Dissecting Anomalies
发现净股票发行、应计项目和动量带来的异常收益普遍存在于各类规模股票中，而资产增长和盈利能力的异常则较弱，仅在小盘股中显著。
ABSTRACT The anomalous returns associated with net stock issues, accruals, and momentum are pervasive; they show up in all size groups (micro, small, and big) in cross‐section regressions, and they are also strong in sorts, at least in the extremes. The asset growth and profitability anomalies are less robust. There is an asset growth anomaly in average returns on microcaps and small stocks, but it is absent for big stocks. Among profitable firms, higher profitability tends to be associated with abnormally high returns, but there is little evidence that unprofitable firms have unusually low returns.
