Biotech: I can't always discern between a long raising legitimate concerns and a flipper who is disingenuously trying to discourage the board so he can profit off them. However, I think I'm right about 80 to 90% of the time. I'll keep my eye on you and get a better sense over time if you are genuine.

I don't trade AMBS, I'm all in, so I don't profit by raising my concerns. Why do I raise them? Because I think getting at the truth is always a good thing, especially if you are in a speculative stock. I make my decisions based on what I believe to be the truth about a stock. The closer the mb is to reality, the better for all, IMHO.
