You will have another chance. This will pop after hours today and catch retail investors caught up in the euphoria of the good news from the panel, then it will open down 10% tomorrow. GSK will work with GS to destroy the value of THRX over the next twelve months, then they will offer to purchase the company.
Best, try shorting STSI, I've made a small fortune on that one. Also, consider shorting NUGT, I've done really good with that as well-- and shorting NUGT will continue to be a good trade for another six weeks. Consider going long THRX, its going higher. Best of luck.
