Definition of Zomma
Zomma is a third-order risk measure that signifies the extent to which the gamma (the rate of change of delta) of an option changes in response to fluctuations in implied volatility (IV) of the underlying asset. Unlike traditional Greek letters used in option pricing, “Zomma” is a tongue-in-cheek term coined by traders to give it an air of gravitas while evoking the sound of Greek characters. The higher the zomma, the more sensitive gamma is to shifts in implied volatility, translating small changes into large impacts.
Zomma vs Other Minor Greeks
| Feature | Zomma | Vomma |
|---|---|---|
| Definition | Sensitivity of gamma to IV changes | Sensitivity of vega to IV changes |
| Order | Third-order measure | Also third-order measure |
| Impact on Gamma | High zomma means high sensitivity | High vomma means volatility sensitivity |
| Relation to Delta | Affects delta indirectly via gamma | Affects delta via the sensitivity of vega |
| Use Case | Detailed risk management | Manage options with volatility exposure |
Examples
- A very high zomma indicates that small changes in IV could drastically affect gamma, leading to unpredictable price movements in an option’s price.
- Conversely, a low zomma suggests that changes in IV will have little impact on gamma, indicating a more stable option position.
Related Terms
- Gamma: The measure of the rate of change of an option’s delta.
- Vega: Represents the sensitivity of an option’s price to changes in the volatility of the underlying asset.
- Delta: Indicates how much an option’s price will move for a dollar change in the underlying asset’s price.
Formula
Although Zomma itself doesn’t have a widely-used formula, its conceptual foundation can be explored via the derivatives of other Greeks.
