ABSTRACT
This paper explores the Support Vector Machine and Least Square Support Vector Machine models in stock forecasting. Three prevailing forecasting techniques - General Autoregressive Conditional Heteroskedasticity (GARCH), Support Vector Regression (SVR) and Least Square Support Vector Machine (LSSVM) are combined with the wavelet kernel to form three novel algorithms Wavelet-based GARCH (WL_GARCH), Wavelet-based SVR (WL_SVR) and Wavelet-based Least Square Support Vector Machine (WL_LSSVM) to solve the non-linear and non-parametric financial time series problem. This paper presents a platform for comparison of the wavelet-based algorithm using Hang Sang Index, Dow Jones and Shanghai Composite Index which has significant influence to each other. It has been discovered that wavelet-based model is not as good as the LS-SVM model. The best result is from LS-SVM without wavelet-based kernel.
