<p>The goal of this study is to examine how the market reacts when information about the exchange of a CEO becomes public. It also examines factors such as gender and whether the departure was voluntary or not, discerning if the market behaves differently concerning any of these aspects.To achieve this, the study was performed using an event study. The selection consisted of 48 companies on the Stockholm Stock Exchange, who had during the years 2005 to 2008 underwent a change in leading management. These units were submitted to hypothesis tests, to determine if an abnormal return was attained during the event window. The tests were performed on the units as a whole, and divided up after gender and whether the departure was voluntary or not.The results of the study show no statistically significant abnormal return caused by the announcement of a CEO exchange. There were however some indications of a deviation when the units were divided between voluntary and involuntary departure, though not strong enough to be considered significant. Not even when the days of the event window were divided and examined separately, did the results show any significant reaction. This can be an indication that the semi‐strong version of the Efficient Market Hypothesis is not at work.</p>
