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 ±8.5% (range 315.22–373.92) by Nov 20, 2026. ATM straddle: 29.35 @ strike 345 · ATM IV: 36.1%.
