Today, stocks were hammered, with the S&P 500 breaking to fresh lows into the bell to finish more than 2.5% in the red.

Treasurys were bid across the board to leave yields sharply lower. The dollar trended higher throughout the day to reverse overnight weakness.  The VIX jumped by more than 30%, and settled above 24, its highest close since the immediate aftermath of the short-vol-blowup on Feb. 13.
