Just like going long at $280, going short now is a mistake. Sure this thing may drop another $5 or $10 but with all the bad news out there, you gotta assume anyone who wanted to sell or short would've done it today. At least in the short term. And the short-term shorties will cover as soon as they see a hint of strength in the stock. The squeeze could easily push up $10 in a day. Be careful.
