Abstract
Grandville law, which is one of the technical analysis methods, is combined with Wavelet analysis. We have performed evaluation of the effectiveness of the analysis technique for estimating stock prices. The optimal parameters are searched both for Grandville law and Wavelet analysis by simulation for 11 years, applied to 20 descriptions. The obtained parameters are applied to other 30 descriptions in order to evaluate the method. We compared performances by single Granville law, single Wavelet analysis and the combination of these, which is our proposal. The result showed that the combined method is the most excellent in that it can be applied to many descriptions properly, and an average gain was 36%.
