| Abstract: | This paper studies the day-of-the-week effect employing Canadian stock returns from January 1, 1975 to June 30, 1989. The study finds that, as opposed to large capitalization stocks, low capitalization (thinly-traded) stocks tend to have a larger negative return on Tuesday rather than on Monday - possibly due to lags in the price adjustment of these stocks following the release of negative information. Two main issues are investigated in an attempt to explain the day-of-the-week effect and its persistence over time: (a) the role of dividends, and (b) the role of information flows. The study finds that firms are much more likely to go ex-dividend on Monday than on any other day of the week; however, after correcting for the dividend effect, Monday's returns are still significantly negative. With respect to information flows, we find evidence consistent with an information-flows-related explanation of the day-of-the-week effect, particularly with the idea that macro announcements cause negative Monday returns. |
