I think the MM's are still holding it down. I don't think they will let it run until they absolutely have to. They must not feel the squeeze yet. I think as we get closer to the 15th, they will start moving it up, IMO. And after the 15th we will have the anticipation to hear the results of the meeting, so it will keep the price in limbo, probably in the 4's and 5's.
I'm sure many people have bought and sold, but probably more have added to their positions. A few weeks ago this board had about 1/4 of the float, probably more now. Many probably didn't even add their positions! :)
