No. of bitstreams: 1 1424220.pdf: 301206 bytes, checksum: 1f4091e3ffd5fc7ee179deb76ab824b1 (MD5) Previous issue date: 2010 / Aparentemente existe uma anomalia no mercado de ações, onde é possível prever excessos de retomo das ações baseando-se em dados passados de divulgação de lucro. Este fenômeno é estatisticamente significante e parece não ser um artefato de amostragem ou metodologia, mas de uma ineficiência de mercado. Estudos mostram uma tendência dos excessos de retornos acumulados das ações se movimentarem na direção da surpresa de lucro, e este movimento se estende por meses após a data de divulgação de lucro trimestral. Neste trabalho mostro que este fenômeno ocorre também no Brasil, mesmo utilizando uma amostra com especificidades do mercado brasileiro e utilizando dados de expectativas de lucro de analistas financeiros no lugar de previsão estatística. / Apparently, there is an anomaly in the stock market that shows that is possible to predict abnormal returns from stocks based on past earnings announcements. This phenomenon is statistical1y significant and appears not to be an artifact of sample or methodologies, but from a market inefficiency. Studies demonstrate a tendency towards accumulated abnormal retums to move toward the direction of the earnings surprise and this movement continues to weeks and even months. This study illustrates that this phenomenon also occurs in Brazil, even using a sample with Brazilian market specifications and using eamings expectations from financiaI analysts in place of statistical forecasts.
