The options market is pricing an expected move of ±14.66% (±$33.00) for ALNY (Alnylam Pharmaceuticals, Inc.) earnings on Thursday, October 29, 2026 (before open). That is the mid price of the $230.00 at-the-money straddle expiring Friday, November 20, 2026, with ALNY at $225.10 as of Oct 21, 2026 3:59 PM ET (CBOE delayed data). The nearest expiration is 22 days after the report, so this straddle also prices non-earnings movement and likely overstates the pure earnings move.
