of "disclosed" watching, and other order related manipulation issues perhaps posing, perhaps honest bid, perhaps flow bashing or bandwidth hogging, flashing. Lack surely can speak to many of these techniques he sees in individual stocks.
Russ Sears adds:
If risk is defined as what is not known in the future that if it happens would hurt you, than imagination of what could happen causes you to avoid and prevent that perception.
Done to extremes this creates new risks from the over abundance of care and lack of focus on any other risks even to the point of altering the minds ability to cope. Think interest rate duration management and the creation of the tranches in the securitization process and modeling of those securities. Done in mass this creates bubbles, hysteria, or pop-stars. ( I believe this is the "Lady Gaga" "Apple" link. It is not mysticism but the creation of popular mystic.)
Much of psychology is the study of how unrealistic risk perception creates a difficult life and alters their reality for the fearful and anxious. Why should the markets be immune?
Ken Drees comments:
Lady Gaga is to Apple as Amy Winehouse is to Rimm.
For SPY from 2000 on here is the count of "inside" and Outside days, if inside day is defined as High < prior day High and Low > prior day low. Likewise outside day is High > prior day high and Low is < prior day low.
It would appear that the inside days do not like to occur in middle of week. While outside days like to occur in the middle. But Mondays do not have many occurances of outside days.
Jim Sogi comments:
Steve Nison in Candlesticks describes the "Abandoned Baby" pattern where price gaps up, then gaps down the next day.
This occurred two days ago. The pattern was bearish (despite prior drop) according to traditional candlestick theory and modern scientific analysis.
It has been just over 100 points pretty much straight down since the high over a month ago to today's low. Common sense and hope tells you it ought to be bullish, but it ain't necessarily so scientifically speaking. The drops sure are dizzying and the pops are breathtaking as well. You can see see how they design them to scare the living daylights out of you or suck you in deeper and the rallies are designed to give you hope but just shy of a new high. Takes some strength, stamina and savvy to be involved here. In 08 the drops went into the hundreds. The action is all day and all night long without let up.

The Winners of the least effort contest were jointly in a tie. Mr. Gary Rogan and Mr. Steve Ellison. I will split the prize between them. The creative and physical ideas of Mr. Rogan were very excellent and best of all, but there was no testing. Mr. Ellison gave a great test, and a complete answer, but Rogan can't be denied his place either. vic
I'll give a prize of 1000 to the person or locus of his choice that comes up with the best way to test the principle of least action or a related principle of least effort.
It's in honor of my grandfather. Whenever I'd ask him which way he thought the market would go he'd say, "I think the path of least resistance is down" starting with Dow 200 in 1950. We need some more quantification around here.
You might consider max to min or a path through a second market back to home. Or round to round? Or amount of volume above or blow. Or angle of ascent versus angle of descent. Or time to a past goal versus the future? Or some mirror image or least absolute deviation stuff?

