AIP Conference Proceedings, v. 1470, p. 218-221, 2012.1551-7616https://repositorio.fei.edu.br/handle/FEI/4125This paper presents a methodology to detect significant changes in the price of U.S. dollar in regarding to the stock exchange using the Haar wavelet as well as statistical analyzes of several parameters. The data used arise of information provided by the stock market, both for the U.S. dollar and for the stock market. The results show that the applied methodology through Haar wavelet, are able to inform in advance the trend of the stock market through a single variable, the U.S. dollar. © 2012 American Institute of Physics.Acesso RestritoArtigo de evento10.1063/1.4747679DollarHaar WaveletOverreactionUnderreaction
