yes, my personal strategy is buy stocks that have tanked 40-50% in a day to profit from the rebound. With UVSE, it did in fact rebound after its July 28th collapse, but it reaffirmed a bottom at 0.010 throughout last week and so that is why I set a limit order to buy over the weekend at 0.0105 and luckily it got filled. Trading is an on-going learning experience and even the best look back with hindsight and say shoulda-woulda-coulda. The key is to recognize the patterns and just make the bet because there's no such thing as knowing what will happen in the next few seconds, minutes, hours or days.
