The Cross-Section of Stock Returns Around the World in the Early Twentieth Century
研究了1900至1925年间九国股市，发现动量效应普遍存在，但无长期反转，支持行为金融中反应不足的解释；同时验证了规模效应、低贝塔和低波动股票的优异表现。
Abstract We study nine equity markets between 1900 and 1925 to provide an out-of-sample test of some major asset pricing anomalies during a period in which anomalies had not been documented. We find strong evidence of momentum in almost every market. We find no evidence of long-term reversals, which, coupled with the limited presence of institutional investors, suggests that underreaction should be considered as a key aspect of behavioral theories of momentum. We also find evidence for the size effect, betting-against-beta, and the outperformance of low volatility stocks, whereas we find mixed evidence of short-term reversal.
