The market looked poised to start the week off on a positive note, but early morning sellers took over after the opening bell. The $SPY briefly dipped under $198 and traded under $200 for most of the session before a late day surge sent the $SPY to $202. I don't think a chart accurately conveys the volatility we saw in the market today, with prices falling dramatically before rallying sharply.
