Therefore, in this research, to present a multi-objective mathematical model for measuring stock portfolio risk by combining return metrics with two risk metrics, namely half variance and conditional risk exposure value along with transaction cost limit for fifteen shares of the top fifty stocks. The period of twelve months ending in 1398 has been discussed in the context of the Iranian capital market. According to the tables and graphs obtained from solving this type of model with the help of dynamic planning in different investment times, we will see better results in the efficiency of investors' decisions by spending less time and money and consequently more profitability of the portfolio.
