Quote from topdown:
Baby bio's - not for me I almost bought some ADLR today solely based on the chart that seemed to be basing. Glad I didn't - down 57% AH on bad news. Call me a pussy, but I'll stick with the PBE instead of individual bio plays, damn.
PBE and IBB along with BBH are the only way to play biotech without seeing your investment drop 75% overnight.
