Expected move — Sep 18, 2026 (15 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 ±6.5% (range 88.44–100.64) by Sep 18, 2026. ATM straddle: 6.10 @ strike 95 · ATM IV: 38.4%.
Probability distribution
