We consider the problem of investment and consumption with a hidden Markov model and a regime switching structure. The Bayesian approach is followed to integrate econometric consideration and to make inference of the hidden Markov model. The optimal investment strategy is characterized by the method of stochastic dynamic programming and simulation results are given.

As we know, the performance of the mean–variance approach depends on the accurate forecast of the return rate. However, the conventional method (e.g. arithmetic mean or regression-based method) usually cannot obtain a satisfied solution especially under the small sample situation. In this paper, the proposed method which incorporates the grey and possibilistic regression models formulates the n...

Portfolio selection represents a challenge where investors look for the best firms of the market to be selected. This research presents a real world application at the Mexican Stock Exchange (La Bolsa) using a set of heuristic algorithms for portfolio selection. The heuristic algorithms (random, genetic, greedy, hill-climbing and simulated annealing) were implemented based on the Markowitz Mode...
