Uh...not to burst your bubble, but the price action this year implies exactly the opposite of what you are saying.
Shorts have already made their money here. The stock is down 80% from it's recent highs. They have laughed all the way to the bank, and are now on the sideline with absolutely zero anxiety.
Do you know how shorting a stock works? They don't have to stay in until zero. Their desired margin is already realized tenfold.
