【Abstract】 This paper develops a portfolio model to maximize the probability that the rate of return is no less than an expected rate of return. This paper also presents a comparative analysis between traditional models and this model, and explains its realistic meaning. Under the condition that short selling is permitted, this paper presents a method for determining the explicit representation of the optimal portfolio and the criterion function, and gives an illustrative example.更多还原
