Based on the 2 form 4's on 12/2 and 12/9 (dates approximate) I'm guessing there is a MM with plenty to unload. They haven't been able to sell many at 7 since the 4's so I'd bet they'll hope to fill as many 7's as they can over the next week or more until their supply is gone. I'm guessing we stay in the 6-8 range until their diluting shares are gone.
