%X This paper considers a minimax model for optimal portfolio selection at the situation that the return rates of risky assets can not be precisely estimated. The authors introduce transaction costs into the minimax model and the transaction cost is taken as a V-shaped function of the difference between the existing portfolio and a new one. For independent capital assets, the authors derive the analytical expression of an optimal portfolio with no-short sales.
