Just to be clear, I don't believe that there is a large short position outstanding nor do I believe the Company is suffering from naked shorting. The manipulators are careful to close out their short positions and to not maintain too large a short position at any one time. Of course it is hard to tell what the largest size of their short position is since the short interest is only reported bi-monthly.
I have seen on several occasions where there is large aggressive buying due to some good news culminating in a large buy at or near the highest ASK of the day. I think these are times when the manipulators got "caught with their pants down" and panicked into covering immediately.
