The CEO lost a ton of credibility when he surprised the market with the 5.50 secondary and then he promised pipeline details in late Summer and that didn't happen. He seems like a smart guy but he does not know how to deal with shareholders or analysts or "the street."
About the only reason I own it now is because I think Novartis buys the whole company for several times the current share price. Hope it happens soon but my guess is mid-2018.
