The chart shows how Mr. Market set up the haymaker: a double top followed by a swoon that left bears scrambling for cover on Tuesday.  Stocks opened that day on a nasty gap that would not merely have fooled bulls, but panicked shorts as well.  A weak rally followed, then a sharp pullback into day’s end.  You’d think bears might have sat back and enjoyed it, but no. The next day, they allowed themselves to get sucker-punched with yet another short-squeeze on the opening bar. By day three, bulls and bears had both figured out where things were heade and pulled their bids.  Expect the downtrend to exhaust itself on very low volume today, setting up a new short-squeeze that could start the process all over again.
