Market maker re-hedging is the continuous action of adjusting a market maker’s portfolio to maintain a neutral or desired risk profile. This involves buying or selling the underlying asset or other derivatives to offset changes in the market maker’s options positions. The frequency and magnitude of these adjustments depend on market volatility and the portfolio’s gamma exposure. It is a dynamic process.
Risk
The primary purpose of re-hedging is to manage the various risks inherent in market making, particularly delta and gamma risk. As the underlying asset’s price changes, the delta of the market maker’s options portfolio shifts, creating unwanted directional exposure. Re-hedging mitigates this risk by bringing the portfolio’s delta back to a desired level. Without consistent re-hedging, market makers face substantial losses. This proactive risk management is essential.
Adjustment
Re-hedging constitutes a series of tactical adjustments to the market maker’s inventory and derivative positions. These adjustments are triggered by changes in the underlying asset price, implied volatility, or time decay. Automated systems are often employed to execute these adjustments rapidly and efficiently. The cost of these adjustments, including transaction fees and slippage, impacts the profitability of market making operations. Optimal adjustment frequency is a complex calculation.
