Who knows what when? : The information content of pre-IPO market prices : [Version March/June 2002]
(2002)
To resolve the IPO underpricing puzzle it is essential to analyze who knows what when during the issuing process. In Germany, broker-dealers make a market in IPOs during the subscription period. We examine these pre-issue prices and find that they are highly informative. They are closer to the first price subsequently established on the exchange than both the midpoint of the bookbuilding range and the offer price. The pre-issue prices explain a large part of the underpricing left unexplained by other variables. The results imply that information asymmetries are much lower than the observed variance of underpricing suggests.
Deutsche Börse AG plans to introduce a system (Xetra Best) allowing brokers and broker-dealers to internalize the orders of retail customers. Further, Xetra Best supports payment for order flow arrangements. Both internalization and payment for order flow may be detrimental to market quality. This paper discusses advantages and disadvantages of these arrangements. It draws on experiences made in the US. We derive policy implications that aim at a more stringent interpretation of "best execution", and at higher transparency. Klassifikation: G10, G14
