Option Greeks Aggregation

Option Greeks Aggregation refers to the process of summing up the individual risk sensitivities of a portfolio of options positions. These sensitivities, known as Greeks, measure how an option price changes in response to shifts in underlying factors like price, time, and volatility.

By aggregating these values, traders can understand their total exposure to specific market risks across their entire book. This is crucial for managing complex derivative portfolios where multiple positions may offset or amplify each other.

It allows risk managers to see a net position for Delta, Gamma, Theta, Vega, and Rho. Without this aggregation, it would be impossible to accurately hedge a large portfolio against systemic market movements.

It transforms individual, disjointed risks into a cohesive, manageable risk profile. The process relies on linear summation, as most Greeks are additive in nature.

This provides a clear view of how the total portfolio value will react to various market scenarios. It is a fundamental practice in both traditional finance and decentralized crypto options protocols.
