I have addressed the feasible reasons for delay enough times that I find it hard to restate, but I will summarize by saying that science is slow, there is considerable manipulation/corruption that requires strategy that may not be obvious and Missling does not have the psychology of an American. I really think you will be happy you did not sell in the long run. If you needed the money returned quickly, biotech was not a good choice. Otherwise, I believe it will pay off.
