Medföljer avkastning till följd av börsintroduktion? : En eventstudie om börsintroduktioner och dess kortsiktiga avkastning på Stockholmsbörsen

Sammanfattning: Background: Underpricing is the most studied area in the subject of IPO. The phenomenon is mainly described as a compensation for the risk of investing in a newly introduced company. Underpricing of shares is explained for many reasons, but the main reason is assumed to be the presence of asymmetric information on the market. Due to differences in financial systems between different countries, creates an incentive to conduct this study on the swedish market. Purpose: The purpose with this essay is to study the short term profitability of IPOs on the swedish market Method: The study is based on a quantitative research design with a deductive approach. The main method is the well established Event Study Method used by MacKinlay (1997), to measure the abnormal return of initial public offerings from the first-day return up to the following month’s return. Research has included 179 publicly traded incorporated companies on the swedish market between the years 2010 to 2020. Conclusion: The authors concluded, through analysis of the empirical basis with relation to previous studies and theories, drawn their own conclusions. Initial public offerings historically show higher returns compared to the market index. The study shows an abnormal first-day return of 0,4490%. Based on an analysis of the empirical results, it was found that the results were consistent and corresponds with previous research in the field of IPOs in other markets. In addition, the selected variables, namely the initial return of 9,21% as a result of IPOs, could partially interpret the abnormal first-day return as well as the following week’s and month’s. The other variables did not appear to be of statistical significance during any of the study periods.
