EVA is a measure which assesses companies´ performance in terms of value generation to the shareholders. It is a methodology fairly used in the North- American market and which has been gaining space in the Brazilian market. The relation of the EVA with the market value and the companies´ performance has been the subject of many studies in the last years, both in the North-American and Brazilian markets, sometimes generating controversial results. Within this context, this research has as its main objective to test, through linear regression models, the relation between the EVA and the companies´ performance in the Brazilian Market during the period of 1995 to 2004. The sample contemplates all companies which compound the IBR-X (Index with the one hundred most traded stocks in the Bolsa de Valores de São Paulo) and that have a minimum record of five years of traded stocks, with the exception of financial institutions. The result observed was that in fact there is a correlation between the EVA and the companies´ performance in the Brazilian market, however, this correlation is statistically low, despite of its growing tendency shown in the tests throughout the years.
