This measures the sensitivity of an option’s premium to a one-unit change in the implied volatility of the underlying asset, representing a key second-order risk factor. A positive vega means the option price increases as expected volatility rises, a desirable position during uncertain market conditions. Managing this exposure is crucial for option portfolio performance.
Hedging
Traders actively manage this risk by taking offsetting positions in other options or volatility instruments to neutralize the portfolio’s overall sensitivity to shifts in the implied volatility surface. This requires continuous monitoring of implied volatility dynamics.
