  In this paper, we propose a modification to the use of the risk aversion coefficient in optimization models, based on research literature and mathematical methods. The modified risk aversion coefficient introduced in this paper can be applied in the maximization part of the model without any adverse effects. By doing so, it can improve the accuracy of meta-heuristic algorithms in finding optimal solutions. To test the efficacy of our proposed model, we applied it to 30 shares of the Tehran Stock Exchange, along with a zero-risk asset, taking into account some limitations in the market. We used a genetic meta-heuristic optimization method to solve the model, and to measure its efficiency, we compared the results of the optimization process with 2500 randomly generated portfolios that were within the problem's constraints. Our results show that our model outperforms the random portfolios in terms of both risk factors and return. In conclusion, our proposed modification to the risk aversion coefficient can improve the accuracy of optimization models, and our results demonstrate its effectiveness in generating optimal portfolios in the market.

  Capital markets have an important role in the economy, so their proper performance will be a key factor in ensuring economic growth, so if capital markets are efficient, economic development will be realized. On the other hand, since currently the country's capital market has been welcomed by investors, it is undoubtedly very important to examine the behavior patterns of investors. Therefore, in this study, the effect of self-control behavioral bias on financial behavior and financial well-being was investigated through the moderating role of investors' financial literacy. For this purpose, the statistical population included individual investors, traders and brokers of Tehran Stock Exchange who were directly active in the market. Also, the statistical sample was determined using Cochran's formula of 421 people. To analyze the data, the PLS structural equation model was used. The results showed that the self-control variable has a significant positive effect on financial behavior, financial well-being and In the sense that with the increase of self-control of stock market investors, their financial behavior and financial well-being will increase. Also, by introducing the variable of financial literacy as a moderating variable, the intensity of the relationship between self-control and behavior and financial well-being increases. In the sense that the financial literacy of individual stock market investors increases the positive relationship between self-control and their behavior and financial well-being. Manuscript profile
