I'm not going to mention them but there are more than a few bio-techs that are up anywhere from 50% to 500% in the past couple of weeks. This smacks of a huge bubble/over reaction/squeeze, and I fear the day when it all ends and they do all end...i.e. the internet bubble, the real estate bubble, the nifty fifty bubble, the energy stock bubble of the 1980's,etc. There are many more examples but I think I've made my point.
I don't know when this bio sector bubble/squeeze ends and if EXEL will continue to accelerate, but I do know one thing, I don't want to own it when the music stops. Meanwhile enjoy the fruits and have a nice weekend.
