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 ±6.1% (range 323.08–365.38) by Nov 20, 2026. ATM straddle: 21.15 @ strike 340 · ATM IV: 24.5%.
