Doubtful. But even if it made it back to $7.00 tonight, or even back to $6.50, tomorrow premarket will bring another round of sellers who have not yet heard the news, and tomorrow at the opening of the regular trading hours, massive selling will hit the stock because major holders of ECYT won't liquidate during after hours or premarket. If you bought after hours and are up, you might want to take your profits and go to bed thankful. Chances are your profits will have disappeared by market open tomorrow if you don't take them now.

Yes, unfortunately you can't tell what is going to happen tomorrow morning because the big holders will have to decide what they are going to do. I expect huge swings tomorrow though. It might be possible to swing trade this during the day and come away with several dollars of gain.
