It's hard to tell, but I think this is the pullback from resistance, and also fueled by jitters before Friday's financials and press conference. Obviously we're not expecting stellar financials, this isn't what this is about, but I wouldn't be surprised that other announcements will make this bounce after Friday. I expect to break 16$ on the next try within a few weeks.
Because we can never be sure with these volatile bio plays, it might be a good idea to take up a 3:1 or 4:1 call/put position.
