The volatile movement of this stock is becoming very unsettling. I am a long, have been since 2000. I've spent the entire weekend reading all of the posts on this board (thanks to everyone for their DD), but I am still concerned with the drop in pps. This started happening before there were any rumors of scientists leaving, and now I am afraid that the only reason the price jumped up on Friday is because many people who were waiting to get in on this stock thought it was a good entry point.
