Do Acquirers Benefit from M&A’s? - : An Event Study on 517 Swedish M&A’s: 1998-2016

We investigate the acquiring firms share value response to M&A’s performed by public acquirers active on the Swedish market in 1998-2016. Our research builds upon previously conducted studies depicting both positive- and negative returns. Furthermore, our study considers how M&A’s are affected by merger waves and their creation of hot and cold markets. Our sample consists of 517 acquisitions including both smaller and larger transactions. Through an event-study, we investigate how the share value reacts during an 11 day event window surrounding the announcement of an M&A.
