| Abstract: | Semi-strong efficiency in the stock market implies that all public announcements like changes in annual earnings, declared cash dividend, firm management are fully reflected in security prices. The testing of how fast stock prices adjust to specific kinds of new information is usually based on statistical analysis of residuals derived from Sharpe's model. In most cases the result of these analyses is that during periods without crash the semi-strong form efficiency hypothesis is supported. The prime concern is to examine how the Belgian stock prices adjusted to the announcement of increased cash dividend and/or earnings in October 1987. |
