Definition of Vomma
Vomma is the measure of the sensitivity of the vega of an option to changes in the volatility of the underlying asset. It represents how much vega (the option’s sensitivity to volatility) will change as there are variations in market volatility. Vomma is recognized as a second-order derivative, providing insights into the convexity of an option’s vega. Essentially, it is crucial for traders to understand how vega itself evolves when volatility fluctuates!
Vomma vs. Vega
| Feature | Vomma | Vega |
|---|---|---|
| Definition | Sensitivity of vega to changes in volatility | Sensitivity of option price to volatility |
| Order of Derivative | Second-order | First-order |
| Measurement Units | Change in vega per 1% volatility change | Change in option price per 1% volatility |
| Importance | Understanding the curvature of vega | Measuring option sensitivity to volatility |
Examples of Vomma
-
Example 1: If an option has a vega of 0.05 and vomma of 0.10, this means that if volatility increases by 1%, the vega increases to 0.06 (an increase of 0.01).
-
Example 2: Consider a scenario where volatility is initially low; the vomma will help determine how vega may increase much more aggressively as market conditions cause volatility to ramp up.

Fun Facts about Vomma

“Why did the option trader break up with volatility? Because it was too sensitive!” 😄

Vomma is like the zesty sidekick to vega—it might not always be center stage, but it sure gets the party started when things get wobbly!

Frequently Asked Questions
Q1: Why is Vomma important for options traders?
A: Vomma helps traders understand how their sensitivity to volatility (vega) will react as market conditions change, allowing for more informed trading strategies.
Q2: Is high vomma always a good thing?
A: Not necessarily! High vomma indicates high sensitivity to volatility, which may increase potential losses during turbulent markets; it’s a double-edged sword!
Q3: How do I calculate Vomma?
A: Unfortunately, you can’t just plug it into your favorite calculator app; vomma is typically derived from complex models that account for various factors in options pricing.
