Option Vega is a hedge parameter, one of the so-called Greeks. It measures the rate of change of option price in response to changes in implied volatility of the underlying instrument. In mathematical sense, delta is the first derivative of option price with respect to implied volatility.

Vega is always positive for long option posiions; it is typically highest for at-the-money options.