With utmost humility and clearly no cultivated sense of any derision for the Fourth Estate, I would submit that since it is the public that is always flogged and moves last, the opinions of all media writers, tv anchors are the catalysts, the penultimate leg of the opinion curve. A test of the opinions of the fourth estate on the markets would provide the most ineffective wall of support or so called resistances. Fading the statistically calculated opinion meter (if one can devise one such a 'la an IBES earnings estimate a media estimate of market opinion) and go against it consistently over a number of trades, one is bound to come out a winner. Can I test it? Yes its a testable proposition, subject to accumulation of data.
Alston Mabry writes:
The following graph (attached and linked) is not an answer but an exploration of the "least effort" idea. It shows, for SPY daily since August last year, the graph of two quantities:
1. The point change for the SPY over the previous ten trading days.
2. The rolling 10-day sum of the High-Low-previous-Close spread, i.e., "max(previous Close, High) minus min(previous Close, Low)". This spread is a convenient measure of volatility.
Notice how these quantities move in tight ranges for extended periods. These tight ranges are some measure of "least effort", i.e., the market getting from point A to point B in an efficient fashion. As one would expect, the series gyrate when the market takes a temporary downturn. Also note how when one of the quantities swings above or below it's mean or "axis", it seems to need to swing back the other way to rebalance the system.
Bill Rafter writes:
This nicely illustrates how relative high volatility is bearish on future price action.
Jim Sogi writes:
The path of least resistance would be the night session. Low liquidity allows market mover to move market. Every one is asleep. Dr. S did a study some years ago. Updating shows total day sessions yielding 94 pt, but night session yielding 232 points. Don't sleep…stay up all night or move to Singapore. Recent action is in line with hypothesis.
Bill Rafter writes:
Haugen's "The Beast on Wall Street" (i.e. volatility) came to the conclusion that if you want less volatility in the markets, keep them closed more, to essentially force the liquidity into specified periods. That is, 24 hour markets promote volatility. Or a corollary was that a market is never volatile when it is closed. [this is from memory and I may also be regurgitating from a personal conversation with him]. An oft cited example is the period in the summer of 1968 when equities were closed on Wednesdays to enable the back offices to get up to date with their paperwork and deliveries. During that time the Tuesday close to Thursday opening was less volatile than expected (twice the daily overnight vol).
One could take this thought and stretch it to say that the periods of least resistance would be those without heavy participation. One could easily compare the normalized range (High/Low) of those periods versus the same of the well-participated periods.
Craig Mee writes:
You would have to think that in 68 there was sufficient control of price and news dissemination. In these times of high speed everything, that this could create bottlenecks and add to the volatility. No doubt a bit of time to cool the heels i.e limit down and up for the day restrictions, is a reasonable action, even if it goes against "fair open and transparent markets" but unfortunate it seems little is these days.
Bill Rafter replies:
I should have been more specific about the research: take the current normalized range for those periods of high liquidity (when the NY markets are open) and compare that to the normalized range of the premarket and postmarket periods. Do it for disjoint periods (but all in recent history) so you don't have any autocorrelation. My belief is that you will find there is less volatility intra-period during the high liquidity times. While you are at that you can also check to see during which period you get greater mean-reversion versus new direction.
If that research were to show that (for example) you had greater intra-period volatility during the premarket and postmarket times, and that those times also evidenced greater mean-reversion, you could then conclude that those were the times of least resistance. That would answer Vic's question. Okay, now what? Well you could then support an argument that with high volatility and mean reversion you should run (or mimic running) a specialist book during those times. That's not something I myself am interested in doing as it would require additional staff, but those of you with that capacity should consider it, if you are not yet doing so.
Historical sidebar: '68 was a bubble period caused in part by strange margin rules that enabled those in the industry to carry large positions for no money. The activity created paper problems as the back offices were still making/requiring physical delivery of stock certificates. The exchanges closed trading on Wednesday to enable the back offices to have another workday to clear the backlog. The "shenanigan index" was high during that time.
Phil McDonnell writes:
Bill, you said "During that time the Tuesday close to Thursday opening was less volatile than expected (twice the daily overnight vol)."
For a two day period and standard deviation s then the two day standard deviation should be sqrt(2)s or 1.4 s. So the figure of twice the volatility would seem higher than expected.
Or am I missing something?
Steve Ellison submits this study:
The traditional definition of resistance is a price level at which it is expected there will be a relatively large amount of stock for sale. Starting from this point, my idea was that liquidity providers create resistance to price movements. If a stock price moved up a dollar on volume of 10,000 shares, it would suggest more resistance than if the price moved up a dollar on volume of 5,000 shares. To test this idea, I used 5-minute bars of one of my favorite stocks, CHSI. To better separate up movement from down movement, for each bar I calculated the 75th and 25th percentiles of 5-minute net changes during the past week. If the current bar was in the 75th percentile or above, I added the price change and volume to the up category. If the current bar was in the 25th percentile or below, I added the price change and volume to the down category. Looking back 200 bars, I divided the total up volume by the total up price change to calculate resistance to upward movement. I divided total down volume by the total down price change to calculate resistance to downward movement. I divided the upward resistance by the downward resistance to identify the path of least resistance. If the quotient was greater than 1, the past of least resistance was presumed to be downward; if the quotient was less than 1, the path of least resistance was upward.
Previous 200 bars Up Date Time Up Points Volume Down Points Volume Resistance 3/25/2011 15:50 53 6.49 99431 61 -7.38 149867 15311 Down Resistance Actual Resistance Ratio net change 20310 0.754 -0.03
Unfortunately, the correlation of the resistance ratio to the actual
price change of the next bar was consistent with randomness.
In the summer reading vein, I very much enjoyed Alex Berenson's first novel, The Faithful Spy, with his main character, John Wells. The next two books in the series, The Ghost War and The Silent Man, were very good, too. The next book, The Midnight House was just okay, and Berenson's most recent effort, The Secret Soldier, is unfortunately a failure.

