A couple of weeks ago, one of those Fools, All-Star zzlangerhans, nicely summed up the bear case for our community:

The near-term hopes of Alnylam (and RNA interference in general) to be taken seriously as part of the future [armamentarium] against infectious disease were dealt a severe blow ... when the company reported failure of ALN-RSV01 to significantly reduce the incidence of bronchiolitis in RSV-infected patients in a phase IIb trial. ... I believe this development will drain market cap from the company as institutional investors edge quietly towards the exits. If this was an early proof-of-concept trial, the "near-miss" angle might hold water but it doesn't really make the grade for a phase IIb study. ...

I've profited before from volatility in Alnylam, but that was at a lower price entry point with more cash in the coffers. This time round, I'm seeing a lot more tunnel before any light appears.
