Variance Swap

Variance Swap

A forward contract on the variance of a security. The variance is the square of the standard deviation. As a result, the payout on a variance swap is higher when the volatility increases. A variance swap allows the investor to speculate on volatility, just as a trader might speculate on the price of a stock; it is most advantageous when the volatility is or is expected to be high.

To further examine the side effects of using the noisier [DELTA][c.sub.t], I consider variance swaps.
