Yes, but he got burnt shorting CTIX in 2013 when he last tried to do a hatchet job. I would guess that he's short again and is facing a margin call. He's probably noted the conference and update on 12th Jan and is starting to panic. Shorting a micro cap stock is a foolish activity - as we all know they can move with far more volatility and wipe out your short position. It's not as though there options on CTIX which means he's had to borrow stock to short and is facing a massive loss. He may also face an email from the SEC if they see what he's up to!
