it could be someone trying to flush out the last of the JPM stock - or it could be a stack to get the punters to jump the 20c orders and take out the sell side.
You wouldn't try and buy the stock like that - you know its going to chase the price up - you would buy of the wall. If the wasnt JPM overhang in the market you would say it was a prop !
ASX asleep at the wheel again .
