Risk Measures for Autocorrelated Hedge Fund ReturnsAntonio Di CesareBank of Italy Philip A. StorkVU University Amsterdam - Faculty of Economics and Business Administration; Duisenberg School of Finance Casper G. De VriesErasmus University Rotterdam (EUR) - Erasmus School of Economics (ESE); Tinbergen Institute; CESifo (Center for Economic Studies and Ifo Institute for Economic Research) October 14, 2011 Bank of Italy Temi di Discussione (Working Paper) No. 831 Abstract: Standard risk metrics tend to underestimate the true risks of hedge funds because of serial correlation in the reported returns. Getmansky, Lo, and Makarov(2004) derive mean, variance, Sharpe ratio, and beta formulae adjusted for serial correlation. Following their lead, we derive adjusted downside and global measures of individual and systemic risks. We distinguish between normally and fat tailed distributed returns and show that adjustment is particularly relevant for downside risk measures in the case of fat tails. A hedge fund case study reveals that the unadjusted risk measures considerably underestimate the true extent of individual and systemic risks.
