We assess the ability of minimum-variance portfolio allocation strategies accounting for time-varying correlation between assets to provide performance benefits relative to an equally-weighted portfolio. Prior to transaction costs correlation-based strategies emphatically outperform the...

Challenges to the empirical implementation of portfolio optimization abound, leading to a recent focus upon the naïve equally weighted portfolio as asset allocation benchmark. In this paper, we extend the performance analysis of the naïve allocation approach to encompass data both within and...

The aim of this paper is to provide a modeling of capital transfer between a portfolio consisted by two assets. For this purpose we use the Arrhenius Equation, which is a modeling tool for the specific modeling. We provide a stochastic differential equation of the Arrhenuis equation. We consider...

We examine the international impact of recent financial crises on contagion dynamics within international equity portfolios. First, we highlight the importance of macroeconomics for portfolio weighting for each region, and then we examine contagion via a structural regime-switching model and a...
