Stock Prices Prediction Based on Granville's LawModified by Wavelet Analysis

摘要

In order to predict the stock price, modified Granville's law based on the Wavelet Analysis wasdeveloped. This method is expected to improve profit of the stock trading. Since the conventionalGranville's law is not suitable to estimate the turnover period in the collapse phase, we cannot estimatethe suitable time for the stock trading. The Wavelet Analysis estimates the highest and lowest price inthe long period. However the Wavelet Analysis is sometimes misreading the turnover. Our modifiedmethod seeks to overcome the weak points of Grandville and Wavelet methods. This new method canrestrain stock trading in the collapse period. Moreover, the stock can be purchased in the lowest pricewith this method. In the simulation, the price rose after buying the stock. The result of the simulationmade average profit over 35 % of the capital in 7 stocks. This profit was greater by 10% than that of theconventional Granville's law.
