An asymmetric multivariate generalization of the recently proposed class of normal mixture GARCH models is developed. Issues of parametrization and estimation are discussed. Conditions for covariance stationarity and the existence of the fourth moment are derived, and expressions for the dynamic...

We develop a multivariate generalization of the Markov-switching GARCH model introduced by Haas, Mittnik, and Paolella (2004b) and derive its fourth-moment structure. An application to international stock markets illustrates the relevance of accounting for volatility regimes from both a...

The aim of portfolio insurance strategies is to put a floor on the value of a stock portfolio by progressively selling stocks and buy safe, short-term debt securities as stock prices fall. This paper analyzes the current static and dynamic methods in use and explains their pros and cons.

Traditional risk-adjusted performance measures, such as the Sharpe ratio, the Treynor index or Jensen's alpha, based on the mean-variance framework, are widely used to rank mutual funds. However, performance measures that consider risk by taking into account only losses, such as Value-at-Risk...

There is a huge literature on the effects of uncertainty on trade levels. One very strong result of that literature is that uncertainty should not matter, as long as well developed forward markets exist. The empirical implications of this result, however, are hard to find in the data. We model...

In this paper, we examine the reaction of stock market returns and volatility in a diverse group of six emerging markets to a set of IMF events. In particular, we test within a panel framework whether there was an “investor panic” causing a significant drop in stock market returns on the...
