This paper considers the share price reaction to dividend, earnings, and stock split announcements over a 30 year period. It first considers whether there is differential information content in similar corporate news announcements for different types of firms. Second, it investigates whether the value of news information about these firms has declined over time (has become “less newsworthy”). We categorize firms into groups by whether corporate news announcements regarding the firms will be more valuable to the public. For example, since the public may know more about larger firms, we expect the market to react less strongly (in absolute value) to new information from large firms. We find strong support for this idea. We find little evidence that is consistent with the idea that “news is less newsworthy” over the past few decades. Although, we do find that the share price reaction to “good” dividend news has become less positive and to “bad” dividend news has become less negative over time, no such related evidence exists for stock splits and earnings announcements. Additional investigation of entire distributions of returns using kernel density estimators also rejects the “news is no longer newsworthy” idea.
