One more comment: in my humble opinion, a short squeeze, if it happens, will be much more severe than these 50 cent ticks. We're talking about buying a third of the company here, not just the "marginal share".
Most of the shorts' only prayer of covering below where they sold is total collapse of the business. (Several of them have actively *boasted* of their dependence on that scenario right here on the board.) How else can 1/3 of all shares outstanding be purchased without the market noticing? Aaaaaand ... well, anything is possible but some things are not very likely.
