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 HSIC gamma exposure
The HSIC options chain represents Henry Schein and its exposure to product demand, regulatory decisions, clinical developments, and reimbursement trends. Its GICS classification is Health Care Distributors. Use the chart to identify where modeled exposure is concentrated and whether that concentration is consistent across expiration choices.
The HSIC 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.

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