内容摘要:
Characteristics of one firm may contain value-relevant information for a set of economically related peer firms. This paper employs a flexible machine-learning approach to aggregate information from a large number of peer characteristics, as well as deviations of firms' own characteristics from the peer averages, into two aggregate peer-based indices: the Peer Index (PI) and the Peer Deviation Index (PDI). The two indices reliably predict future returns, even after controlling for a comprehensive list of other anomaly variables, as well as adjusting for data-snooping bias and microcaps. Individually, long-short value-weighted portfolios based on PI and PDI each generate monthly excess returns of 1.5% and 2.2%, respectively, with Sharpe ratios of 1.15 and 2.28. Combining the two signals, a long-short double-sorted portfolio generates monthly excess returns of 3.48% (with a Sharpe ratio of 2.52). We present evidence that the predictability of PI and PDI arises from the gradual diffusion of information and anchoring to peer fundamentals, respectively.
