ha ha serves them right,
basically short selling is basically a forcast way of buying, you take x amout of shares promising to give them back y amout of time later you sell them hoping the price will fall so you buy them back at a lower price to replace the share you took so making money.
so people have come to buy these shares but there are not many avaliable so people can name their price so its costing people more now to replace the shares than they got for them.
This is one of the things that killed the banking industry I think
red to red black to black blue to bits
