description This paper investigates the role of investor attention in predicting future stock market returns for Brazilian stocks using Google Search Volume (GSV). We tested whether lagged variations in GSV are followed by changes in excess returns by testing 57 stocks from the Ibovespa using weekly search data from Google Brazil from 2014 to 2018. Similar to previous research on the U.S. market, we found that increases in GSV are followed by lower excess returns. Additionally, we show that the more traded a stock is, the higher the effect. This is consistent with the hypothesis that higher individual investor attention leads to lower subsequent returns, suggesting that increasing popularity causes stock prices to deviate from their fundamental value.
