Options Gamma Exposure

Options gamma exposure refers to the aggregate sensitivity of a portfolio or market to the rate of change in delta relative to the underlying asset price. Gamma measures how much the delta of an option changes as the underlying asset moves.

When market makers have high positive gamma exposure, they are forced to trade in the direction of the market to remain delta-neutral, which can exacerbate trends. Conversely, negative gamma exposure forces them to trade against the trend, which can act as a stabilizer or lead to rapid volatility if they are forced to cover positions.

In the crypto options market, understanding the distribution of gamma exposure across different strike prices is critical for predicting localized volatility. Large gamma positions often act as magnets or barriers for price action.

By calculating the total gamma of the market, analysts can identify levels where price movement might accelerate or stall. This concept is central to understanding how options positioning influences the liquidity and stability of the underlying spot market.
