What Is “Slippage” and How Does It Affect the Cost of Gamma Hedging?

Slippage is the difference between the expected price of a trade and the price at which the trade is actually executed. It affects the cost of Gamma hedging by increasing the total transaction cost.

When a market maker frequently trades the underlying asset to adjust their Delta (Gamma hedging), slippage on each trade accumulates, making the overall cost of maintaining the hedge significantly higher than anticipated.
