Private investors increasingly use passive investment strategies, i.e. investment methods that try to replicate a stock market index as accurate as possible. In this paper we compare retail index certificates and exchange traded funds. Both investment products promise a performance that...

This paper discusses the role of the credit rating agencies during the recent financial crises. In particular, it examines whether the agencies can add to the dynamics of emerging market crises. Academics and investors often argue that sovereign credit ratings are responsible for pronounced...

The use of GARCH models with stable Paretian innovations in financial modeling has been recently suggested in the literature. This class of processes is attractive because it allows for conditional skewness and leptokurtosis of financial returns without ruling out normality. This contribution...

In this paper, we develop modeling tools to forecast Value-at-Risk and volatility with investment horizons of less than one day. We quantify the market risk based on the study at a 30-min time horizon using modified GARCH models. The evaluation of intraday market risk can be useful to market...

The goal of this study is to estimate the impact of cross-listing on stock returns, on liquidity, and on risk. A sample of 24 companies from the Gulf Cooperation Council countries which cross-listed their stocks in a foreign market over the period 2000–2010 were chosen for study. An event...

Risk management has attracted a great deal of attention, and Value at Risk (VaR) has emerged as a particularly popular and important measure for detecting the market risk of financial assets. The quantile regression method can generate VaR estimates without distributional assumptions; however,...

Portfolio optimization problems involving value at risk (VaR) are often computationally intractable and require complete information about the return distribution of the portfolio constituents, which is rarely available in practice. These difficulties are compounded when the portfolio contains...

This paper proposes a robust multivariate threshold vector autoregressive model with generalized autoregressive conditional heteroskedasticities and dynamic conditional correlations to describe conditional mean, volatility and correlation asymmetries in financial markets. In addition, the...

Teniendo en cuenta el nuevo esquema de multifondos en Colombia, perteneciente al Régimen de Ahorro Individual, se realizó un análisis mediante la aplicación de herramientas estocásticas y actuariales, con el fin de determinar el momento en el cual un agente (de acuerdo con sus...
