<meaning-changed>  The Straits Times Index, Nikkei 225, NASDAQ Composite, S P 500, and Dow Jones Industrial Average indices were utilized as time series data sets for training and testing proposed predic-tive model.
 The Straits Times Index, Nikkei 225, NASDAQ Composite, S prediction model. Furthermore, the study also presents a comparative performance evaluation of three different stock price forecasting models; namely, the particle swarm optimization trained feedforward neural network model, the genetic algorithm trained feedforward neural network model and the well-known ARIMA model. The system developed in support of this study utilizes sixteen stock indices as time series data sets for training and testing proposed predic-tive model.
