Portfolio selection with limited downside risk

چکیده
A safety-first investor maximizes expected return subject to a downside risk constraint. w Arzac and Bawa Arzac, E.R., Bawa, V.S., 1977. Portfolio choice and equilibrium in capital x markets with safety-first investors. Journal of Financial Economics 4, 277–288. use the Value at Risk as the downside risk measure. The paper by Gourieroux, Laurent and Scaillet estimates the optimal safety-first portfolio by a kernel-based method, we exploit the fact that returns are fat-tailed, and propose a semi-parametric method for modeling tail events. We also analyze a portfolio containing the two stocks used by Gourieroux et al. and discuss the merits of the safety-first approach. q 2000 Elsevier Science B.V. All rights reserved.

Developing a multi objective possibilistic programming model for portfolio selection problem
Portfolio selection problem is one of the most important issues in the area of financial management in which is attempted to allocate wealth to different assets with controlling the return and risk. The aim of this paper is to obtain the optimum portfolio with regard to the cardinality and threshold constraints. In the paper, a novel multi-objective possibilistic programming model is developed ...
متن کاملFuzzy portfolio optimization under downside risk measures
This paper presents two fuzzy portfolio selection models where the objective is to minimize the downside risk constrained so that a given expected return should be achieved. We assume that the rates of returns on securities are approximated as LR-fuzzy numbers of the same shape, and that the expected return and risk are evaluated by interval-valued means. We establish the relationship between t...
متن کاملRobust tracking error portfolio selection with worst-case downside risk measures
This paper proposes downside risk measure models in portfolio selection that captures uncertainties both in distribution and in parameters. The worst-case distribution with given information on the mean value and the covariance matrix is used, together with ellipsoidal and polytopic uncertainty sets, to build-up this type of downside risk model. As an application of the models, the tracking err...
متن کاملRobust Utility Maximization with Limited Downside Risk in Incomplete Markets
In this article we consider the portfolio selection problem of an agent with robust preferences in the sense of Gilboa & Schmeidler (1989) in an incomplete market. Downside risk is constrained by a robust version of utility-based shortfall risk. We derive an explicit representation of the optimal terminal wealth in terms of certain worst case measures which can be characterized as minimizers of...
متن کاملPortfolio Selection Models: a Review and New Directions
Modern Portfolio Theory (MPT) is based upon the classical Markowitz model which uses variance as a risk measure. A generalisation of this approach leads to mean-risk models, in which a return distribution is characterised by the expected value of return (desired to be large) and a ”risk” value (desired to be kept small). Portfolio choice is made by solving an optimisation problem, in which the ...
