i would bet that a good bit of this is short cover

i would bet that a good bit of this is short covering. We all know that we should hear something back from the FDA in the next 1-2 weeks. I can't imagine anyone sitting on a short position wants to be short this stock prior to that news hitting. that said, i'm not savvy enough to figure out short position, changes in shorts, etc. - someone on here who follows that stuff can probably figure that easily out by looking at the trend over the past few days.
