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 ±3.3% (range 327.49–349.99) by Sep 18, 2026. ATM straddle: 11.25 @ strike 340 · ATM IV: 19.0%.
