Computer trading. You have to seperate the hedge funds and their computer trading, from investor trading. The big investors are all holding their positions, there is no evidence of big time or insider selling. TSX volume is normal if not lower. Witness the high fees the shorts are paying to borrow their BBRY shares, not to mention the possibility of naked shorts with nothing to hold onto. The computer traders are running, or soon will be running, around like squirrels in a cage, trying to find a way out, of their terrible predicament imho.
