<field name="value">In this study, a model for the selection of investment portfolios is proposed with three objectives. In addition to the traditional&#xd;
objectives of maximizing profitability and minimizing risk, maximization of social responsibility is also considered. Moreover,&#xd;
with the purpose of controlling transaction costs, a limit is placed on the number of assets for selection. To the best of our&#xd;
knowledge, this specific model has not been considered in the literature to date. This model is difficult (NP-Hard), and therefore,&#xd;
only very small instances may be solved in an exact way. This paper proposes a method based on tabu search and multiobjective&#xd;
adaptive memory programming (MOAMP) strategies. With this method it is possible to obtain sets of nondominated solutions in&#xd;
short computational times. To check the performance of our method it is compared with adaptations of the nondominated sorting&#xd;
genetic algorithm (NSGA-II), strength Pareto evolutionary algorithm (SPEA-II) and multiobjective particle swarm optimization&#xd;
(MOPSO). The results of different computational experiments show that our tabu search-MOAMP method performed best. The&#xd;
quality of the sets of solutions that were obtained and the speed of execution mean that our tabu search-MOAMP can be used as a&#xd;
tool for financial assessment and analysis (including online services). This tool, as we can see in this work with some examples,&#xd;
can take into account the social concerns of many clients and their overall risk profile (very conservative, conservative, moderate,&#xd;
or fearless). This approach is also in line with current legal regulations that oblige financial advisors to take the client profile into&#xd;
account to provide greater protection and propose good financial advice.</field>
