Not necessary. They have 3.7 billion shares of stock in their Treasury Account which they have accumulated over the years though stock buybacks. At $87 per share currently they have a war chest of $322 billion. I think that just might be enough to by any company with the exception of Apple.
The stock price has just about completed a round trip after the fast track news before the bell yesterday. The extensive number of shares traded cannot be accounted for by retail traders. It is simply too high. Therefore that just leaves the large hedge funds moving the stock price. In my view one or several deep pocked entities bought like crazy when the news broke yesterday morning and then shorted starting at the market open. They made money in each direction. None of this has anything to do with the fundamentals of THLD and has everything to do with trading for profit using other peoples money.
The company has a very bright future which will be proven out as the two Phase 3 trials conclude. Hang in there if you can stomach the wild gyrations. For my part that's what I am doing.
