If there was a problem with the data, I would think there would have been a press release. Even if they were in a quiet period. Plus all the other trials would have been halted. Surely some people will panic and sell, so this may be a great opportunity to stock up on cheap shares.
Remember yesterday's pre market drop. This is an orchestrated attempt to take the price down by a paid hack at the least credible source out there - The Street. When does the SEC turn their focus on these guys?
