May I point out to you that any event that hasn't yet happened is only a guess. Some guesses have a high probability, others low, but everything is a guess. The facts at this moment are that AMGN has traded $54.94 pre-market at 7:42AM.. that's a fact.
As for anyone using YOUR advice, that's a LOW probability even though you have a higher regard for yourself than others apparently do. But that's just a guess also!
