there is a reason that biorunup owns a bunch of this stock.
yes, a lot of people wait until 6 or 3 months before the final readout to get in. But that's why, quite predictably, if you get in before THAT, you will make money even if all you do is sell into the 'late-comer' runup.
the traders can go ahead and run along for a year if they think they have a good chance of making %50-%100 on their trades in that time frame. Because that will be the additional cost of getting in a year from now. (Obviously, much greater if it is halted for efficacy.)
