Picked up an interesting tidbit from a commenter at ZH that goes by the name Crashisoptomistic. The S&P closed 2011 virtually unchange from the years open, within less than 10 cents in fact. 2011 close $1,257.60, off 0.003181% from the years open. Ok, that could be a coincidence, but then the poster mentions that the close on June 30th, the end of the first half, was up PRECISELY 5%. As in precise to three decimal places, 5.000%.
That is ODD.....
