| Abstract: | The patterns of daily returns in over-the-counter (OTC) stocks are examined to determine if a holiday effect exists in the OTC market. For the sample period of 1973–1989, test results provide evidence of unusually high returns on pre-holiday trading days and unusually low returns on post-holiday trading days in the OTC market. Additional analyses indicate that other documented calendar anomalies do not cause the pre-holiday effect, but the day-of-the-week effect apparently drives the post-holiday effect. |
