I'm trying to figure out why the DJ Biotech index has been clobbered. 26 of the 27 components are down and many are down big. Yeah, I know about GILD. But 26 out of 27 stocks?? One failed drug from one company would not tank the entire sector like this - the index is down almost 4%. Many others down too - LIFE, etc. Was there some legislation? Was there options-related manipulation short-covering into yesterday? Any genuine insight appreciated.
