An empirical analysis of dynamic multiscale hedging using wavelet decomposition (2011)

Abstract This paper investigates the hedging effectiveness of a dynamic moving window OLS hedging model, formedusing wavelet decomposed time-series. The wavelet transform is applied to calculate the appropriate dynamicminimum-variance hedge ratio for various hedging horizons for a number of assets. The effectiveness of thedynamic multiscale hedging strategy is then tested, both in-and out-of-sample, using standard variance reductionand expanded to include a downside risk metric, the time horizon dependent Value-at-Risk. Measured usingvariance reduction, the effectiveness converges to one at longer scales, while a measure of VaR reduction indicatesa portion of residual risk remains at all scales. Analysis of the hedge portfolio distributions indicate that thisunhedged tail risk is related to excess portfolio kurtosis found at all scales.
