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 ±6.7% (range 1,055.30–1,207.70) by Nov 20, 2026. ATM straddle: 76.20 @ strike 1,130 · ATM IV: 27.1%.
