An examination of the behavior of stock returns around quarterly earnings announcement dates finds a seasonal pattern: small firms show large positive abnormal returns and a sizable increase in the variability of returns around these dates.

Large firms show no abnormal returns around announcement dates and a much smaller increase in variability.
