From Wikipedia, the free encyclopedia
In finance, a volatility swap is a forward contract on the future realised volatility of a given underlying asset. Volatility swaps allow investors to trade the volatility of an asset directly, much as they would trade a price index.
The underlying is usually a foreign exchange (FX) rate (very liquid market) but could be as well a single name equity or index. However, the variance swap is preferred in the equity market due to the fact it can be replicated with a linear combination of options and a dynamic position in futures.
