Definitely the shorts, but damn the panic selling that follows. The only plus I see from today is call volume which tells me some kind of news is coming, it could very well be the coverage from MS.
Tell you one thing, I'm getting tired of the fickle investors who give shorts a free lunch and even more tired of the shorts arrogance.
If longs want to stop a short attack all they have to do is put the shares they own for sale at say 25 dollars. By doing that they are no longer available to shorters. Never leave your shares uncalled for if your company is the target of a short attack. You could get lucky and they might be forced to buy yours.
