We analyzed the Standardized Financial Statements (SFS), Annual Reports (AR) and Sustainability Reports (SR) in the period from 2007 to 2011. The results indicate the existence of significant and positive relationship between voluntary disclosure economic and market value of companies, the same is not true with regard to voluntary disclosure environment that has a significant relationship, but negative in relation to Tobin's Q, demonstrating a trade vision-off between the investor and the manager, as such disclosure is strategically important from the viewpoint of business management. No evidence of a significant relationship between social voluntary disclosure and market value of companies. The study could help to encourage companies to voluntarily disclose information of an economic, social and environmental both quantitative and qualitative, as a strategic, yet aligned their mission and values as a way to communicate with their stakeholders and through that channel as to obtain benefits efficiency in management and business continuity expectations, given the enforcement of regulatory bodies, society and other agents that interfere in business and have direct legitimate. This incentive represents compensatory and contingency measures can reduce risks and transmit corporate responsibility and follow a global trend, which considers factors involving actions of a social and environmental function as extensions of social enterprises / Este estudo analisou a rela????o existente entre o valor de mercado (mensurado pelo Q de Tobin) e a divulga????o volunt??ria de informa????es econ??micas, sociais e ambientais, em relat??rios de sustentabilidade das companhias listadas na BM&FBovespa. Foram analisados, as Demonstra????es Financeiras Padronizadas (DFPs), os Relat??rios Anuais (RA) e os Relat??rios de Sustentabilidade Empresarial (RSE), no per??odo de 2007 a 2011. Os resultados apontam a exist??ncia de rela????o significante e positiva entre a divulga????o volunt??ria econ??mica e o valor de mercado das empresas; o mesmo n??o se d?? em rela????o ?? divulga????o volunt??ria ambiental que possui rela????o significante, por??m negativa em rela????o ao Q de Tobin, demonstrando um trade-off entre a vis??o do investidor e do gestor, pois tal divulga????o ?? estrategicamente relevante do ponto de vista da gest??o dos neg??cios. N??o h?? evid??ncia de rela????o significante entre a divulga????o social volunt??ria e valor de mercado das companhias. O estudo poder?? contribuir para incentivar as companhias a divulgar informa????o volunt??ria de natureza econ??mica, social e ambiental tanto quantitativa como qualitativa, como medida estrat??gica, por??m alinhada ?? sua miss??o e valores como forma de se comunicar com seus stakeholders e atrav??s desse canal obter vantagens quanto ?? efici??ncia na gest??o e nas expectativas de continuidade dos neg??cios, atendendo ao enforcement de ??rg??os reguladores, da sociedade e de demais agentes que interferem nos neg??cios e possuem direitos leg??timos. Tal incentivo representa medidas contingenciais e compensat??rias capazes de reduzir riscos e transmitir responsabilidade corporativa e acompanham uma tend??ncia global, a qual entende os fatores que envolvem a????es de car??ter ambiental e social como extens??es da fun????o social das empresas
