At this point there are going to be little to no shares available to buy. To short someone has to buy the shares that are going to be shorted so they can be sold short. That can drive the price up even more. Also when you try to short only to learn that you just bought the stock up another 10 but you actually shorted when it was down that same 10, it will scare the hell out of you and you will want to cover immediately; thereby raising the price again by covering so soon.
I am serious, when the float is low to non-existent like it is on this stock, you can try to short it at 85 only to learn that your broker had to buy the shares at 90 so you could short them. Now you have shorted at 85 but the buying you caused has just added fule to the upside and you are already down 5 before you get started.
That is a hard way to make money. Not to mention the sleepless nights and health risks.
