I would think the bears will be taking a big gamble here if they take an initial short position Monday. Further downside from here will be limited to companys present cash per share, $7 - 8 depending on which article you read. That means shorts - best case - would get a $2 - 3 payday from here.
Longs, on the other hand, have a chance for a much bigger payday. If autopsy on test death patient turns out to be 100% non drug related, then this thing probably goes to $25+ very quickly, as regular testing will continue and its nearing the end of the test trials (or whatever they are in medical terms.)
I expect a jump Monday morning, but a further $2 buck drop wouldn't bother me all that much. I'd triple my investment at $8.50. Very little downside from there unless the whole thing goes belly up, which I doubt.
