## Portfolio Gamma Aggregation

Portfolio Gamma Aggregation is the process of calculating the net sensitivity of a trading book to changes in the underlying asset price across all held options positions. In derivatives trading, Gamma measures the rate of change in an option Delta relative to the underlying asset price movement.

When a portfolio contains multiple options with different strikes and expirations, the individual Gammas must be aggregated to understand the total exposure to price acceleration. This metric is critical for market makers and hedge funds to manage the risk of large, sudden price swings.

By aggregating Gamma, a trader can determine how much their overall Delta position will shift as the market moves. It is a fundamental component of dynamic hedging, as it dictates the required adjustments to maintain a neutral or target risk profile.

In the context of cryptocurrency, where volatility is high, accurate aggregation prevents massive unintended directional exposure. Proper management ensures that as the underlying price moves, the portfolio does not become dangerously over-leveraged.

Ultimately, this practice allows firms to maintain stability despite rapid market fluctuations.
