What is Vega?Vega refers to the change in the price of an option for a $1 change in the volatility of the underlying asset.
Vega is a Greek letter that measures the sensitivity of an option's price to changes in volatility. It is calculated by multiplying the option's delta by the square root of the time to expiration and dividing by 100. Vega is positive for call options and negative for put options.
Vega is important because it can help investors to manage risk. For example, if an investor is long a call option, they will benefit from an increase in volatility. This is because the value of the call option will increase as volatility increases. Conversely, if an investor is short a call option, they will lose money if volatility increases.
Vega can also be used to create trading strategies. For example, an investor could buy a call option with a high vega and sell a call option with a low vega. This would create a synthetic position that would benefit from an increase in volatility.

Calculation
The formula for calculating vega is important because it allows us to understand the relationship between vega and the other Greek letters. Delta measures the sensitivity of an option's price to changes in the underlying asset's price. Time to expiration measures the amount of time remaining until the option expires. Volatility measures the volatility of the underlying asset's price.
Vega is positively correlated with delta and time to expiration. This means that as delta and time to expiration increase, vega will also increase. Vega is negatively correlated with volatility. This means that as volatility increases, vega will decrease.
The relationship between vega and the other Greek letters can be used to develop trading strategies. For example, if an investor believes that volatility is going to increase, they could buy an option with a high vega. This would allow them to profit from the increase in volatility.
