This work analyzes the mean quarterly returns produced by portfolios, selected between 2002 and 2010, compounded by stocks traded in the BM&FBovespa, based on the use of two popular multiples, Price/Earnings (P/E), or Price/Book Value (P/B), aiming at verifying whether these returns were consistently higher than the mean valuation of the Bovespa‟s index. Thus, by investigating the possible existence of a market anomaly, this study fits in the field of controversial academic debate: the Efficient Market Hypothesis (Fama, 1970). For each selected date, the shares were sorted by the selected multiple, and were divided, then, into four portfolios (by quartiles). To analyze the results, descriptive statistics were calculated, Jarque-Bera (JB) and Student tests were performed. The results suggest that portfolios formed by stocks 'P / E Very Low' (below the first quartile) were able to produce, over that period, quarterly average returns higher than the Bovespa‟s index, within a confidence interval of approximately 96.2%. In addition, portfolios formed by stocks 'P / B Low‟ or P / E Low‟ (between the 1st and 2nd quartile) produced good performance as well, but at a much lower level of confidence, set between 82,2 and 83,5%, respectively
