The aim of the current research is to model the enhanced index tracking portfolio using polynomial goal programming and based on the index fund considerations. This research uses a goal programming model for index tracking, which is solved using both PSO methods (implemented in MATLAB) and exact methods through GAMS for Tehran Stock Exchange Funds. This study evaluates the performance of investment portfolios constructed through particle swarm optimization (PSO), exact solution using GAMS, and various fund benchmark indices. Studies have been conducted based on the characteristics of 5 index funds of the country and using data from 2012 to 2023. Although each method shows unique strengths, no significant difference has been observed in the daily returns of the three portfolios obtained from the three methods over the entire time period, which reveals good index tracking performance of PSO and GAMS. Meanwhile, PSO has shown the potential for higher returns under certain conditions, indicating its suitability for risk-tolerant investors seeking higher returns.
