Research Brief
IMOS has a volatility chain read with 54/100 evidence alignment.
The practical question is whether the underlying confirms the options concentration. The chain prices a reference range of 44.74–60.34; The largest call open-interest concentration is 70.00; the largest put concentration is 45.00. The most active strike by current volume is 60.00.
Priced range44.74–60.34
Call concentration70.00
Put concentration45.00
Max pain reference55.00
- A clear directional pressure reading develops and price begins to agree.
- Volatility falls and the chain remains directionally mixed.
- Options and the weekly trend are not yet giving the same message.
- 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 44.74 to 60.34. Max pain at 55.00 sits inside that range, 4.7% above spot.
Spot
Max pain
44.7452.54 ± 7.8060.34
Confirmation level
A close beyond 60.34 or below 44.74 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
Front-loaded volatility
Near-term options are materially richer than later expirations, consistent with concentrated event or immediate-risk pricing.

- 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.

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
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: $56,222 of estimated gross traded notional, calls · 91+ 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.
