摘要

随着中国金融市场的发展,混合型共同基金以其投资对象多样化、风险适中、基金资产收益率客观等特点受到市场的青睐。本文旨在分析中国混合共同基金的管理能力,特别是选股能力和择时能力。在此基础上,本文分别采用Jensen alpha模型和Treynor-Mazuy模型(T-M模型)对基金经理的选股能力和择时能力进行了评估。运用Jensen的alpha和T-M模型对中国现有的415只混合共同基金样本进行实证分析。实证结果表明:a)大多数共同基金经理在样本期内具有较强的选股能力,但择时能力较弱;B)他们中的一些人有能力选择表现优于市场的股票,并把握市场时机;c)上述能力与中国混合共同基金市场的基金规模呈正相关。混合共同基金在中国已成为越来越受欢迎的投资对象,本文有助于定量评估这一金融工具的表现。

Study on Timing and Selectivity of China’s Hybrid Mutual Funds
With the development of China's financial market, hybrid mutual funds have been favoured by the market because of their features of diversified investment objects, moderate risk and objective return rate of fund assets. This paper aims to analyze the management ability of China's hybrid mutual funds, particularly stock selection and timing ability. On this basis, the paper employs Jensen alpha model and Treynor-Mazuy Model (T-M model) to assess fund managers' stock selection and timing abilities respectively. It empirically implements Jensen's alpha and T-M model to samples of 415 China's existing hybrid mutual funds. The empirical results indicate that a) most of the mutual fund managers own strong stock selection abilities during the sample period but weak timing abilities; b) some of them have the abilities to select stocks outperformed the market as well as to time the market; c) the above abilities are positively related to the fund size in China's hybrid mutual fund market. Hybrid mutual funds in China have become an increasingly popular investment target and this paper helps to assess the performance of this financial instrument quantitatively.
