RESUMOO presente caso de ensino evidencia a trajetória dos irmãos Pinheiro e de seus negócios de 36 anos no ramo de rede de supermercado. Trata mais detalhadamente do período de transição vivido por eles, acerca da expansão de novas filiais com inovações, desde lojas de conveniências, parque, playground e cinemas. No caso, é possível identificar aspectos que remetem ao desenvolvimento de um processo empreendedor, elaboração de estratégia deliberada a partir de estratégia emergente, gestão estratégica e mudança organizacional, para atender demandas de novos mercados, como a idealização de um shopping. Nele também é possível constatar que o desenvolvimento de um plano de expansão da rede de supermercado é algo viável e atrativo para uma pequena empresa, desde que se atue com foco estratégico e empenho para realizá-lo, mesmo com ajustes.

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.
