Determining the Optimal Stock Portfolio in Tehran Stock Exchange Based on Multi- Objective Evolutionary Algorithm with Error Level ( -MOEA)

چکیده
Classical statistical models can solve the problem of portfolio optimization and can determine the efficient frontier of investment when there are few investable assets and constraints. But these models cannot easily solve optimization problems when we consider real-world constraints. Therefore, data mining techniques such as evolutionary algorithms are important in portfolio optimization. The purpose of the present research was to solve the meanvariance cardinality constrained portfolio optimization (MVCCPO) problem using -MOEA. Thus, optimal portfolios were created using the monthly returns data of 185 companies listed in Tehran Stock Exchange (TSE) during the period 20092010 and the performance of these companies were evaluated. The results showed that -erorr multi-objective evolutionary algorithm ( -MOEA) can successfully solve the optimization problem.

Using Genetic Algorithm in Solving Stochastic Programming for Multi-Objective Portfolio Selection in Tehran Stock Exchange
Investor decision making has always been affected by two factors: risk and returns. Considering risk, the investor expects an acceptable return on the investment decision horizon. Accordingly, defining goals and constraints for each investor can have unique prioritization. This paper develops several approaches to multi criteria portfolio optimization. The maximization of stock returns, the pow...

متن کاملAn Improved Hybrid Model with Automated Lag Selection to Forecast Stock Market
Objective: In general, financial time series such as stock indexes have nonlinear, mutable and noisy behavior. Structural and statistical models and machine learning-based models are often unable to accurately predict series with such a behavior. Accordingly, the aim of the present study is to present a new hybrid model using the advantages of the GMDH method and Non-dominated Sorting Genetic A...
