To operate in the Bottom of the Pyramid (BOP) markets, customized strategies are required given the specificities of the target consumer, where not only the income restriction is configured, but also the access to the product and related specifications needs to its use and location. Thus, organizations need to work with products of low prices and credit due to consumer income restriction necessarily working efficiently, lower production costs, higher production volumes and investments in distribution channels. The main publications did not reach an agreement on whether the performance in the BOP is productive or illusory, considering the various case studies and the several specific studies of strategies for BOP. Recent studies on efficiency indicated that there is no difference between them in the market, however, important authors see it, even if with great bias. Even the characterization of BOP in Brazil was placed under discussion. This research used a quantitative and qualitative approach in the analysis of the data made through electronic survey and questionnaire, which were worked through a multicriteria methodology and using as conceptual basis the Theory of Strategic Groups. Thus, the study shows that differences exist between the financial efficiencies of industries that operate or not in the BOP and presents a model of strategic dimensions that are more associated with high financial efficiency of Strategic Groups (SGs) of the furniture industry, of the clothing industry, of the food industry, of the beverage industry and of the hygiene that offer products for the extended BOP, renamed in this way by including class C in the study, unlike the initial concept of BOP. Adjacent to this main objective, this thesis evaluated the correlation of efficiencies with the main economic variables and identified which strategic dimensions are associated with the BOP-e, Non-BOP and Mixed markets of the SGs. The expectation is that the research may be one of the few significant studies that interrelate strategy and financial efficiency in the country, therefore, it seeks to advance in the theoretical field of strategies related to the BOP, as well as to present empirical data on Strategic Groups and BOP , contributing managerially with the exposure of the strategic dimensions and financial structure of the GEs that present better financial efficiency within the BOP-e, in order to be considered by the executives in their decision-making.
