A factor method for evaluating security returns based on experts¿ judgment is proposed and a mean-chance model for optimal portfolio selection is developed taking transaction costs and investors¿ preference on diversification and investment limitations on certain securities into account. The factor method of evaluation can make good use of experts¿ knowledge on the effects of economic environment and the companies¿ unique characteristics on security returns and incorporate the contemporary relationship of security returns in the portfolio. The use of chance of portfolio return failing to reach the threshold can help investors easily tell their tolerance toward risk and thus facilitate a decision making. To solve the proposed nonlinear programming problem, a genetic algorithm is provided. To illustrate the application of the proposed method, a numerical example is also presented.Related records: En: Insurance : mathematics and economics. - Oxford : Elsevier, 1990- = ISSN 0167-6687. - 03/11/2014 Volumen 59 Número 1 - noviembre 2014 Other categories: 6Rights: In Copyright (InC)Referencias externas:
