How Can a Trader Profit from a Change in Implied Volatility?

A trader can profit from a change in implied volatility (IV) by taking a position with positive or negative Vega. A buyer (long option) profits if IV increases (long Vega), and a seller (short option) profits if IV decreases (short Vega).

This is often done using strategies like straddles or strangles.
