Market maker inventory refers to the holdings of underlying assets and derivatives maintained by market makers to facilitate trading and provide liquidity. This inventory includes both long and short positions in various assets, which are constantly adjusted to meet market demand. Effective inventory management is crucial for minimizing risk exposure and maximizing profitability.
Management
Inventory management involves balancing the market maker’s position to maintain a neutral risk profile, often through delta hedging. When a market maker sells an option, they acquire a short position in the underlying asset to offset the delta risk. The inventory level dictates the market maker’s ability to quote prices and absorb large orders without incurring significant losses.
Risk
Inventory risk arises from holding assets subject to price fluctuations, particularly in volatile crypto markets. Market makers face the challenge of managing inventory in real-time, as rapid price changes can quickly render a position unprofitable. The cost of re-hedging and potential slippage are key considerations in managing this risk.
