This drop strikes me as simply the reaction of folks who climbed on board expecting a big run after the conference news, etc.... When it appeared to lose steam (volume+price), they bailed. I dont see a 'pump' here... just normal market dynamics. Heck, I was tempted at 4.70.... anticipating a buy back much lower soon. My experiences of getting burned by this daytrader mentality stopped me. This is a long term hold for me now...period.
