This paper explores the performance of a global minimum variance (GMV) portfolio in dependence of the structure of the covariance matrix and the type of volatility model.

This study investigates the effects of dividend announcements on stock prices and trading volume in the Austrian stock market. Abnormal returns are established as the difference between actual returns and expected returns generated by the Market Model. We use the model of expected dividends such...

For plain vanilla options the martingale pricing formulae are usually expressed in terms of artificial probabilities using different numeraires. Firstly, this allows fuuml;r a concise and intuitive representation of the pricing equation. Secondly, it is of major importance for computational...

It is a common belief, especially among financial industry professionals, that hectic periods in financial markets are accompanied by modifications in the risk factors dependence structure. We consider correlation as a proxy fuuml;r measuring dependence and use for empirical study representative...

Estimation of the covariance matrix is an essential task of portfolio selection. A multivariate approach is needed. Unfortunately, it is leading to a flat likelihood function for a realistic number of assets. This paper is proposing a principal components analysis together with a sophisticated...

The study analyses the characteristics of professional exchange rate forecasts for the /US-$ rate. The results indicate that the quality of forecasts produced by professional economists is rather poor and incompatible with the rational expectations hypothesis. This dismal result is according to...
