I would counsel patience. And rather than hoping for a buyout at 100, I would hope that they reject any overtures until ibrutinib has wider approvals. The point of investing in these companies is not to make a few points, but to find the next GILD or CELG.
PS When you say "all in", does that mean that you have put all of your money into this one stock? If so, I can understand why you're frustrated and probably worried. I'd advise you to sell half of it immediately and worry 50% less.
