Definition & Meaning

Vega is a financial term that indicates how sensitive the price of an option is to changes in the volatility of the underlying asset. Specifically, it measures the amount by which the price of an option is expected to change for a one-percent change in the underlying asset's volatility. Understanding vega is crucial for traders and investors, as it helps them assess the risk associated with options trading.

Real-world examples

Here are a couple of examples of abatement:

For instance, if an option has a vega of 0.2, this means that if the volatility of the underlying asset increases by one percent, the price of the option is expected to increase by 0.2 units (hypothetical example). Another example is when traders adjust their portfolios based on anticipated changes in market volatility, using vega to gauge potential price movements.
