Biotech investors should be wary of the inevitable rotation of the industry. The iShares Biotech Index (IBB) is down 3.5% today on slightly higher volume. Money flow as been decidedly negative over the last three weeks.
The current price of $250 is testing support at its 10-week EMA. If it rebounds on robust volume then all is well.
Biotech's bull run began in early 2012.
