Expected move — Sep 18, 2026 (16 days)
Methodology →Read from option prices: the at-the-money straddle costs this much, so the market is pricing a move of about that size in either direction by this date. It is an estimate of movement, not a prediction of direction.
Options are pricing a move of about ±9.0% (range 250.75–300.25) by Sep 18, 2026. ATM straddle: 24.75 @ strike 275 · ATM IV: 53.9%.
Probability distribution
