The HFs that are short BBRY are much like the retail that is short - sheeple. The smart ones borrowed years ago and covered months ago. The rest showed up late to the party, and drunk at that, they didn't notice the respectable folk leaving. So they kept drinking the koolaid, trashed the place and soon the cops will show.
These are not big houses, and more than a few will implode when the #$%$ hits the fan and they have to cover. As it is, they have simply been shorting all they can, piling on, doubling and tripling down, in the hope that downward pressure caused by this and their paid minions out in our lousy excuse for a "business press" will keep the price low until something catastrophic happens. It should have happened by now, many times over, so they just don't get it. They will.
