Is the party finished? Judging from the way AMGN is behaving lately, it looks as if there's an underlying problem that has not yet been made public. The huge pop in the overall market on 9/13 had little effect on AMGN, and the stock is getting hammered today in another strong market. Obviously, something is going on. If anyone has some information.... please!
Support when the market is down and sideways action when the market is up. I wouldn't call that a concern. AMGN is in a secular bull market and eventually will see triple digits. There was a recent profit taking (no problem), just some consolidation for another leg up. Have been watching these events for the last 30 years with individual stocks.
