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 TSM gamma exposure
TSM is the foundry that everything in the AI trade ultimately depends on, and its US-listed ADR options carry a gamma profile shaped by one structural quirk: the underlying shares trade in Taipei overnight, and TSMC reports monthly revenue figures outside US hours. The result is a stock that gaps regularly on information the US options market cannot react to in real time, so dealer re-hedging concentrates into the opening minutes of each session.
That gap-driven rhythm makes the TSM gamma flip level a better read on overnight risk than on intraday direction. Open interest is more institutional than in the US chip designers - fewer weekly lottery tickets, more monthly hedging of AI supply-chain exposure - which gives its call wall and put wall unusual durability. Because TSM manufactures for NVDA, AMD and AAPL alike, its GEX is also the least company-specific gamma signal in semis and the closest thing to a read on the sector's aggregate order book.

TSM GEX FAQ
What is TSM GEX (gamma exposure)?
TSM GEX measures the aggregate gamma that options market makers carry across all TSM strikes and expirations. When TSM 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 Taiwan Semiconductor Manufacturing Company options chain.
What is the TSM call wall and put wall?
The TSM call wall is the strike with the largest positive gamma exposure and often acts as resistance, while the TSM 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 $410, the put wall is at $420, the gamma flip level is near $414.68.
What is the TSM gamma flip level?
The TSM 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 TSM volatility; below it, the same hedging amplifies moves in both directions. The latest computed flip level is near $414.68.
