IBB is down big today. Maybe the Celgene flop? But

Bigger biotechs are often the first to get whacked when market direction is going to change.
(Smaller biotechs are news-driven, as IPIX will be soon.)
Also, they were pumping IBB like crazy on CNBC, which I listen to when I'm driving (radio, not watching TV while driving). That's often a sign that something is about to crater, when Wall Street wants individuals to buy it.
