| Abstract: | In this paper, the theory of simplicial depth function is introduced. By ameliorating Sharpe Index Formula and utilizing one of characteristics of simplicial depth function median which possesses robustness, we apply depth function median to ameliorated Sharpe Index Formula, order domestic closed fund and classify them in different star level, then we contrast our result with Zhongxin Star Level and Sample Star Level. At last, by defining Fund Performance Bias Degree, we bring forward the idea that Fund Performance Bias Degree can be used to appraise the capacity of each fund to catch market chance. |
