Zomma, also known as DgammaDvol, is a financial term that refers to the rate of change of an option’s gamma with respect to changes in the implied volatility of the underlying asset. It is a third-order Greek, meaning it measures the sensitivity of the option’s price to multiple factors. In simpler terms, zomma helps traders and investors understand and measure the risk associated with the change in both the option’s price and implied volatility.


The phonetic pronunciation of “Zomma” would be: /ˈzɒmə/ or Z as in Zulu, O as in Oscar, M as in Mike, and A as in Alpha.

Key Takeaways

  1. Zomma is a measurement of the rate of change in gamma concerning a change in implied volatility. It is a third-order derivative and sometimes referred to as “Dprofil/Dvol” or “Vomma.”
  2. It helps option traders to estimate the changes in an option’s gamma as the market’s perceived volatility changes. This is particularly useful in understanding the potential change in an options position’s risk profile as volatility shifts.
  3. Zomma is most significant for options that are deep in-the-money or far out-of-the-money, as these options tend to have higher gamma values. Hence, an accurate assessment of Zomma can help traders plan their strategies and manage risk effectively.


Zomma, an important term in business and finance, is a third-order Greek measure used to assess the risk associated with options trading, specifically the rate of change of gamma in response to changes in the underlying asset’s volatility. This higher-order derivative is crucial for options traders as it allows them to better manage their positions by anticipating how the sensitivity of an option’s gamma to price fluctuations will be affected. By understanding and monitoring Zomma, investors can actively hedge their options positions more effectively, navigate potential changes in market conditions, and optimize their overall risk-reward balance in options trading. Ultimately, Zomma plays a vital role in enhancing the precision and success of options risk management strategies.


Zomma is a vital risk efficiency metric in the world of finance and mathematics, specifically in the domain of options trading. It refers to the third-order Greek, which measures the rate of change in an option’s gamma with respect to changes in the underlying asset’s volatility or price fluctuations. Essentially, zomma enables traders and portfolio managers to monitor and understand how the gamma of an option will respond as the volatility of the underlying asset changes. This greater awareness allows them to adjust their strategies and hedge their positions more effectively in a dynamic market environment, thus mitigating any potential risks arising from swings in the market. For those engaged in options trading, grasping the concept of zomma is crucial because it offers valuable insights for risk management and strategic decision-making. It is particularly relevant when dealing with complex or exotic options. By recognizing the changes in gamma and how they respond to volatility, traders are better equipped to create tailored strategies, leverage arbitrage opportunities, and hedge their overall positions to minimize potential losses. Zomma, therefore, serves as a critical tool for managing the risk profile of an options portfolio, ensuring that market players have the necessary information to make well-informed decisions and better navigate volatile financial markets.


Zomma is a third-order Greek term used in options trading, which measures how much the gamma of an option changes with respect to volatility and the price of the underlying asset. Real-world examples specific to Zomma are scarce because of its high-level usage by advanced traders and institutional investors, but below are three scenarios indirectly related to Zomma. 1. Implied Volatility ChangesIn times of market turbulence, implied volatility often increases, causing the Zomma for options to change. For instance, when the COVID-19 pandemic hit in March 2020, markets became highly volatile. Advanced options traders and institutional investors who were managing their portfolio risk using Zomma would have had to pay close attention to both the gamma and Vega of their option positions during this time. 2. Large Gap Moves in StocksWhen a company announces unexpected good or bad news, like quarterly earnings or a breakthrough product, it may cause a significant gap move in the stock price. In such situations, Zomma helps options traders understand the rate at which their option’s gamma reacts to these large movements and helps them manage their risk exposure accordingly. 3. Strategies with Higher-Order GreeksProfessional traders or hedge funds might employ trading strategies involving higher-order Greeks like Vomma, Zomma, and Volga to capitalize on the market edge available due to options mispricing or the anticipation of large, rapid price moves. These sophisticated traders might take advantage of the Zomma by performing analysis on various options and selecting the ones that provide the best risk-reward ratio based on the position’s sensitivity to underlying price moves and changes in implied volatility.

Frequently Asked Questions(FAQ)

What is Zomma?
Zomma is a financial term referring to the third-order Greek derivative that measures the rate of change of gamma concerning changes in the implied volatility of an option. Essentially, it represents the sensitivity of Gamma to movements in implied volatility.
How is Zomma calculated?
Zomma can be calculated using the formula:Zomma = (d²Gamma / dVolatility²) * (1 / option_price)Here, Gamma is the second-order Greek option price sensitivity that measures the rate of change of delta against the spot price of the underlying asset, and Volatility refers to the implied volatility.
Why is Zomma important in the context of option trading?
Zomma is important because it helps option traders to measure and manage the risk associated with changes in both the underlying asset price and implied volatility. A more significant change in Zomma suggests a higher sensitivity, which can significantly impact the options position and eventually affect the potential profits or losses.
How does Zomma relate to other Greeks?
Zomma is a third-order Greek derived from Gamma and Volatility. Other important Greeks include Delta (first-order) representing the rate of change of the option price relative to the underlying asset price, Vega representing the rate of change of the option price concerning the implied volatility, and Theta, which refers to the rate of change of the option price considering time decay.
How can option traders use Zomma in managing their options positions?
Option traders can use Zomma to understand the potential risk associated with their options positions and constantly monitor Zomma’s value to adjust their trading strategies accordingly. By considering the changes in Zomma along with other Greeks, option traders can better manage their positions for optimal risk-return balance.
