The underpricing phenomenon of Initial Public Offerings (IPOs) has been widely studied across different stock markets around the world and has often been explained to be as a result of asymmetrically distributed information and ex-ante uncertainty. However, as Ritter and Welch (2002) argue to...

The overallotment or greenshoe option has become very popular in the German IPO market since its introduction in 1995 and is nowadays an important tool to stabilize IPOs or to issue additional shares in the case of excess demand. Besides providing evidence for the prevalence of price support...

A simple manipulation of the cointegrated framework proposed by Lettau and Ludvigson (2001, 2004) allows to demonstrate that temporary fluctuations of the U.S. consumption-wealth ratio predict excess returns on international stock markets. This finding is the reflection of an important common,...

The decomposition of a European market return into cashflow and discount rate news components suggests that returns on European and country value portfolios react more sensitive to news about the European market return´s cashflows than the corresponding growth portfolios. This evidence is...

Proprietors are an important group of stockholders and non-diversifiable entrepreneurial risk could therefore help explain time-varying risk premia on the aggregate stock market. This paper suggests an entrepreneurial distress factor that is highly correlated with the aggregate...

Pragmatic-world nominal riskless rates are non-negative. However, conventional arbitrage theory has yet to develop a theoretical justification of this phenomenon. – We define the null-alternative cash as an investor holding onto cash and refraining from investment and consumption ("doing...

This paper uses an empirical connection between real stock market indices of Germany and the USA for forecasting corresponding returns. We are starting from the random walk as the traditional forecasting model in stock market applications, extending it by co-integration. Since the cointegrating...

Classical single-factor comparable company valuation (CCV) like e.g. valuation using the price-earnings ratio is associated with several shortcomings. The two most important are the non-applicability of negative values in the basis of reference and the high requirements to the qualitative...

This paper presents and compares several time-series models for returns of broadbased stock indices. These models nest a nonlinear asymmetric GARCH (NGARCH) model as a special case. Some of these models are empirically motivated ad-hoc specifications others are derived from a representative...
