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 (Jan 15, 2027, 99 days out) implies 38.84% annualized vol near the money — a one-standard-deviation move to roughly $740.66–$1,116.22 by then.

$740.66now $928.44$1,116.22

Analyst target range, ~12mo

$932.00avg $1,180.78$1,415.00

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.
