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 ±4.3% (range 32.00–34.86) by Oct 30, 2026. ATM straddle: 1.43 @ strike 33.5 · ATM IV: 30.6%.
