Vega
The sensitivity of an option price to changes in volatility.
Detail
Vega shows how much the option price will change if the implied volatility (IV) changes by 1%. For example, a vega of 0.10 means that if the IV increases by 1%, the option price will increase by $0.10.
Vega measures the effect of changes in volatility on the option price. Important for strategies that bet on the rise/fall of IV. A higher vega means that the option price will be more sensitive to changes in volatility. Long-term options (LEAPS) have higher vega, close to expiration the vega is low.
Optimal conditions
When expecting an increase in IV (buying options) or a decrease in IV (writing options). High IV = high vega, low IV = low vega.
Max profit
