Academic Knowledge Dissemination in the MutualFund Industry: Can Mutual Funds Successfully Adopt FactorInvesting Strategies?
研究了1990至2010年间美国股票型共同基金采用基于学术文献中资产定价异象的投资策略能否获得超额收益，发现低贝塔、小盘和价值基金能持续获得显著超额收益，且这些收益在异象公开后并未消失。
The authors investigate whether investors who have adopted investment strategies based on asset pricing anomalies documented in the academic literature consistently earn abnormal returns. They evaluate the performance of a large sample of U.S. equity mutual funds over the period from 1990 to 2010. They find evidence supporting added value for investors who adopt factor-investing strategies: low-beta, small-cap and value funds earn significant excess returns. They also find that these excess returns are sustainable and have not disappeared after the public dissemination of the anomalies. The authors propose some criteria that might be helpful to determine the successful application of academic insights in the context of investment strategies. Their findings have significant implications for the role of academic research and knowledge management in the investment management industry. <b>TOPICS:</b>Mutual fund performance, statistical methods, financial crises and financial market history
