Key in djsp - short interest at 5/28/10 was 1,672,505. That does not include all the shorting from last week and this week. It has to be over 2 million shares by now. At 5/28 the short interest had climbed 1,000% in 3 months. At normal volume of 200K share or so that's at least 10 days to cover. It will NOT be easy to get out since even a 5,000 share order is hard to fill once the buys start coming in.
Not guranteeing it is going to happen but a serious short squeeze is not hard to see with this sort of picture. A lot of people shorting under 6 will be very fortunate to see any profit and in all likelihood will take losses on those bets.
