The understanding of competitive advantages is one of the major theoretical questions in strategy research. It is known that strategic resources generate competitive advantage and that the disclosure of strategic information in a transparent way, mainly of resources, values the organization for investors and works as an attraction. Within this context, it was analyzed whether the dissemination of strategic resources influences the performance of organizations. Twenty companies from the São Paulo Stock Exchange of the most profitable sector of B3 from 2010 to 2018 were part of the analysis. A qualitative approach is adopted through a detailed analysis of the strategic resources of the Reference Forms. This analysis was carried out with the aid of Atlas TI software. After this step the number of disclosure of strategic resources was compared with the performance measured by ROE. The study contributes to the evolution of strategy research in relation to RBV and Theory of Disclosure and, as a practical contribution, to assist in the strategic choice of disclosed information. It was concluded that the disclosure of strategic resources does not influence the performance of the sample companies.
