Options-implied move vs. analyst target

The chain's longest listed expiration (Apr 16, 2027, 190 days out) implies 65.58% annualized vol near the money — a one-standard-deviation move to roughly $12.28–$34.34 by then.

Options-implied (~68% band), 190d
$12.28now $23.31$34.34
Analyst target range, ~12mo
$7.40avg $13.19$18.97

Two different things on the same scale: the purple band is the options market's own near-term volatility pricing (statistical, 190 days out); the blue band is sell-side opinion on a roughly 12-month horizon. Neither is a forecast.
