我们研究美国行业投资组合的回报是否可以预测 Fama 和 French 的小减大 (SMB) 和高减低 (HML) 因子的回报和波动性。分析显示,所有 30 个行业的回报都强烈预测了未来一个月的中小企业因子回报。此外,大量行业回报预测 SMB 和 HML 因子的波动性可达两三个月。这些发现表明,美国行业回报包含Fama-French SMB和HML因子的盈利信息,由于大多数投资者无法及时提取行业回报中包含的盈利信息,因此这些信息逐渐在股票市场中扩散。
We examine whether the returns of US industry portfolios predict the returns and volatility of Fama and French's small-minus-big (SMB) and high-minus-low (HML) factors. The analysis reveals that all 30 industry returns strongly forecast one-month-ahead SMB factor returns. Moreover, a significant number of industry returns predict the volatility of the SMB and HML factors by up to two or three months. These findings suggest that US industry returns contain profitable information on Fama–French SMB and HML factors, and since most investors cannot extract the profitable information contained in industry returns in a timely manner, this information gradually diffuses in equity markets.
