Identification of Asset Price Misalignments on Financial Markets With Extreme Value Theory

ABSTRACT This article examines the potential for concurrence of crises and asset price misalignments from equilibrium in the foreign exchange, stock, and government bond markets of three Central European countries and the euro area. Concurrence is understood as the joint occurrence of extreme asset changes and is assessed with a measure of asymptotic tail dependence in the distributions studied. The results reveal a significant potential for the co-alignment of crises in the examined markets. Evidence for co-movements in misalignments from equilibrium is found among all examined stock and exchange rate markets; although it is not apparent in some government bond markets.

Predikce využívající experimentální trhy

According to the effective market theory, the stock prize on an effective market is the best estimate of the stocks current value. This is the basic assumption for predictions using experimental markets. This article describes the first experimental market organised in the Czech Republic, the experimental political market for Czech parliamentary elections in June 2002. In the beginning we briefly describe the methodology of the predictions via electronic markets. Than we give some description of our market- number of traders, their individual results, development of the market activity in time, etc. Finally we compare the result of our election market with the traditional opinion polls. On the basis of his comparison we discuss the advantages and the limitations of the prediction using the experimental markets.
