Abstract :Heuristic techniques have used frequently in portfolio optimization problem. However, almost none of these techniques used a neural network to allocate the proportion of stocks. The main goal of portfolio optimization problem is minimizing the risk of portfolio while maximizing the expected return of the portfolio. This study tackles a neural network in order to solve the portfolio optimization problem. The data set is the daily price of Istanbul Stock Exchange-30 insert ignore into journalissuearticles values(ISE-30); from May 2015 to May 2017.  This study uses Markowitz’s Mean-Variance model. Indeed, the portfolio optimization model is quadratic programming insert ignore into journalissuearticles values(QP); problem. Therefore, many heuristic methods were used to solve portfolio optimization method such as particle swarm optimization, ant colony optimization etc. In fact, these methods do not satisfy stock markets demands in the financial world. This study proposed a nonlinear neural network to solve the portfolio optimization problem.
