Not even a proper haircut for the market that had grown a bit wild a woolly – just a little off the top.
In a reversal of the recent pattern, we got a pre-opening sell-off originating overseas and then buying right from the U.S. open. Probably best viewed as a little test of excessive bullishness and possible buyer's exhaustion courtesy of some European virus/shutdown news, not yet a thorough re-evaluation of the bullish thesis.
