Modelo Multiobjetivo para Seleção de Portfólios com Restrição de Cardinalidade, Custo de Transação e Valor em Risco Condicional

Abstract: Recebido em 13 abril, 2016 / Aceito em 6 novembro, 2016 RESUMO. Este trabalho apresenta um modelo multiobjetivo para seleção de portfólios de ações do mercado financeiro, que leva em consideração a restrição de cardinalidade, os custos de transação e os limites de investimento para cada ativo e para grupos de ativos. As funções-objetivo consideram o valor em risco condicional (CVAR -Conditional Value-at-Risk ) como medida de risco e o valor esperado dos retornos históricos ponderados pelas proporções de invest… Show more

“…One of the restrictions, addressed by the portfolio selection problem, is the cardinality constraint, which limits the value of assets in a portfolio, classifying the problem as NP-Hard. The portfolio problem is in the class of combinatorial optimization problems and exact methods cannot find optimal solutions in polynomial time, according to [8]. All of these factors motivate the use of a multi-objective meta-heuristic algorithm to optimize the problem and obtain solutions close to the optimal solution.…”
