Resumo


This research aims to propose an index of informational asymmetry and create a ranking with publicly traded firms in a market analysis that can be used in several studies in corporate finance. The proposed method consists in the construction of an algorithm based on the Elo rating and capture the perception of the analyst that choose, between two firms, the one they consider to have better information. After having two different indexes built on two distinct dates and by different analysts, it was confirmed the consistence of the method once the Spearman rank-order correlation between different combinations of indexes was higher than 70%. This index is a good proxy for use as a measure of disclosure of Brazilian firms and it will help the development of the theory and greater understanding of the impacts of disclosure on many aspects related to finance as value and cost of capital.
