Definition
Vega Neutral refers to a trading strategy used by options traders to manage risk associated with changes in implied volatility. This approach seeks to establish a position where the net vega of the options portfolio is zero, meaning the overall sensitivity of the portfolio’s value to changes in volatility has been neutralized, thus protecting profits from volatility fluctuations.
Vega vs. Other Greeks
| Greek | Definition | Main Focus |
|---|---|---|
| Vega | Measures the sensitivity of an option’s price to changes in implied volatility. | Volatility Sensitivity |
| Delta | Measures the sensitivity of an option’s price to changes in the price of the underlying asset. | Price Sensitivity |
| Gamma | Measures the rate of change of delta in response to price changes of the underlying asset. | Delta Acceleration |
| Theta | Measures the time decay of an option’s price, or the amount of value an option loses as it approaches expiration. | Time Decay |
| Rho | Measures the sensitivity of an option’s price to changes in interest rates. | Interest Rate Sensitivity |
How Vega Neutral Works
To create a vega neutral position, traders typically use a combination of long and short options. For example:
- Long Calls and Puts: If a trader anticipates an increase in volatility, they may purchase an equal number of calls and puts.
- Short Options: Conversely, if the expectation is a decrease in volatility, a trader might sell options to offset their vega exposure.
An example could illustrate how traders neutralize vega:
- If you own a portfolio of options with a net positive vega (indicating sensitivity to an increase in volatility), you might sell a few call options or buy put options to adjust your exposure to zero.
Vega Neutral Formula:
Here’s a simple representation as a formula:
Net Vega = Vega Long Options - Vega Short Options = 0
