The present study investigates the returns of the shares of six pharmaceutical industries, using the Beta coefficient of the Capital Asset Price Model. First the function and role of stock markets and then their historical development are described, ranging from the Middle Ages to the 21st century, while special reference is given to the evolution of the stock market in Europe. Then an analysis of the pharmaceutical industry is carried out, with reference to its development in the context of herbology and medicine. At this point, historical data of the six pharmaceutical companies in the analysis are presented, with references to pharmaceutical research and development, as well as their collaborations with other companies and their various mergers and acquisitions. In addition, key concepts of portfolio theory are analyzed and the asset valuation model (CAPM) is presented. The study concludes with the empirical analysis of the returns of the pharmaceutical companies’ shares, compared to the returns of the market indices the companies are listed on. The results showed that overall, the listed European pharmaceutical industries in the analysis showed less volatility and risk than stock market indices.
