Would somebody please enlighten me? What can possibly be going on in the minds (I use that term loosely) of the short sellers? Each reporting period over the last several months, the short interest has been going up substantially (which, of course, explains why the stock price goes nowhere) and yet during that period, there has been nothing but a string of very positive news for the Company, including the FDA approval of a platform drug. I can understand betting on a "one trick pony" company that has not yet received approval--but here is a company that not only has received approval, but it is approval of a platform drug, meaning that there are many more combinations that should receive approval in the future. Furthermore, several of their drugs are being marketed. It just defies any reasonable explanation. That's why if anyone can enlighten me, I would appreciate it very much. Could it have something to do with that analyst that has a $5 price target on the Company? Thanks.
