摘要：We summarize the fifty-year history (1968-2017) of the Ibovespa, a gross total return index that comprises the most liquid stocks traded on the São Paulo Stock Exchange in Brazil. We provide contextual material on the Brazilian economy during this 50-year period (such as the fight against hyperinflation, the privatization of companies, and economic crises) and its impact on the index composition and performance. We discuss the effect of the change in the index calculationmethodology that took place in 2014, when companies with lower market capitalization became less representative in the index. Finally, we discuss the representativeness of each industry on the Ibovespa portfolio.
