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 ±0.9% (range 78.35–79.82) by Sep 18, 2026. ATM straddle: 0.735 @ strike 79 · ATM IV: 5.3%.
Probability distribution
Model & assumptions →The curve shows where a lognormal model, fed with current implied volatility, puts the range of outcomes at this expiration. Shaded: the expected-move band.
