Análise do desempenho de empresas brasileiras da Bovespa no período de 2006 a 2012 por meio do Sistema DuPont

Abstract

This work aimed to study the effect of 2008 crisis over Brazilian companies. In order to achieve this objective, a sample of 23 public traded companies based in Brazil was assembled, covering a period from 2006 to 2012. A number of indicators based on the DuPont system were constructed for these companies: net margin, asset turnover, financial leverage multiplier, return on assets and return on equity. These indicators had their behaviour analized during the period, by economic sector, and furthermore, the years were compared using ANOVA and Kruskal-Wallis. The results show that companies during the period being analized, adopted very distinctive strategies, which could be an indicator of an attempot to try to adapt o the possible effects of the financial crisis. Nevertheless, we could not find statistcally significant differences between the years.
