The S&P 500 is already up 8.6% YTD, but volume is anemic. The combined 18.9B of S&P 500 component shares traded is a 20% drop from the same period last year and less than half the 48.5B shares traded during the same period in 2008. Today's action was no different: 3.32B shares in NYSE composite volume, the third lowest volume day of the year.
