Alta has to be just about done dumping. They had so many shares and the volume indicates a slow selling process. They no longer come up as a 5% holder in Corcept. My guess is that they're just about done. It looks like Longitude Capital Partners is really boosting its position. Sutter Hill also owns a huge block. This company is so tightly held that it's going to rocket on great news which will come IMO. I'm just accumulating weekly at this point. It's pretty clear that someone is grabbing the shares as Alta dumps. They have been liquidating for a long time and must be done at this point...if not, then I'm guessing that they're under a million shares.
