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 ±4.4% (range 60.25–65.85) by Sep 18, 2026. ATM straddle: 2.80 @ strike 63 · ATM IV: 26.6%.
Probability distribution
