Besides Delta, What Are the Other ‘Greeks’ a Market Maker Must Manage?

Market makers must manage Gamma, Vega, Theta, and Rho. Gamma measures the rate of change of Delta, indicating how frequently the hedge needs adjustment.

Vega measures the sensitivity to changes in implied volatility. Theta measures the time decay of the option's value.

Rho measures the sensitivity to changes in interest rates. Effective risk management requires monitoring and managing all these factors.
