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...

We analyse the performance of simple investment strategies in IPOs based on a large sample of IPOs in Germany between 1985 and 2002. In particular, we compare the performance of the following strategies: Invest equally weighted in each IPO, invest market value weighted in each IPO, invest in an...

The concept of utility is the core component of many foundational theories in social sciences. It has evolved from a philosophical belief that people seek happiness and satisfaction to a mathematically derived theory in economics and finance. Beginning with a brief review of the developments in...

In this paper we analyze the consistency of financial investment ordering based on mean-variance and stochastic dominance (SD) approaches in the context of an emerging financial market. We take 47 Chilean mutual funds and compute Sharpe index and the algorithms to verify first (FSD), second...

This study proposes a method to enhance cryptocurrency portfolios constructed by forecast models. This study forecasts returns on four liquid cryptocurrencies (Bitcoin, Litecoin, Ripple, and Dash) and determines the weights on the cryptocurrencies based upon a dynamic allocation framework. We...

Disputes whether financial structure can create value or not were started more than 50 years ago with Modigliani Miller theorem. In this paper I would like to present my own view on level of debt in value creation process. What I am going to prove is that due to expansion option companies with...

An anchoring adjusted Capital Asset Pricing Model (ACAPM) is developed in which the payoff volatilities of well-established stocks are used as starting points that are adjusted to form volatility judgments about other stocks. Anchoring heuristic implies that such adjustments are typically...
