We propose an empirical assessment of this phenomenon. By using a measure of attention based on Google Trends, we show that an increase in the attention allocated by the market to a company is associated to a significant increase in disagreement about it. / Quando a discordância em modelos econômicas ocorre devido a interpreta- ções diferentes de sinais públicos, o nível de 'discordância de mercado' não necessariamente diminui com a chegada de um sinal público. Nós propomos uma avaliação empírica desse fenômeno. Usando uma medidade de atenção baseada no Google Trends, mostramos que um aumento na atenção alocada pelo mercado a uma company está associada a um aumento significativo da discordância sobre ela.
