Equity volatility: Betting on turbulence
Equity volatility: The technicalities of a variance swap
Buying up-variance: If the underlying price is expected to rise or stay above a given level then buying an up-variance swap (with a 95% trigger for example) is a cheaper alternative to a long variance swap position because it has a lower break-even and a lower cost of carry. A relative value trade using an up-variance swap would consist of buying up-variance and selling a variance swap with the same maturity in order to capture the difference in strikes.
Selling down-variance: If the underlying is expected to stay below a given level then selling a down-variance swap (with a 105% trigger for example) could be more attractive than selling a variance swap because it has a higher strike, and therefore higher carry, and a higher break-even.
