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 ±3.9% (range 176.59–191.05) by Sep 18, 2026. ATM straddle: 7.23 @ strike 184 · ATM IV: 23.4%.
Probability distribution
