This study explores the use of artificial intelligence in stock market prediction. Recent studies have reported that artificial intelligence outperforms traditional techniques when it comes to accuracy performance in forecasting. In this paper, the researchers only focused on the two most known models of artificial intelligence, which are artificial neural network (ANN) and support vector machine (SVM). These models were trained on the 8 indices of the Philippine Stock Exchange, namely, PSEi, all shares, financials, industrial, holding firms, services, mining and oil, and property. Technical and macroeconomic variables from years 2010 to the first quarter of 2016 were used as inputs. The researchers examined and compared the performance of ANN and SVM in forecasting stock price and direction movement. By using paired T-test, RMSE/MAE/MAE and hit miss test in forecasting the value of the 8 indices, it was found that both model can forecast, however, ANN performs better than SVM. Direction symmetry test, on the other hand, showed that ANN and SVM have low accuracy performance in forecasting the direction of the indices. This research will be of great use to market participants who seek new methods in forecasting the Philippine stock market.
