Wednesday started off well enough for the S&P 500 as prices popped more than 1% at the open. And a wave of follow-on dip-buying pushed the index even higher through the morning. By lunchtime, it looked like this was just another example of alternating up and down days.

But the afternoon session had other plans and hit the rebound with a sledgehammer, knocking it down more than 3% from the intraday highs, turning this into the largest bearish intraday reversal we’ve seen in a while.
