Free MRNA GEX - Live Moderna Gamma Exposure
Free MRNA GEX shows where modeled gamma exposure is concentrated in Moderna options. Change expirations to compare the call wall, put wall, gamma flip, and strike profile around clinical results, regulatory decisions, product demand, and research spending.

Gamma Exposure represents the sensitivity of an option's delta to changes in the underlying price. Market makers hedge their gamma exposure, creating support/resistance at high GEX strikes.
Key Levels:
- Call Wall: Strike with highest positive GEX (resistance)
- Put Wall: Strike with the largest put GEX, shown as the deepest negative bar (support)
- Gamma Flip: Where total GEX changes from negative to positive
Positive GEX: Market makers sell into rallies, buy into dips (stabilizing).
Negative GEX: Market makers buy into rallies, sell into dips (amplifying moves).

Understanding MRNA gamma exposure
The MRNA options chain represents Moderna and its exposure to clinical results, regulatory decisions, product demand, and research spending. Its GICS classification is Biotechnology. Use the chart to identify where modeled exposure is concentrated and whether that concentration is consistent across expiration choices.
The MRNA call wall, put wall, and gamma flip depend on the contracts included in the calculation. Recompute the chart after changing expirations and compare the distribution around the current price. The output is positioning context rather than a forecast.

MRNA GEX methodology and limitations
QuantWheel calculates MRNA GEX from the selected expirations, available options data and the formula displayed in the calculator. The result summarizes modeled gamma exposure by strike.
GEX is a model output, not observed dealer inventory or a price forecast. Open interest does not identify who owns an option, and the displayed call wall, put wall and gamma flip can change when the inputs or selected expirations change.
MRNA GEX FAQ
What is MRNA GEX?
MRNA GEX estimates gamma exposure across listed MRNA options using option gamma and open interest. It helps you compare how modeled exposure is distributed by strike and expiration. MRNA GEX does not reveal actual dealer positions or predict where MRNA will trade.
How do I read the MRNA call wall and put wall?
QuantWheel labels the MRNA call wall as the strike with the largest positive modeled GEX and the MRNA put wall as the strike with the largest negative modeled GEX in your selected data. Compare both with the MRNA price and expiration choices. They are reference levels, not guaranteed support or resistance.
What is the MRNA gamma flip?
The MRNA gamma flip is the price where modeled net gamma crosses zero for the selected MRNA options data. Compare it with the current price and the shape of the strike chart. The MRNA gamma flip is a model output, not a trading signal.
Which expirations should I use for MRNA GEX?
Start with the nearest MRNA expiration to study short-dated positioning, then add later expirations to compare a broader part of the options chain. Each selection changes which MRNA contracts are included, so compare one expiration with a combined view before drawing conclusions.
Is the MRNA GEX calculator free?
Yes. You can run up to three free MRNA GEX calculations per day on the public tool. After using those calculations, continue for free in the GEX demo. Check the current QuantWheel pricing page for plan access details.
