Carr and Wu show that we can replicate the payoff from the variance swap
rate in which the contracted payoff depends on the difference between the pre-fixed variance swap
rate and the realized return variance that is computed ex post by using out-of-money option prices.
However, the variance swap
is reliable in the index market because it can be replicated with a linear combination of options and a dynamic position in futures.
The new S&P 500 Variance futures contract is designed to offer benefits to both current OTC users as well as to customers who have not traditionally participated in the OTC variance swap
To further examine the side effects of using the noisier [DELTA][c.sub.t], I consider variance swaps
. In this forward contract, two counterparties agree to settle the difference between a floating variance [[sigma].sub.R.sub.2], which is realized over the life of the contract, and a fixed variance swap
of Calgary) introduces mathematical equations for modeling the price of swaps in the financial and energy markets with different stochastic volatilities, and presents a variance drift adjusted version of the Heston model which improves the market volatility surface fitting.The graduate textbook explores variance and volatility swaps for financial markets with underlying assets following the Heston model, the valuation of variance swaps
for stochastic volatilities with delay, a semi-Markov modulated market consisting of a riskless bond and a risky stock, variance and volatility swaps for volatilities driven by fractional Brownian motion, and explicit option pricing of a mean-reverting asset in energy markets.

They have removed the need for investors to trade volatility through variance swaps
Mr Parkes points a finger "variance swaps
", arcane contracts based not on the way the market is going to move, but on how much it jumps about in either direction.
This has led to arcane derivatives knows as "variance swaps
", bets, if you like, on the volatility of an investment.
