Expected move — Oct 16, 2026 (44 days)
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 ±12.3% (range 9.47–12.13) by Oct 16, 2026. ATM straddle: 1.33 @ strike 11 · ATM IV: 43.8%.
Probability distribution
