Options-implied move vs. analyst target
The chain's longest listed expiration (Nov 6, 2026, 29 days out) implies 63.33% annualized vol near the money — a one-standard-deviation move to roughly $53.67–$76.99 by then.

$53.67now $65.33$76.99
Analyst target range, ~12mo

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.
