The reason the stock was moving down was the anticipation of a 3 month delay in the PDUFA date. The news is now out so the there is no more reason to sell in anticipation of a new PDUFA date. The selling was rediculous anyway. In the great scheme of things what is a 3 month delay.
I think you're right. Uncertainty about an exact PDUFA date has built in an artificial low. Now that facts, not speculation, are out, the price should recover to high achieved in early July. Anybody trying to play this as a day trade is just looking to lose money. A September $7 call for $.75-$.85 would be nice for a one month double (or triple?) your money bet.
