Is VIX a variance swap?

Regardless its legacy name as a volatility index, VIX is calculated as a variance swap. Unlike an actual swap, variance swap is a forward contract on realized variance. VIX calculation formula, as outlined in The VIX White Paper (CBOE, 2009), is a discretization of the theoretical pricing result.

People also ask, how does a variance swap work?

A variance swap is when two parties hedge on the underlying volatility of an asset. It is similar to an interest rate swap in that two parties exchange payments based on the underlying asset's price changes. If realized volatility is more significant than strike, then payoffs at maturity are positive.

Likewise, what moves the VIX? Volatility value, investors' fear and the VIX index values move up when the market is falling. One should also note that VIX movement is much more than that observed in the index. For example, when S&P 500 declined around 15% between August 1, 2008 and October 1, 2008, the corresponding rise in VIX was nearly 260%.
