破解“基金赚钱、基民不赚钱”之谜——基于投资者行为偏差的解释

Solving the Puzzle of "Funds Make Money, But Fund Investors Do not": An Explanation Based on Investor Behavioral Biases

  • 摘要: 中国主动管理型公募基金收益率较好,但“基金赚钱、基民不赚钱”的异象频现。本文基于投资者行为偏差视角,选取开放式偏股型主动管理基金为样本,实证检验了基金投资者申赎行为对投资者收益差距,即基金名义收益率与投资者实际收益率之差的影响。研究发现:(1)基金投资者频繁申赎是导致投资者收益差距的重要因素。(2)过度自信、短视和博彩偏好等行为偏差,促使投资者频繁进行择时交易,增加了择时损失和交易成本,产生了投资者收益差距。(3)在规模较大、普通股票型、男性基金经理管理和个人投资者占比较高的基金样本中,投资者申赎行为对其收益差距的影响更显著。本文为深入理解“基金赚钱、基民不赚钱”的形成机理,推动公募基金市场高质量发展提供了启示。

     

    Abstract: China's actively managed public mutual funds have achieved relatively good returns, yet the anomaly of "funds make money, but fund investors do not" frequently occurs. From the perspective of investor behavioral biases, this paper selects open-end actively managed equity funds as samples to empirically examine the impact of fund investors' subscription and redemption behaviors on the investor return gap, i.e., the difference between funds' nominal returns and investors' actual returns. The findings show that: (1) Frequent subscription and redemption by fund investors is a significant factor contributing to the investor return gap. (2) Behavioral biases such as overconfidence, myopia, and lottery preferences drive investors to engage in frequent market timing trades, increasing timing losses and transaction costs, thereby generating the investor return gap. (3) The impact of investor subscription and redemption behavior on the return gap is more significant in fund samples with larger assets under management, general equity funds, funds managed by male fund managers, and funds with higher proportions of individual investors. This paper provides insights for deeply understanding the formation mechanism of "funds make money, but fund investors do not" and promoting high-quality development of the public fund market.
