✦ 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 (Oct 16, 2026, 8 days out) implies 56.41% annualized vol near the money — a one-standard-deviation move to roughly $154.27–$182.39 by then.
Two different things on the same scale: the purple band is the options market's own near-term volatility pricing (statistical, 8 days out); the blue band is sell-side opinion on a roughly 12-month horizon. Neither is a forecast.
