基于超高阶矩的SE-DEA模型的股票型基金绩效分析
首发时间:2018-05-24
摘要:基金风险的度量一般都是基于四阶及以下矩风险,忽略了极端风险对于基金绩效的影响。本文建立了一个基于超高阶矩的SE-DEA基金绩效考核模型,将涵盖了四阶以上矩风险的AS与FH指数引入对基金业绩的评价中,以考察超高阶矩风险对基金绩效评估的影响。本文通过对我国股票型基金业绩的实证研究,发现考虑了四阶以上超高阶矩后挑选出的基金比只考虑传统方差、偏度以及峰度得到的基金有效性更高,更能全面反映出股票型基金面临的风险。研究还发现,尽管风险是影响投资者挑选基金的最重要因素,但从改进基金绩效而言,基金管理人如何提高择股择时能力更是当务之急。

Performance Analysis of Stock Funds in China which based on SE-DEA model with ultra-high-order moments
Abstract:The measurement of fund risk is generally based on moment risk of the fourth order and below, ignoring the impact of extreme risk on fund performance. This paper establishes a SE-DEA fund performance appraisal model based on ultra-high-order moments, introduces the AS and FH indices covering moment risk of more than fourth order into the performance evaluation of the fund, in order to investigate the effect of ultra-high-level moments on the fund performance evaluation Impact. Through the empirical research on the performance of equity funds in our country, we find that the funds selected after considering the fourth-order ultra-high moments are more effective and more comprehensive than the funds only considering the traditional variance, skewness and kurtosis.
