As for me, I'm not surprised, because I don't trust that all the trading is on the up & up. My belief is, other MM's are playing Patty Cake with these shares, to make it look like they are trading normally. I call BS on that. :)
Many were buying into the false hope that the stock was going to run higher this week so they absorbed the shares as they were diluted. But the trading didn't have the strength late in the day that it had earlier. Wouldn't be surprised to see it down again tomorrow.
