Call concentration280.00

Max pain reference260.00
- A clear directional pressure reading develops and price begins to agree.
- The current chain read already agrees with the stored weekly trend context.
- Volatility falls and the chain remains directionally mixed.
Priced Move
Where the chain says movement becomes exceptional
Options imply 215.33 to 296.91. Max pain at 260.00 sits inside that range, 1.5% above spot.
Spot
Max pain
215.33256.12 ± 40.79296.91
Confirmation level
A close beyond 296.91 or below 215.33 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.

Positive call-side proxy Negative put-side proxyHighlighted row is nearest spot strike
Scenario proxy = gamma × open interest × 100 shares × spot² × 1%. Calls are positive and puts negative by convention. Missing Greeks use a Black-Scholes estimate from stored IV with zero rate and dividend assumptions. Open interest does not reveal who is long or short, so this is not observed dealer positioning or a forecast.
Volatility Curve
Back-loaded volatility
Longer-dated options carry more implied volatility than the front expiry, so risk is priced farther out.

- Matched expiry closereported only after maturity
Eligible snapshots must have a dated market session, stored signal, and point-in-time market reference. Each observation uses one read per market session and the first stored weekly close on or immediately after expiry; its original calculation version is retained. It is an evidence audit, not an executable strategy or evidence of future performance.

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: $22.6M of estimated gross traded notional, puts · 8-21 days · itm, 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.
