绩效评估指数是评估各种投资结果的一种重要方式.为克服现有指数的不足,通过更加细致地划分收益与损失,提出了一种新的绩效评估指数,它不仅能精细刻画基金收益的分布特性,而且可恰当反映投资者的不同风险厌恶程度.实证结果表明,新指数确实能更好地区分基金的表现,并能给出更加全面、可靠的绩效排名.
The performance evaluation index is an important way to evaluate the performance of investment portfolios. In order to avoid the shortcomings of current performance evaluation indexes, a new index is pro- posed by more precisely dividing return and risk. The new index can not only describe in detail the distribution characteristics of mutual fund returns, but also reflect investors' different attitudes toward risk and reward. Empirical results with Chinese closed-end fund data confirm the effectiveness of the new index, and its strong ability in better separating funds and providing a more comprehensive and reliable ranking.
