Variance Swap Replication

Methodology

Variance swap replication is a methodology used to construct a synthetic variance swap position by dynamically trading a portfolio of options, typically out-of-the-money puts and calls. This technique leverages the relationship between option prices and implied volatility to mimic the payoff of a variance swap. The replication process requires continuous rebalancing of the options portfolio to maintain a delta-neutral position. It provides a robust method for hedging or speculating on future realized volatility.
