still only one Biotech of the 30+ I follow below the 50 dma. Many are above by 25% or more. The last time this happened the entire group retraced until about 1/2 fell below the line. I still think that this area can be traded with reasonable success if you're willing to be patient and accept the risk. Watching DCTH, AVAN, CRIS, TGEN, STEM, for trades, DNDN potential short, holding AELA, PRCS, ALTH, and CTIC at this time.
