Análise e aferi？？o da correla？？o entre Valor Económico Acrescentado e o Valor de Mercado Adicionado num grupo empresarial cotado na NYSE Euronext

following the international trend, management practices aimed at value creation have begun to proliferate in the portuguese business environment, and the economic value added (eva？) has emerged as a prime performance measure in the control processes of implemented strategic options. in this paper, we aim to review the concept of management based on value creation to compare it with traditional evaluation methods based on book value. we make particular emphasis on eva？ and we refer to the possible correlation between this metric and the market value added (mva？). from a case study, we aim to confirm, as has been done with studies conducted in other countries, the existence of a positive correlation with statistical significance between the eva？ and the mva？ in one of the largest portuguese business groups, quoted on nyse euronext lisbon, between 2005 and 2009. there have been few empirical approaches on the issue of value creation and the correlation between it and the aggregate market value of companies listed on the nyse euronext lisbon. the growing practice of this management approach in the companies and the need to measure the results make this research highly relevant. the empirical analysis allows us to measure the performance associated with value creation for capital owners. similarly, we analyze the performance of mva？ and compare the relationship between this measure and the eva？ indicators, the net results and the operational results. we confirmed that the relationship between eva？ and mva？ is, in this case, positive, and it is also the statistically most significant variable among those considered.
