In the classical model for portfolio selection the risk is measured by the variance of returns. It is well known that, if returns are not elliptically distributed, this may cause inaccurate investment decisions. To address this issue, several alternative measures of risk have been proposed. In...

In this paper we propose an efficient initialization of a deterministic Particle Swarm Optimization (PSO) scheme. PSO has showed to be promising for solving several unconstrained global optimization problems from real applications, where derivatives are unavailable and the evaluation of the...

In a recent paper, a simple index able to evaluate the non-linear bivariate comovement between two asset prices has been proposed. In this paper we assess if that index satisfies the classical seven axioms formulated by Rényi that a measure of dependence should meet. Further, in the cases in...
