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 ±5.7% (range 10.26–11.51) by Oct 30, 2026. ATM straddle: 0.625 @ strike 11 · ATM IV: 36.1%.
Probability distribution
