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 ±6.2% (range 78.17–88.42) by Sep 18, 2026. ATM straddle: 5.12 @ strike 83 · ATM IV: 37.9%.
Probability distribution
