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 ±5.2% (range 80.50–89.25) by Sep 18, 2026. ATM straddle: 4.38 @ strike 85 · ATM IV: 30.7%.
