The 10Mil + short shares are probably not held by people who shorted before the gap down. I would have covered, just too big of a gain dropped right in your lap. All the smart shorts have traded out and all the dumb ones are in. The ones who shorted after the gap.
If you are short, you should cover. Put you money in the market long on tech stocks and blue chips. They are rallying while you are pissing around here trying to skim an extra dollar.
