The book "Capital market reaction to ad hoc publicity: Evidence from Switzerland" offers a comprehensive analysis of the impact of ad hoc publications on the Swiss stock market. Ad hoc publications are mandatory press releases from publicly traded companies that contain price-sensitive information. This study examines a variety of ad hoc announcements made by companies listed on the SIX Swiss Exchange. The author, Yvette Feldmann, analyzes which categories of news have significant effects on stock prices and how market reactions differ. By applying empirical research methods, the relevance of the information is measured through abnormal returns on the announcement day. The results of this investigation provide valuable insights into the dynamics of the Swiss stock market and assist investors and students in identifying critical information variables and understanding financial models in practice.
