Priced Move
Where the chain says movement becomes exceptional
Options imply 341.76 to 467.96. Max pain at 400.00 sits inside that range, 1.2% below spot.
Spot
Max pain
341.76404.86 ± 63.10467.96
Confirmation level
A close beyond 467.96 or below 341.76 at the 21 Aug expiry would exceed the move currently priced by this chain.
Important limitation
The range is a pricing reference, not a forecast; volatility can reprice sharply after news or as expiry approaches.

Options Intent Radar
Volatility expansion bet
The strongest message is movement risk: expected move and implied volatility are carrying more signal than direction.
Options are pricing movement more than direction; compare expected move with the stock's actual weekly change.
Volatility expansion bet matters because it connects the options headline to the actual evidence: $5.0M of estimated gross traded notional, puts · 91+ days · otm, and a volatility flow versus price backdrop. Use it as a research priority signal, then validate the chart, liquidity, event calendar, and risk before acting.
