The Art of Gamma Scalping on Deribit

Gamma scalping is a dynamic hedging technique used by options traders to profit from the volatility of the underlying asset while maintaining a delta-neutral position. It is a hands-on, active strategy that requires constant monitoring and adjustment, but for those who master it, it can be a consistent source of income, especially in the choppy, volatile crypto markets. This article will explain the mechanics of gamma scalping and how to implement it on Deribit.

Understanding Gamma

Before we can talk about gamma scalping, we need to understand gamma. Gamma is one of the "Greeks," a set of risk metrics used to measure the sensitivity of an option's price to various factors. Specifically, gamma measures the rate of change of an option's delta. Delta, in turn, measures the change in an option's price for a one-unit change in the price of the underlying asset.

In simpler terms, if delta is the "speed" of an option's price, then gamma is the "acceleration." A long option position (either a call or a put) will always have positive gamma. This means that as the price of the underlying asset moves in your favor, your delta will increase, and your position will become more profitable at an accelerating rate. Conversely, as the price moves against you, your delta will decrease, and your losses will decelerate.

The Mechanics of Gamma Scalping

Gamma scalping is the process of monetizing this positive gamma. The basic idea is to start with a delta-neutral, long-gamma position, such as a long straddle (long a call and a put at the same strike). As the price of the underlying asset moves, your delta will change. To maintain your delta-neutral position, you need to hedge by trading the underlying asset.

Here's how it works in practice:

1. Establish a Long-Gamma, Delta-Neutral Position: The classic example is a long straddle. You buy a call and a put with the same strike and expiration. At initiation, this position will be approximately delta-neutral.

2. Hedge as the Price Moves: As the price of the underlying asset moves, your delta will change. For example, if the price goes up, your long call will become more delta-positive, and your long put will become less delta-negative, resulting in a net positive delta for your position. To get back to delta-neutral, you need to sell the underlying asset.

3. Profit from the Scalps: You are now short the underlying asset. If the price reverts and moves back down, you can buy back the underlying at a lower price, locking in a profit. This is the "scalp." You have profited from the small fluctuation in the price of the underlying.

4. Repeat: You continue this process, buying the underlying when the price falls and selling it when the price rises, always maintaining a delta-neutral position. Each time you buy low and sell high, you are locking in a small profit. These small profits, accumulated over time, are your gamma scalping profits.

The P&L of a Gamma Scalp

The profitability of a gamma scalping strategy depends on the relationship between the implied volatility of the options you bought and the realized volatility of the underlying asset. The cost of your long-gamma position is the time decay, or theta. You are paying theta every day to maintain your position. Your profits come from the scalps you are making. If the realized volatility of the underlying is high, you will be able to make many profitable scalps, and your profits will exceed your theta decay. If the realized volatility is low, you will not be able to make enough scalps to cover your theta, and you will lose money.

In essence, when you are gamma scalping, you are long volatility. You are betting that the realized volatility of the underlying will be greater than the implied volatility that you paid for when you bought the options.
