using multi-objective algorithm (nsga-ii) in selecting optimal portfolio in tehran stock exchange
Authors
abstract
in financial matters, portfolio can be interpreted as a combination or a series of investments hold by an institution or a person. portfolio optimization is one of the most important concerns of investors for maximizing the portfolio in financial markets. the formation of portfolio is a vital and critical decision for the companies. in fact, the selection of portfolio is to specify the capital between different shares. so, selecting a portfolio by high returns rate and controlled risk is a matter noted by many researchers. the present ways of optimization the portfolio have not sufficient adequacy. therefore, so many innovative algorithms are considered and used. genetic algorithm can solve many optimization problems of portfolio efficiently. the aim of this research is to completely explain genetic algorithm when using it to optimize portfolio matters. the researcher tries to develop an approach based on a multi-objective algorithm known as nsga-ii to form a portfolio. 30 superior companies listed in tehran stock exchange are selected as the population and their data are used during 2007-2011. the results indicate that genetic algorithm designed is an efficient and appropriate means to help the investors to select a portfolio

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...

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 ...

In this paper, a procedure has been introduced to the multi-objective optimal design of semi-active tuned mass dampers (SATMDs) with variable stiffness for nonlinear structures considering soil-structure interaction under multiple earthquakes. Three bi-objective optimization problems have been defined by considering the mean of maximum inter-story drift as safety criterion of structural compone...

Bone drilling process is one the most common processes in orthopedic surgeries and bone breakages treatment. It is also very frequent in dentistry and bone sampling operations. Bone is a complex material and the machining process itself is sensitive so bone drilling is one of the most important, common and sensitive processes in Biomedical Engineering field. Orthopedic surgeries can be improved...
