Options-implied move vs. analyst target

The chain's longest listed expiration (Nov 6, 2026, 29 days out) implies 50.11% annualized vol near the money — a one-standard-deviation move to roughly $183.39–$243.71 by then.

$183.39now $213.55$243.71
Analyst target range, ~12mo
$170.00avg $216.59$298.00

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.
