This study applies Johansen-Fisher panel cointegration to a sample of the most liquid shares on the Brazilian stock market for 20 years. It finds that stock prices are determined by the asymmetric information of a lagged period, and the dilution of information corrects stock prices in the current period. This shows that rational expectations theory can offer a new price measure in the rational valuation formula, and its main assumptions are met. Uninformed traders can benefit from this paper´s findings by monitoring asymmetric information.
