RESUMO

The research aimed to test whether Brazilian futures prices follow a random walk - one of the versions of the Efficient Market Hypothesis. Futures prices of the Ibovespa index and dollar futures contratacs have been analysed, from June-30-1994 to December-31-1998. Parametric and non-parametric procedures involving Lo-MacKinlay´s Variance Ratio lead to the hypothesis not being rejected, pointing to efficiency in those markets.
