摘要
基金经理是否具有行业选择能力,是研究基金经理投资管理能力的重要内容。基金股票组合的行业集中度能够度量基金股票组合的行业配置比例偏离市场组合的行业市值比例的程度,能够反映基金经理投资过程中的行业选择行为。对中国积极管理的股票型基金的实证结果表明,基金经理对行业的主动选择并未带来更高的超额收益,基金经理整体上没有行业选择能力。运用Grinblatt和Titman提出的GT指标在单只基金层面基础上对基金经理行业选择能力的研究,也发现基金经理整体上并不具有行业选择能力。
Active fund managers can exhibit their investment ability through stock selection, market timing and industry selection. Portfolio industry concentration can reflect the industry selection behavior of fund manager. The empirical analysis on the open-end equity fund in China shows that fund manager' s active selection of portfolio industry allocation can not bring about better fund performance. Thus fund managers have no industry selection ability. Moreover, the analysis by applying the Grinblatt and Titman' s GT measure to individual fund do not support that managers have industry selection ability.
