While the main focus of this article is a style analysis of hedge fund strategy in terms of performance measurement, the main point in this paper is to find out what kind of hedge fund strategy will be most suitable for both risk-averse and risk-seeking investors when the normal distribution of return in hedge funds is not valid. The author uses a skewness/kurtosis ratio in order to contribute to the accuracy of performance measurement and proposes a new ratio (prospect ratio) to replace the existing Sharpe and Sortino ratios.
