Resumo
The purposes of this paper are to investigate the informational sophistication of foreign investors in the Brazilian stock market and to assess the price impact on local securities generated by the trading conducted by these agents. As a first finding, these agents exhibit positive and significant responses to past returns, supporting the trend-chasing hypothesis. Additionally, the results indicate a positive and significant influence of these investors on domestic price discovery, an effect that is amplified in magnitude by crisis scenarios. All these findings, combined with the fact that these agents sporadically herd, classify foreign investors as potential local price destabilizers. © 2017 Elsevier B.V.
