How Can a Market Maker Hedge Their Gamma Exposure?
A market maker can hedge their gamma exposure by trading options with offsetting gamma. If they are short gamma, they can buy options (which are long gamma) to reduce the portfolio's overall gamma to zero or a manageable level.
They typically use options that are close to the money or have short-term maturities, as these have the highest gamma.
