The aim of this research paper is to evaluate hedge fund returns Value-at-Risk by using GARCH models. To perform the empirical analysis, one uses the HFRX daily performance hedge fund strategy subindexes and spans the period March 2003-March 2008. I found that skewness and kurtosis are substantial in the hedge fund returns distribution and the clustering phenomenon is pointed out. These features suggest the use of GARCH models to model the volatility of hedge fund return indexes. Hedge fund return conditional variances are estimated by using linear models (GARCH) and non-linear asymmetric models (EGARCH and TGARCH). Performance of several Value at Risk models is compared; the Gaussian VaR, the student VaR, the cornish fisher VaR, the normal GARCH-type VaR, the student GARCHtype VaR and the cornish fisher GARCH-type VaR. Our results demonstrate that the normal VaR underestimates accurate hedge fund risks while the student and the cornish fisher GARCH-type VaR are more reliable to estimate the potential maximum loss of hedge funds.

The subprime crisis, which proved devastating for the hedge fund industry, induced significant losses for investors who ploughed into absolute return funds. In such a context, investigating the opacity surrounding the hedge fund industry and its prohibitive fee structure is of real interest as, within the context of the Madoff scandal, there is strong evidence of a reduction in investor confidence. On the other hand, investors are still looking for attractive returns. Hedge fund clones therefore appear to offer a promising solution as they seek to replicate hedge fund returns at lower fees and with more transparency and liquidity.
