Good observation by all. When the price falls on low volumn (w/o news), I don't worry much. I think you are spot on about a bit of manipulation. With few buyers and sellers, the MM needs to move shares from time to time, to keep the pump primed------so to speak. For those who are getting a bit "antsy" I'd like to remind you that Dr Langer is one of the best in BioTech. He simply would not lend his name to a procedure or company without having complete confidence. He WILL get us FDA approval for human trials. That is all we should ask of him. After that, it's in the hands of the FDA and "luck of the draw".
