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 WMT gamma exposure
Walmart is the closest thing the equity market has to a consumer-spending readout, and its options market treats it accordingly: flow is institutional, implied volatility is low for a company of its size, and gamma exposure stays persistently positive thanks to heavy overwriting by income and index-adjacent holders. Dealer hedging in WMT reliably dampens moves, which is why the stock's daily ranges are so much narrower than its market capitalization would suggest.
Gamma builds around a specific and well-telegraphed calendar: quarterly earnings, monthly retail sales data, and the holiday season. The call wall behaves as a real ceiling during retail rallies, and because the post-split strike ladder is dense, WMT is one of the more reliable monthly OPEX pin candidates in consumer staples. The gamma flip level is rarely tested, so a cross is genuinely informative - it has generally coincided with the market revising its view of consumer health rather than of Walmart specifically.

WMT GEX FAQ
What is WMT GEX (gamma exposure)?
WMT GEX measures the aggregate gamma that options market makers carry across all WMT strikes and expirations. When WMT GEX is positive, dealer hedging dampens price moves (selling rallies, buying dips); when it is negative, hedging amplifies moves. It is calculated from open interest and each contract's gamma across the Walmart Inc. options chain.
What is the WMT call wall and put wall?
The WMT call wall is the strike with the largest positive gamma exposure and often acts as resistance, while the WMT put wall is the strike with the largest negative gamma exposure and often acts as support. As of the latest snapshot, the call wall is at $120, the put wall is at $105, the gamma flip level is near $119.00.
What is the WMT gamma flip level?
The WMT gamma flip (zero-gamma) level is the price where net dealer gamma crosses from positive to negative. Above it, market-maker hedging tends to suppress WMT volatility; below it, the same hedging amplifies moves in both directions. The latest computed flip level is near $119.00.
