The options market is pricing an expected move of ±15.44% (±$33.05) for MKSI (MKS Inc.) earnings on Wednesday, November 4, 2026 (after close). That is the mid price of the $210.00 at-the-money straddle expiring Friday, November 20, 2026, with MKSI at $214.00 as of Oct 21, 2026 3:59 PM ET (CBOE delayed data). The nearest expiration is 16 days after the report, so this straddle also prices non-earnings movement and likely overstates the pure earnings move.
