I found it hard to believe the market would reach back to lows of the days with all the strength in the tech stocks a few hours ago, but just before 3 PM markets seemed poised to retest lows and I thought my assumption would be wrong.  Then out of the blue the market went vertical (9ish S&P points) in a span of 5 minutes.  Urgent buyer?  Or maybe this one?
