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 ±21.2% (range 1.09–1.68) by Nov 20, 2026. ATM straddle: 0.295 @ strike 1.5 · ATM IV: 79.6%.
