Seems like the shorts waited until the 50 and 100DMA's were right on top of each other to send a clear signal that this TA event is going to resolve to the downside, not the upside.... and conveniently this is occurring right before OpEx.
"Companies with less growth such as Alexion and Regeneron trade at a multiple far times greater. Thus suggesting that fear of the unknown could be the reason for the misaligned valuation."
Yes indeed, it must be fear that caused all the increased accumulation since the double-bottom on Sep 23rd Oct 11th in the $53s. If that's as low as the Shorts can go their build-up will help us to double, tho.
