The selection of investment portfolios is a complex problem, encompassing multiple and conflicting criteria. We propose an integrated multi-criteria decision-making (MCDM) model composed of the Criteria Importance Through Intercriteria Correlation (CRITIC) method and Grey Relational Analysis...

Cet article se propose d’étudier l’influence de l’âge sur la composition des patrimoines, notamment sur la détention d’actifs risqués. En effet, une hypothèse souvent avancée est que, plus l’horizon de vie se raccourcit, plus la détention d’actifs risqués devrait se réduire....

We propose a new multivariate order based on a concept that we will call extremality". Given a unit vector, the extremality allows to measure the "farness" of a point with respect to a data cloud or to a distribution in the vector direction. We establish the most relevant properties of this...

We investigate a robust version of the portfolio selection problem under a risk measure based on the lower-partial moment (LPM), where uncertainty exists in the underlying distribution. We demonstrate that the problem formulations for robust portfolio selection based on the worst-case LPMs of...

This paper analyses whether Z-score, as examined by Altman and other researchers, can predict correctly company failures. The empirical analysis concentrates on the construction companies listed in Athens Exchange, for the period 1995-2006, which coincides with significant construction activity...

Filtering and parameter estimation techniques from hidden Markov Models are applied to a discrete time asset allocation problem. For the commonly used mean-variance utility explicit optimal strategies are obtained.

This paper presents a new possibilistic programming approach to the portfolio selection problem. It is based on two issues: the approximation of the rates of return on securities by means of fuzzy numbers of trapezoidal form, for which we use the interval-valued ex-pectation defined by Dubois...

We provide a Matlab quadratic optimization tool based on Markowitz's citical line algorithm that significantly outperforms standard software packages and a recently developed operations research algorithm. As an illustration: For a 2000 asset universe our method needs less than a second to...
