This paper illustrates an application of wavelets as a possible method for prediction of financial data. One of the benefits of a wavelet approach is the flexibility in handling very irregular data series. In this study intended to use wavelet transform to do pre-processing on the finance time series data. The entire procedure can be roughly divided into three steps: wavelet decomposition, signal extension and wavelet reconstruction. The predicted results are compared with output from time series regression model. The most important property of wavelets for economic analysis is decomposition by time scale. Economic and financial systems, like many other systems, contain variables that operate on a variety of time scales simultaneously so that the relationships between variables may well differ across time scales.
