Evidências empirícas sobre a relação entre EVA e Retorno Acionário nas empresas brasileiras - Empirical evidence on the relationship beween EVA and Stock Returns in brazilian firms
Abstract
This paper provides empirical evidence on the relationship between Economic Value Added (EVA) and stock returns in Brazilian firms. This relationship between these variables has been subject to controversy in recent years, with some authors finding significant associations between them while others find none. The hypothesis that EVA affects stock returns is tested through linear regression, using alternative models. The sample is comprised of companies that are traded on the most important Brazilian stock exchange. A comparison of the outcomes of our study with those of previous studies shows that significant results depend on determination of the appropriate variables (stock returns versus stock prices), as well as of the correct dynamic structure between the dependent and the explanatory variable.
