The Corporate Governance, which is a manner of overcoming the agency conflict, demands, among its principles, that the organization adopt a structure that protects the rights of the stockholders, and assure disclosure and transparency of relevant facts and their accounting demonstrations. In Brazil, in 2000, BM&FBOVESPA created differentiated levels of Corporate Governance, in order to stimulate the interest of investors, and the appreciation of companies that may voluntarily join one of the segments. Along with the preoccupation with the good practices of governance, there is another highly important and worrying issue, which refers to sustainability. More and more the investor seek companies that work under the principles of Triple Bottom Line, which involves elements of the environmental, social and economic fields, as a safety measure for their investments. In 2005, BM&FBOVESPA created the Corporate Sustainability Index (ISE), as a reference to the good practices of sustainability and commitment between the companies and the corporate sustainability. In this context, the following study aims to verify whether there are differences between the average of the monthly returns, in the period of five years, before and after, the company became involved in Corporate Governance and the Corporate Sustainability Index. The method used to test the hypothesis of the three selected samples was the Paired-Samples T Test, with the software SPSS, version 18.0. The results obtained show that in the case of the samples of ISE (p= 0,006 < 0,05) and CG_ISE (p= 0,030 < 0,05), the null hypothesis is discarded, once there is a significant difference between the average of the monthly returns, and in the case of the samples of CG (p= 0,081 > 0,05), the null hypothesis is not discarded, once there is no significant difference between the averages. Analyzing the values of the averages, it is possible to notice that most of them decrease on the second moment of the analysis. However, it is not possible to generalize by stating that the Corporate Governance and the Corporate Sustainability Index do not add value to the company and its stockholders. That happens because the economic moment coincides with the subprime mortgage crisis, which affected the major stock Exchange in the world, and strongly influenced the BM&FBOVESPA stock, especially in 2008.
