Copula-Based Price Risk Hedging Models

Abstract

The article deals with the issue of copula use in the program of market risk hedging. Copula-models performance is compared to the OLS-based ones. Fully parametric and semi-parametric approaches to copula-modeling are investigated. The copula-based models efficiency is illustrated by the fact of decreasing the daily profit-and-loss volatility of the hedged portfolio by simultaneously augmenting its total yield compared to the OLS-based hedge ratio computation during the back-testing period. Never-the-less, it is shown that copula-based approaches are able to outperform OLS-based ones only for direct hedging programs, while for cross-hedging ones OLS do bettercopula; direct hedging; cross hedging; hedge ratio
