Research Brief
ACA has a mixed chain read with 29/100 evidence alignment.
The practical question is whether the underlying confirms the options concentration. The chain prices a reference range of 140.03–149.97; The largest call open-interest concentration is 150.00; the largest put concentration is 145.00. The most active strike by current volume is 140.00.

Call concentration150.00
Put concentration145.00
Max pain reference145.00
- 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.
- Front-expiry volatility is rich, so the signal may be event-driven and vulnerable to volatility compression.
Priced Move
Where the chain says movement becomes exceptional
Options imply 140.03 to 149.97. Max pain at 145.00 sits inside that range, 0.0% from spot.
Spot
Max pain
140.03145.00 ± 4.97149.97
Confirmation level
A close beyond 149.97 or below 140.03 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.

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
Multi-expiry position-maintenance candidate
Activity is spread across expirations with heavier open interest than current volume, which can be consistent with position maintenance.
The options read is mixed, so divergence is not strong enough to classify.
Multi-expiry position-maintenance candidate matters because it connects the options headline to the actual evidence: $538 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.
