چکیده

Recent literature discusses the persistence of skewness and tail risk in hedge fund returns. The aim of this paper is to suggest an alternative skewness measure  which is derived as the normalized shape parameter from the skew-normal distribution. First, we illustrate that the skew-normal distribution is better able to catch the characteristics of hedge fund returns than the normal distribution. And second, we show that using the skewness parameter  has a number of advantages compared to common measures of skewness, e.g., it has a limpid financial interpretation as a skewness shock on normally distributed returns and tail-risk measures such as Value-at-Risk and Conditional Value-at-Risk are decreasing functions of  . JEL Classification: G10, G11, G23, G29

An Excursion Into The Statistical Properties of Hedge Fund Returns

This paper provides an overview of the most important statistical properties of individual hedge fund returns. We find that the net-of-fees monthly returns of the average individual hedge fund exhibit significant skewness, excess kurtosis, as well as positive first-order serial correlation. The correlations between hedge funds in the same strategy group are of a similar order of magnitude as th...

The Statistical Properties of Hedge Fund Index Returns and Their Implications for Investors

The monthly return distributions of many hedge fund indices exhibit highly unusual skewness and kurtosis properties as well as first-order serial correlation. This has important consequences for investors. We demonstrate that although hedge fund indices are highly attractive in mean-variance terms, this is much less the case when skewness, kurtosis and autocorrelation are taken into account. Sh...

Sharpe Ratio for Skew-Normal Distributions: A Skewness-Dependant Performance Trade-Off

Main academic criticism on the Sharpe ratio concerns its lack in incorporating skewness in performance evaluation. In this note we rewrite the classical Sharpe ratio for skew normal distributions. This new skew-normal Shape ratio consistently moves with skewness and no distorted information on performance is provided. An empirical investigation illustrates skew-normality of mutual and hedge fun...

Effect of booms or disasters on the Sharpe Ratio

The purpose of this paper is to analyze the effect of either booms or disasters on the Sharpe Ratio. We provide a closed form expression of the Sharpe Ratio of an index whose log-return follows an arbitrary distribution. That is, besides variance, we allow for skewness, kurtosis and higher cumulants of the log-return to be non-zero. Our article has two main contributions. First, the Sharpe Rati...
