Abstract: Portfolio selection (optimization) is an important problem in the area of economy, management and finance. Portfolio includes various financial securities, such as bonds and stocks owned by an organization or by individual. Portfolio optimization is the process of choosing the proportions (weights) of various assets to be held in the portfolio, according to some optimization criteria and constraints. The optimization criteria mix together, directly or indirectly, considerations of the expected value of the portfolio’s rate of return and the return’s dispersion and possibly other measures of financial risk. Portfolio selection problem is a multi-criteria optimization problem where the goal is to minimize risks, while maximizing returns. With the inclusion of additional real-world constraints (such as the transaction costs, constraints arising from the legal environment, the finite divisibility of the assets etc.), the problem becomes much harder. In that case, traditional deterministic methods cannot cope with the computational complexity of the problem and the use of nondeterministic optimization metaheuristics is more promising. Swarm intelligence is a relatively new branch of nature inspired algorithms that very successfully finds suboptimal solutions to hard optimization problems by simulating collective intelligence of swarms of very simple agents like bees, ants, fireflies etc. This plenary lecture presents some successful applications of various swarm intelligence algorithms to portfolio selection problems with different constraint sets.