My son turned me on to the spy series by Vince Floyd, including Transfer of Power, The Third Option, Extreme Measures. The books are surprising well written current historical fiction with three dimensional characters with full backstories and touching personal details. The bad guys are complex but the series has a decidedly non PC attitude, so that's fair warning. Its good entertainment though and hard to put the books down. Great for airplane or vacation reading. The main character is an assassin but has realistic doubts and feelings. I briefly compared it to Clancy, but it is astonishing how the technology just a decade back seem so archaic and outdated. I have them downloaded to Kindle for iPad.

And given our particular interest in markets here, one might enjoy the David Liss's "Benjamin Weaver" series. Set in early 18th Century London, Weaver is a former pugilist and highwayman come "thief-taker", i.e., private detective. The son of a Jewish Portuguese stock jobber, his cases involve intrigue and deception revolving around the relatively newly formed stock exchanges, combinations, Bank of England and corporate giants of the time.
Liss' has also written "The Coffee Trader", set 50 years before in Amsterdam, the locus of which is cornering the market in the newly discovered "coffee fruit" and "The Whiskey Rebels", set in America just after the revolution focusing on the attempts of those whiskey rebels on the western frontier attempting to bring down Alexander Hamilton and the Bank of the U.S.
Liss began by writing his first Weaver novel, "A Conspiracy of Paper" while a doctoral candidate at Columbia. All are well written and offer looks at finance and markets, many pretty familiar, not to mention murder, a large cast of ne'er-do-wells, prostitutes and a pretty frank look at the cultural and social biases of the time. He even has a Watson-like sidekick for Weaver, Elias Gordon, a likable bounder of a Scottish surgeon given to bleeding and such, who also schools Weaver in scientic method and probability. A lot going on, fun and good stuff.

William Gibson plays with the theme of pattern recognition in his technologically edgy, subversive books. One of the books, in fact,is called "Pattern Recognition." I have devoured all of them as soon as they come out. The newest one, "Zero History," contains the throwaway insight that when/if someone succeeds in aggregating order flow, the market will cease to exist. Hubertus Bigend — not a hero or a bad guy, but rather a nexus — is one of the most fascinating and ambivalent characters in fiction — comfortable with unpredictability, glinting Bertelsmann, Ralph Lauren and Goldman Sachs.
My family had a great adventure on an ski mountaineering expedition to the Ruth Glacier in Denali National Park Alaska last week. We stayed at the Mountain House. We were skiing several objectives in the area and had good weather. We could see Mt. McKinley close by. The primary danger was falling into a crevasse in the glaciers. The glaciers are 3 mile acres, 30 miles long, and 4,000 feet deep. I read a number of books on crevasse rescue, bought gear, practiced and headed into the wild. It's quite amazing how much one can learn from books. We flew in a ski plan from Talkeetna 50 miles into the wilderness and were dropped off with our supplies of food and wood for 5 days. We had to melt snow for water.— keep looking »
