I'm not worried... when a stock goes down so much, it becomes more volatile. Big investors leave because of the uncertainty, shorts try to take advatange of the uncertainty, and stock price drops until it finds until it finally finds a bottom and base. This doesn't just happen. It takes some time. You have the big investors leaving first in line, replaced by new investors, before the new investors kick up the price and you see a rebound. This all takes a couple of weeks up to a couple of months.
