What is Vega

Vega is a ratio that measures the rate of change in an option’s price to the change of implied volatility in the underlying security. In effect, it is a measure of an option’s sensitivity to volatility.

With an option that has a vega of 0.10, if implied volatility changes by 1 percent, the option's value is expected to change by 10 cents. Long-dated options have positive vega while options nearing expiration have negative vega.

Vega is useful for hedging against changes in implied volatility. Changes in vega can be measured by using vomma, a minor Greek.

Vega is one of the first-order Greeks or major Greeks. Vega is also known as kappa, tau or zeta.
