Behzad Safaei Management Dept., Faculty of Economics and Management, University of Shiraz, Shiraz, Iran Hamed Saberi Management Dept., Faculty of Economics and Management, University of Shiraz, Shiraz, Iran Journal Article 2014 05 04 This study is based on Mousavi and Setoudeh (2013) that simulates stock price behavior of national Iranian copper industrial companies in Iran stock exchange. This paper provides the possibility of analyzing stock price fluctuations and forecasting intrinsic stock price from internal and external viewpoints. For modeling stock behavior, some internal and external factors are identified and the relation between different variables is shown by causal diagrams using system dynamics approach. The financial variables are considered in three groups of pricing, price, and debt financing. Research model is simulated and analyzed by this approach and by using the Vensim DSS software. The overall results indicate that stock supply has important effect on stock price, and debt financing has positive impact on stock’s intrinsic value. <br />  This study is based on Mousavi and Setoudeh (2013) that simulates stock price behavior of national Iranian copper industrial companies in Iran stock exchange.
