Greeks Exposure quantifies the sensitivity of a cryptocurrency options portfolio’s value to various underlying market parameters, including changes in the underlying asset’s price, volatility, time to expiration, and interest rates. It represents a fundamental set of measures for assessing and managing risk in options trading.
Mechanism
The calculation of Greeks exposure relies on options pricing models, typically Black-Scholes or its adaptations for crypto, which utilize current market data, specific option parameters, and implied volatility. Each Greek (Delta, Gamma, Vega, Theta, Rho) measures a specific risk dimension. These values are continuously updated in real-time as market variables fluctuate, providing an immediate risk profile.
Methodology
Managing Greeks exposure involves actively monitoring these sensitivities against predefined risk limits and implementing hedging strategies. Traders or automated systems buy or sell underlying assets for delta hedging, or other options for gamma and vega hedging, to adjust the portfolio’s overall risk profile. This continuous management aims to maintain a desired risk neutrality or directional bias, optimizing for potential profit while systematically minimizing loss.
