A Contest, from Victor Niederhoffer

In honor of our new spec and Larry, I hypothesize that like Pascal's Law, that a small move in a big market will cause probabilistically, a large move in a smaller market. I'll give 1,000 bucks to the personage that comes up with the best predictive relation on that theme.
Mr. Isomorphisms replies:
I would start looking in smaller markets that are dependent on the larger one. Eg, look at a town where >50% of the workers are employed at one company. The decline of various parts of Detroit's supply chain could fit this story. Or Iceland/Scotland with their large banking sectors relative to within-country wealth.

Let us first get an idea of which markets are big and small. Glancing at the futures contract listings in the newspaper, here are some rough estimates of open interest:
3-month Eurodollar 10,000,000
S&P 500 e-mini 3,100,000
10-year US Treasury 3,000,000
Crude oil 1,300,000
Soybeans 670,000
Euro 465,000
Gold 400,000
Wheat 360,000
Cocoa 175,000
Copper 155,000
Silver 150,000
Palladium 31,000
Oats 8,500
Lumber 5,000
Next, I would like to introduce the bullwhip effect. Most goods have a "supply chain" that begins with raw materials, progresses to components and finished goods, and may include warehouses and stores. The bullwhip effect posits that, the farther "back" in the supply chain an operation is (farther away from the end customer), the greater the swings in production and inventory will be in response to fluctuations in end customer demand. Here is an article on the subject.
During the dot-com crash in October 2000, stocks briefly rallied on a glowing earnings report by JDS Uniphase. The CNBC screamer correctly noted that JDSU was a component supplier, farther back in the supply chain, and its record sales had probably just bloated the inventories of companies such as Cisco Systems that had already reduced forward guidance.
From this perspective, lumber seems a good candidate for a Pascal's Law study. It is a raw material that must go through additional processing before reaching most customers, and its futures market is very small. The S&P 500 is a large market that theoretically is based on the whole economy and should be more sensitive to final sales.
Using 3 months as a rough rule of thumb for total lead time in a typical supply chain, I compared quarterly net changes in the S&P 500 with net changes one quarter later in the lumber price.

09/30/14 338.0 -2.3 09/30/14 1965.50 21.00
There were only 11 data points since 2012, not enough for significance. In a regression, the t score was -1.55, and the R squared was 0.21.
The quarterly changes in lumber were a little larger in percentage terms (about 8% mean absolute change) than in the S&P 500 (about 6% mean absolute change).

Excellent. You win the prize. Everything a report should be. (A little weak on the predictivity but not your fault.) If it was easy, we would all be wealthy men.
