It is interesting to note that Friday the 6th of July, the SP closed at 1351.80. And Friday the 13th July SP closed at 1351.70 . Similar proximities occurred on 2/10/2012 and 2/03/2012 at 1327.30. Headlines in the media such as Bloomberg state: "US stocks gain for week, erasing losses".

I am drawn to look at such things as rank correlations and inversions in such books as Kendall on rank correlations to study this with a view to reducing the ability of the market mistress to relieve one of funds.

Chris Tucker asks: 

Is the options market in ES, SP, SPY and component stocks large enough to pin the S&P?

Alas, it should be treated solely as market trivia, of no predictive value. I wouldn't worry about newswire's interpretation; I'd be more worried about optimized coding interpretations. How should researcher classify daily or weekly delta? E.g, is change of mere .10-.90 on SP500 trading 1350.00 = no change, or should some percentage threshold classify as a change rather than unchanged? Percent change makes more sense for longer-term (years) of studies. The levels near 666 should normalize different delta than levels near 1576. I guess that levels of interest rates might also have impact — but we've been relieved of this variable issue for a couple of years hind and hence by the true Libor fixers.

Victor Niederhoffer comments: 

One is often involved in things too trivial or microscopic. Indeed that is what was said to me 50 years ago when I started counting eighths in individual stocks in my undergraduate thesis–a count that set off a field that one is told has not been entirely fruitless. Thanks for the firm guidance.

Anatoly Veltman replies: 

It's interesting that 25 years ago I was taught that the less observed the security is — the better the technicals! In that regard, one-eighth 50 years ago might have been more predictive than .90 delta in e-mini today. We're in the age of battle of the black boxes, the most successful of whom manage to relieve us of funds the moment we start over-relying on a particular minor indicator.
