Abstract

Based on the assertion that stock exchange returns behave differently in the face of financial crises, the objective of this research is to analyze the behavior of stock exchange returns in the countries that make up the BRICS, in 2008 and 2020, which years there were two major economic crises, subprime and COVID-19, in that order, regarding the methodological aspects, this research is classified as descriptive and of a quantitative nature. The sample used was probabilistic, using as a sample the indexes of the countries of the BRICS group and the index of the USA, the NYSE, which was used as a means of comparison for a broader view of the results. In data collection, the yahoo finance website was used as a way to obtain data. The collected data were processed and interpreted using the STATA 17.1 statistical software. It can be concluded that, in periods of crisis, markets tend to be efficient and that the volatility of one index may be somewhat influenced by another.
