Obviously don't just short something because I said it was what I consider a decent idea yesterday. Wait for the right signals before entering a short position on any equity or with any instrument. Whatever that might mean for you. My idea is merely to profit off the stock's return to equilibrium. Obviously don't short it as the price is still increasing. But as of now at 8:24 AM EDT (GMT -4) the price is settling a bit before the open down towards 230.00. Good luck.
