Options-implied move vs. analyst target

The chain's longest listed expiration (Oct 16, 2026, 8 days out) implies 44.38% annualized vol near the money — a one-standard-deviation move to roughly $160.87–$183.49 by then.

$160.87now $172.18$183.49
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, 8 days out); the blue band is sell-side opinion on a roughly 12-month horizon. Neither is a forecast.
