✦ Today’s options flow
- Call and put volume are fairly close today — no strong directional lean in the options flow.
Options-implied move vs. analyst target
The chain's longest listed expiration (Nov 6, 2026, 29 days out) implies 90.10% annualized vol near the money — a one-standard-deviation move to roughly $54.29–$91.25 by then.
Two different things on the same scale: the purple band is the options market's own near-term volatility pricing (statistical, 29 days out); the blue band is sell-side opinion on a roughly 12-month horizon. Neither is a forecast.
