Research Brief

Priced range47.16–51.46
Call concentration50.00
Put concentration46.00
Max pain reference47.50
- 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 47.16 to 51.46. Max pain at 47.50 sits inside that range, 3.7% below spot.
Spot
Max pain
47.1649.31 ± 2.1551.46
Confirmation level
A close beyond 51.46 or below 47.16 at the 14 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.

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.

Aggregate chain data supports concentration, participation and pricing analysis. It does not identify trade aggressor, opening versus closing activity, multi-leg intent or dealer inventory.
Options Intent Radar
Likely noise
There is useful activity, but aggregate chain data does not isolate participant intent.
The options read is mixed, so divergence is not strong enough to classify.
Likely noise matters because it connects the options headline to the actual evidence: $4.6M of estimated gross traded notional, calls · 91+ days · atm, and a no clean flow/price divergence backdrop. Use it as a research priority signal, then validate the chart, liquidity, event calendar, and risk before acting.
