Research Brief
IEX has a bullish chain read with 38/100 evidence alignment.
The practical question is whether the underlying confirms the options concentration. The chain prices a reference range of 233.84–244.04; The largest call open-interest concentration is 230.00; the largest put concentration is 210.00. The most active strike by current volume is 230.00.

Put concentration210.00
Max pain reference220.00
- Price holds or improves while call-side concentration remains elevated.
- Price weakens while call pressure fades or reverses toward puts.
- Options and the weekly trend are not yet giving the same message.
Priced Move
Where the chain says movement becomes exceptional
Options imply 233.84 to 244.04. Max pain at 220.00 lies outside the priced range, so it is a weak near-term anchor.
Spot
Max pain
233.84238.94 ± 5.10244.04
Confirmation level
A close beyond 244.04 or below 233.84 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.

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
Multi-expiry position-maintenance candidate
Activity is spread across expirations with heavier open interest than current volume, which can be consistent with position maintenance.
Options pressure and weekly price action are pointing in the same constructive direction.
Multi-expiry position-maintenance candidate matters because it connects the options headline to the actual evidence: $9,820 of estimated gross traded notional, calls · 91+ days · otm, and a bullish flow confirms price backdrop. Use it as a research priority signal, then validate the chart, liquidity, event calendar, and risk before acting.

Aggregate chain data does not identify trade aggressor or opening versus closing activity; call/put concentration is not proof of market direction.
Roll detection is conservative because opening and closing legs are not directly observable in this snapshot.
