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 ±3.8% (range 30.70–33.12) by Sep 18, 2026. ATM straddle: 1.21 @ strike 32 · ATM IV: 23.1%.
