This stock is knocking at multi year highs and it looks like the shorts are trapped. Almost 6 million shares short with an average volume of 380k means it would take the short sellers 15.65 days of buying to cover! Earnings are due on Thursday, maybe the company will provide a catalyst in their comments that triggers a breakout and a good old fear driven bout of panic buying by the shorts?
Here is the description of what the company does from Google Finance.
