Empirical Analysis of the Performance of Stock-style Open-ended Funds

By applying the Sharpe indexing method, OLS analysis method based on cross-sectional data and H-M method, this paper makes a relatively comprehensive evaluation of the stock-style open-ended funds＇ profitability, the persistence of fund earn- ing and the ability of fund manager in terms of stock picking and time selection. The results show the overall performance of the domestic stock-style open-ended funds outstands that of the market benchmark portfolio. The results also suggest that the persist- ence of fund earning is not very obvious, and that the fund manager lacks the ability of stock picking and time selection. On this basis, the paper makes an overall assessment of the stock-style open-ended fund performance and then comes up with the sugges- tion as to the promotion of stock-style open-ended fund market development.
