CP,,,,,,,,,,,,,,,,,,,the considerable existing short position could be a hedge against a long position such as the warrants or some other instrument we may not be aware of,,,,,,,,possibly,,,,,I was wondering if this short position on RVX was as high before warrants came into being??...I agree,,,,why else would you short a play that could explode in your face,,,,,,,,,,,,,,,,,,,,,,I know biotechs are famous for their wild swings in share price but really why still be short with pending positive news that could cripple a short over night!!,,jmo
