Initial public offerings: evidence from the UK

Abstract

This investigation into the performance of Initial Public Offerings on the new Alternative Investment Market reveals that the expected high level of underpricing, that is usually associated with the risky nature of small, young and growing companies, is not supported by the evidence in this study. Raw and market adjusted figures reveal that IPOs listed on AIM at the London Stock Exchange appear to be only conservatively mispriced when contrasted to main board IPO listings in the US, UK and other countries. Due diligence listing requirements could be offsetting the otherwise risky nature of these small, young and growing companies. Finally AIM is discussed in terms of meeting its own targets and its ability to attract international listings.
