Abstract Text | he long-run underperformance of initial public off erings (IPOs) is a well-documented phenomenon. This st udy reviews the theories and provides evidence for up to a three-year aftermarket period from a sample of 67 stoc k issues at the SIX Swiss Exchange between 2000 and 2015. The analysis of the anomaly is based on several alternative approaches. Applying event-time returns, it was found that investors on average realise an abnormal return of up to -26.66%. Calendar-time portfolio returns confirm underperformance. Significance, however, highly depends on the methodology, which counters a distinct IPO effect. Various multiple regression models provide some explanations for the return behaviour. Firm size and the new economy sector exert a negative impact, while firm age and underwriter reputation indicate a positive influence. The outcomes partly support the uncertainty and divergence of opinion hypothesis. |
