I am pretty sure that FD has sold a whole bunch of his shares, if not all. Not the ones he holds through the concertible bond but the shares he was outright long in addition to that. He loaded up in the market previous to releasing the PR about lending SIAF the $25 million. However, I don't think that he has any left...
You guys need to remember that selling shares you own is NOT shorting. You are shorting if you sell shares you don't own/ have.
