Abstract in Portuguese
Esta dissertação investiga se as variações dos retornos das ações listadas na Bolsa de Valores de São Paulo podem ser explicadas por três fatores: o mercado, o tamanho da empresa e o índice Book-to-Market, ou índice B/M, definido pela relação entre o valor contábil e o valor de mercado do patrimônio líquido. A relevância destes três fatores na explicação dos retornos dos ativos foi identificada por Fama & French (1993), no estudo que conduziram no mercado americano. O estudo compreendeu as ações listadas no período 1995-2003, e todos os dados foram extraídos do banco de dados Economática, disponível no departamento de Finanças da Faculdade de Economia, Administração e Contabilidade da Universidade de São Paulo. A metodologia de teste utilizada foi idêntica àquela desenvolvida e aplicada por Fama & French (1993). Utilizou-se de retornos mensais para o cálculo dos prêmios dos fatores de risco e dos retornos das ações e carteiras, e se testou a significância do modelo e de cada um dos fatores observando-se o coeficiente de determinação, R2, e a estatística t de Student. Os resultados observados indicam que o modelo de três fatores e superior ao CAPM na explicação dos retornos das ações da amostra utilizada, e que os três fatores são significantes, se complementando na explicação dos retornos de ações de diferentes características.

Abstract in English
This dissertation analyzes whether stock retum variations can be explained by three factors: market, company size and Book-to-Market ratio, this one indicating the relation between a companys book and market value of equity. The relavance of these three factors in explaining retums was first observed by Fama & French (1993), in the research both conducted at the American stock market. This research encompassed the stocks listed at the Sao Paulo stock market in the period 1995-2003, and all data was extracted fforn the Economatica database, available at the Finance department of the School of Economics, Business Administration and Accounting at the University of Sao Paulo. The employeed test methodology was the same as the one developed and used by Fama & French (1993). Monthly retums were used in order to calculate risk factor premiums and stock and portfolio retums. The significance of the model and of each factor was tested observing the determination coefficient, R2, and the t-Student statistic. The observed results indicate that the three factor model is superior to the CAPM in the retum explanation of the sample stocks used, and that each of the factors is significant, complementing each other in the retum explanation of stocks of different characteristics.
