Lot of “key days” yesterday or just more head fakes?

A key day reversal is defined by Stockcharts.com as “a one day chart pattern where prices sharply reverse during a trend. In an uptrend, prices open in new highs and then close below the previous day's closing price. In a downtrend, prices open lower and then close higher. The wider the price range on the key reversal day and the heavier the volume, the greater the odds that a reversal is taking place.”
