Cardinality-constrained Distributionally Robust Portfolio Optimization | DeepAI

Cardinality-constrained Distributionally Robust Portfolio Optimization | DeepAI To exactly solve large scale problems, we propose a specialized cutting plane algorithm that is based on bilevel optimization reformulation. we prove the finite convergence of the algorithm. We develop the cutting plane algorithm for solving the cardinality constrained distributionally robust portfolio optimization problem. we also prove that our algorithm outputs a solution with guaranteed global optimality in a finite number of iterations.

Wasserstein Distributionally Robust Chance Constrained Trajectory Optimization For Mobile Robots ...

Wasserstein Distributionally Robust Chance Constrained Trajectory Optimization For Mobile Robots ... In this section, we formulate the cardinality constrained distributionally robust portfolio optimization model that we consider in this paper as an misdo problem. Using integer programming, the project demonstrates how adding a cardinality constraint transforms a convex markowitz optimization problem into a combinatorial, non convex challenge —motivating the need for advanced solvers and quantum inspired approaches. For a mean cvar model with cardinality constraint, we consider the situation where the true distribution of underlying uncertainty is unknown. we develop a distribution ally robust mean cvar model with cardinality constraint (drmcc) and construct the ambiguity set by moment information. In this paper, we develop a new approach to solve cardinality constrained portfolio optimization problems with different constraints and objectives. in particular, our approach extends both.

M.f. leung, j. wang, "cardinality constrained portfolio selection based on collaborative neurodynamic optimization", neural networks, volume 145, pages 68 79, january 2022. Abstract: this paper studies a distributionally robust portfolio optimization model with a cardinality constraint for limiting the number of invested assets. we formulate this model as a mixed integer semidefinite optimization (misdo) problem by means of the moment based ambiguity set of probability distributions of asset returns. Our strategy balances the trade off among the return, the risk, and the number of assets with cardinality constraints. therefore, we provide a theoretically sound and computationally efficient strategy to make pm practical in the growing global financial market. We propose an end to end distributionally robust system for portfolio construction that integrates the asset return prediction model with a distributionally robust portfolio optimization model. we also show how to learn the risk tolerance parameter and the degree of robustness directly from data.
