Vega Sensitivity Assessment

Definition

Vega sensitivity assessment quantifies an option’s responsiveness to changes in the implied volatility of its underlying asset. Vega measures the expected change in an option’s price for a one-percentage-point increase in implied volatility, holding all other factors constant. Higher Vega values indicate that an option’s price will move more significantly with shifts in market expectations of future price fluctuations. It is a crucial Greek for risk analysis.
