Bungler, I opened a chart of PPHM daily bars and look over the past 24 months (that is 8 quaraters) and I could not find a pattern in the large volume days with a PPS lift.
It is however correct that the PPS did often move up some till the Q/CC then retraced some. However, nothing like we saw yesterday (high volume and about 25% price increase).
I do NOT want to draw any conclusions of what that means, just saying that something NOT usual is happening to the stock price of PPHM. That doesn't have to mean anything. However ALL other high volume bars were most of the time associated to NEWS but came into existence when the news was DISCLOSED.
As far as I know there was no real PR-grade news yesterday, yet we had the big move.
