Closed at exactly $4.45, but ticked higher to $4.48 a second after the close. There was an acceleration up from trend early mid afternoon, setting up the shorts attack to try to keep the close below $4.43, but the effort failed...
I'm guessing tomorrow might be a little bit more exciting than today, with good potential for a higher open, and if short covering begins tomorrow morning, it could move in earnest.
Last report I had the float is 44 million and there are 4 million shares short, reportedly with a $4.43 trigger. Today perhaps did did look like some short covering... but we've seen nothing like the volume that would have allowed them to exit, yet.
my hunch is that I don't think the upside surprises are done, yet...
