RE "Why would someone short a $.68 stock"
The price of the stock doesn't matter, you have to look at percentage return. Would you rather short a $100 stock to $50, or a 68 cent stock to 34 cents? It doesn't matter of course, it's the trend and the likelyhood of the decline that does. Also, PPHM has a track record of huge dilutions at market discounts. So I'd pose you the opposite question: until or unless that record changes, why wouldn't you want to short that 68 cent stock? Shorts have always made money on PPHM. Why would you think now is any different?
Because R&R may write a report at some point?
Because in the next year or so, there might be phase 2 results? Beause eventually Duke may say something?
Now do some analysis on the odds of those potentials vs. the rock solid PIPE history. The attraction to being bearish on PPHM is really not much of a stretch.
