I bet its a guy trying to trigger a squeeze, We had huge volume shorting the stock , this volume is ok, but no where it needs to be to demonstrate a squeeze is on. We need to break yesterday's volume ( as a starter ) and to touch 10.86. It could happen today but needs to touch 10.86 OR need to see inreasing volumes. I think it is one one short player who just coveredabout 150 k shares.
Gives u an idea how fast it could hit 12 if some one had to cover 3 million shares. They wont trigger a squeeze all at once, usually they dont want to make it that obvious. More money to be made in a series of moves before the big one!
