Description: This paper is concerned with the evaluation of the common portfolio management strategy which consists of delegating to different managers portions of the assets to be invested. This practice is shown to be close to optimal under the realistic assumption that the private signals of the financial experts are positively correlated. This is accomplished by comparing this multi-manager approach to an optimal investment policy derived under full information, within the context of a standard normal returns/exponential utility market timing model.

Description: The theme of this paper relates to solving portfolio selection problems using linear programming. The authors extend the linear optimization framework for Conditional Value-at-Risk-based portfolio selection problems to optimization over a more general class of risk measure known as the class of Coherent Distortion Risk Measure.
