Options-implied move vs. analyst target

The chain's longest listed expiration (Jan 15, 2027, 99 days out) implies 29.42% annualized vol near the money — a one-standard-deviation move to roughly $229.03–$311.91 by then.

Options-implied (~68% band), 99d
$229.03now $270.47$311.91
Analyst target range, ~12mo
$339.00avg $393.50$436.00

Two different things on the same scale: the purple band is the options market's own near-term volatility pricing (statistical, 99 days out); the blue band is sell-side opinion on a roughly 12-month horizon. Neither is a forecast.
