Corporate Takeovers in Sweden : The effect on bidder´s shareholder return

by Mandell, Mikael

The purpose of this master’s thesis is to examine the effect a corporate takeover an-nouncement has on share prices for acquiring companies. The test will only involve com-panies listed on the Stockholm Stock Exchange during the period 1996 to 2005. To test the effect an announcement has, abnormal return for a period before and after the takeover announcement was calculated. The findings from the testing showed that takeover an-nouncements have a significantly impact on shareholder return. The majority of acquirers in the sample had negative average abnormal returns during the event period (100 days prior to the announcement and 100 day after).
