This paper proposed the optimal portfolio model maximizing returns and minimizing the risk expressed as CvaR under the assumption that the portfolio return subjects to heavy tail. With linear weighted sum method, we solved the multi-objectives model, and compared the model results to the case under the assumption of normal distribution portfolio return,… (More)
