According to recent developments of predicting methods<br />in financial markets, and since the stock price is one of the most<br />important factors for investment decision-making, and its prediction<br />can play an important role in this field, the aim of this study is to<br />provide a model to predict the stock price movement with high<br />accuracy. Accordingly, a hybrid model for predicting the stock price<br />movement using Support Vector Machine (SVM) based on genetic<br />algorithms is presented. Thirty companies from the top 50 companies<br />in Tehran Stock Exchange in 2011 are selected as sample. Then, for<br />each company, 44 variables have been calculated. These variables are<br />the inputs of the hybrid model and are optimized using genetic<br />algorithm. The results show that the hybrid model of Support Vector<br />Machine based on genetic algorithms has better performance in<br />predicting the stock price movement and it has a higher accuracy<br />compared with the simple Support Vector Machine.
