I've been watching for a short squeeze. The setup is there but depends on how the market receives earnings/CC on Feb 9th. A rise in PPS will put pressure on the shorts. The SI as reported by NASDAQ:
Settlement Date Short Interest Avg Daily Share Volume Days To Cover
12/31/2010 11,681,702 885,212 13.196502
Doesn't cut-n-paste well but the numbers are there.
Could be interesting, and I'll initiate a position on signs of a breakout.
