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 ±21.6% (range 21.86–33.87) by Nov 20, 2026. ATM straddle: 6.00 @ strike 30 · ATM IV: 81.1%.
