Mastering Dealer Gamma Exposure Options: A Personal Journey
As a trader, I’ve always been fascinated by the intricate world of options. One aspect that has particularly caught my attention is dealer gamma exposure. In this article, I’ll share my personal experiences, practical insights, and lessons learned from navigating the complex landscape of dealer gamma exposure options.
What is Dealer Gamma Exposure?
Before we dive into the practical aspects, let’s quickly define what dealer gamma exposure is. Gamma exposure refers to the rate of change of an option’s delta with respect to the underlying asset’s price. In other words, it measures how much the option’s sensitivity to price changes will change when the underlying asset’s price moves. Dealer gamma exposure, specifically, refers to the aggregate gamma exposure of an options dealer’s entire book.
My Introduction to Dealer Gamma Exposure
I still remember the first time I encountered dealer gamma exposure. I was working as a junior trader at a small proprietary trading firm, and our senior trader, Alex, would often mention the importance of managing gamma exposure. At first, I didn’t understand the significance, but as I delved deeper, I realized that it was a crucial aspect of our risk management strategy.

Understanding the Greek Gods
To truly grasp dealer gamma exposure, you need to understand the Greeks: delta, gamma, theta, and vega. Delta measures the rate of change of an option’s price with respect to the underlying asset’s price. Gamma, as mentioned earlier, measures the rate of change of an option’s delta. Theta represents the rate of change of an option’s price with respect to time, and vega measures the rate of change of an option’s price with respect to volatility.

Practical Applications of Dealer Gamma Exposure
Gamma Scalping
Identify high-gamma options with low volatility
Buy calls and puts with high gamma exposure
Sell options with lower gamma exposure to hedge
Monitor and adjust positions as gamma exposure changes
During the 2020 COVID-19 pandemic, I noticed that the VIX index was skyrocketing, causing option prices to increase dramatically. I decided to buy calls and puts on a highly volatile stock, knowing that its gamma exposure would increase as the underlying price moved. I then sold options on a less volatile stock to hedge my position. As the stock price moved, my gamma exposure changed, and I adjusted my positions accordingly, profiting from the gamma scalping strategy.
