RE:Is PMN worth the Investment?YES imho, and a year ago I would have said no.
It is wise, because the market has not yet digested the valuation just awarded a minor competitor with a 2nd-hand drug, and while the market is also rightly skeptical of PMN management, those concerns have been alleviated somewhat with the CEO's departure. PMN is still valued as if bankruptcy is a near term risk, but that is no longer true.
In short the risk/reward has changed significantly for the better over the last 6 months (like 10X better not 2X) while the market has remained in an emotional funk because the market is not rational, it's a player not an investor.
