Aswath Damodaran, in his book “Investment Fables”, brings stories of investments sales that, at first sight, might seem attractive, however, when examined closely, looses its credibility. Considering the idea that a philosophy of investment based on consistent strategies and tactics is indispensable during the building of a portfolio, this study verifies if it is possible to overcome the major national market index – IBOVESPA -, at a long term, through investment strategies based on low price-earnings ratio and on the margin of safety. The reason for adopting both strategies on this study is the fact that the one based on low price-earnings ratio is restricted by not considering the growth potential and the risk of the selected companies. In fact, another portfolio has been constructed by adopting Benjamin Graham´s strategy, the margin of safety, which is capable of filtering stocks with low growth and high risk, unwanted characteristics when building a portfolio. This study suggests that it is possible to obtain a superior performance than the main national benchmark – IBOVESPA -, especially when strategies based on the margin of safety are used. The strategy based solely on the priceearnings ratio has also presented superior results than IBOVESPA, however less significant.
