Análise da criação de valor : um estudo multicaso nas empresas nordestinas listadas na BOVESPA

Abstract

This work aims to analyse the value creation of the publicly traded firms from northeast of Brazil over 2005 2009 years, using Economic Value Added (EVA) as the financial measure. The most difficult process in EVA method was to calculate the cost of equity and to solve that problem it was used the CAPM method with the adaptation suggested by Damodaran (2005) to emergent countries as Brazil. The universe of the research was composed of 48 firms listed on São Paulo Stock Exchange (BOVESPA) but, after some exclusion criteria, 23 firms remained to be analyzed. The accounting statements were brought up to date with the whole consumer price index (IPCA) to guarantee the same purchase power. It was not noted the optimal structure of capital in any debt to equity ratio, what confirmed the Modigliani and Miller principles. It was calculated the weighted asset average capital (WACC) of every northeast firms and compared their results with the biggest firms from the same sector, according to EXAME Maganize (2009). The firms that created or destroyed value were identified and it was established a ranking with the best ones. The firms from Rio Grande do Norte, Sergipe and Bahia States have obtained a performance almost twofold higher than others.
