Marknadens talan : En eventstudie om marknadens reaktion när företag byter VD

Sammanfattning: Purpose: The purpose of this work is to investigate how the market reacts to a change of CEO and if the impact on the share price is different when a company changes founder-CEO compared to a non founder-CEO. We chose to write about this type of phenomenon mainly because we see that CEOs today are replaced more frequently than before. Theory: The efficient market hypothesis, the agent theory and corporate governance. Method: The study is based on a quantitative deductive research approach. The companies investigated were Swedish companies listed on Nasdaq Stockholm and they have been examined using an event study and two hypothesis tests. Results: The result consists of 20 observations from 20 companies. The cumulated average abnormal return is presented for all days of the event window. The results of the hypothesis tests are also presented. Analysis: The first hypothesis test shows that the announcement of the change of CEO has an impact on the share price. The second hypothesis test shows that there is a difference regarding the impact between the announcement of change of a founder-CEO and a non founder-CEO. The event study shows that the impact of the change of a founder-CEO is positive and the impact of the change of a non founder-CEO is negative. Conclusion: The result of the study shows that the announcement of a change of CEO has a significant impact on the share price and the announcement of the change of a founder-CEO affect the stock price different from the change of a non founder-CEO.
