Firm Size and the Information Content of Annual Earnings Announcements: Australian Evidence
24 Pages Posted: 6 Feb 2005
We investigate the effect of firm size on the market's short-window response to annual earnings announcements for a large sample of Australian listed companies. Our research design involves regressions of unexpected earnings against unexpected returns. Non-linearity in the returns-earnings relationship is incorporated and other factors known to affect the response to earnings announcements are controlled for. Contrary to prior US research, our results show that firm size has either no effect on the response to earnings announcements (3 day window) or the response is significantly stronger for larger firms (twenty-one day window). The information content of earnings announcements is present across firm size categories but the nature of the response differs with firm size and context.
