I dissect stock returns after earnings announcements into their overnight and intraday components and document strong positive abnormal overnight returns for several weeks after both large positive and negative earnings surprises. This finding is in line with attention-induced buying pressure....

Research shows that stocks with fluent names trade at higher prices. However, it is not clear whether fluency simply appeals to naive investors, or actually identifies better firms. In this paper, we disentangle these two explanations. Consistent with our theoretical model, we find that the...
