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 ±8.3% (range 57.91–68.41) by Nov 20, 2026. ATM straddle: 5.25 @ strike 63 · ATM IV: 35.3%.
