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 ±12.7% (range 185.91–239.96) by Nov 20, 2026. ATM straddle: 27.02 @ strike 212.5 · ATM IV: 53.7%.
