The way this usually works is someone buys a really large short position at a good price and then publicizes true information that convinces at least some long traders to sell their positions. There's also some question to me how much liquidity there is here. Their volume isn't tiny (at least according to Yahoo Finance) but I don't actually know how many shares are trading hands. There might not be a deep enough book to make it worth making the trades.
