What is Gamma Exposure (GEX)?
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 MCK gamma exposure
McKesson operates in health care distributors, so its options may reflect earnings alongside changes in product demand, regulatory decisions, clinical developments, and reimbursement trends. Review the full MCK strike profile, including both positive and negative modeled exposure, before interpreting the displayed walls.
The MCK 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.

MCK GEX methodology and limitations
QuantWheel calculates MCK 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.
MCK GEX FAQ
What is MCK GEX?
MCK GEX estimates gamma exposure across listed MCK options using option gamma and open interest. It helps you compare how modeled exposure is distributed by strike and expiration. MCK GEX does not reveal actual dealer positions or predict where MCK will trade.
How do I read the MCK call wall and put wall?
QuantWheel labels the MCK call wall as the strike with the largest positive modeled GEX and the MCK put wall as the strike with the largest negative modeled GEX in your selected data. Compare both with the MCK price and expiration choices. They are reference levels, not guaranteed support or resistance.
What is the MCK gamma flip?
The MCK gamma flip is the price where modeled net gamma crosses zero for the selected MCK options data. Compare it with the current price and the shape of the strike chart. The MCK gamma flip is a model output, not a trading signal.
Which expirations should I use for MCK GEX?
Start with the nearest MCK expiration to study short-dated positioning, then add later expirations to compare a broader part of the options chain. Each selection changes which MCK contracts are included, so compare one expiration with a combined view before drawing conclusions.
Is the MCK GEX calculator free?
Yes. You can run up to three free MCK 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.
