This study constructs the institutional- and individual-based probability of informed trading (PIN) by adjusting Easley, Hvidkjaer and O'Hara (2002) and investigates the impact of the informed trading behaviors of institutions and individuals on the post-announcement drift around the earnings...

We analyze the earnings information and stock prices of S&P500 firms and find that investors following S&P500 stocks (i) respond more to pro forma earnings than to GAAP earnings, (ii) respond to an emphasis on pro forma earnings, and (iii) are fixated on pro forma earnings. We provide the first...

We test the proposition in Johnstone (2016) that new information may lead to higher, rather than lower, uncertainty about firms' future payoffs. Based on the Bayesian rule, we hypothesize earnings news that is inconsistent with investors' prior belief will lead to higher market uncertainty....

We examine the impact of distance on Internet search, and the effect of the “local bias” in search on the stock market response around earnings announcements. We find significant local bias in search behavior. Motivated by theories explaining local bias, local information advantage and...

I test whether the anticipation of earnings news stimulates acquisition of customer information and mitigates returns to the customer–supplier anomaly documented by Cohen and Frazzini. I find that attention to a firm's publicly disclosed customers increases shortly before the firm announces...

Firms depend on information technology to provide high quality internal information, but prior research suggests that IT is underutilized. Prior research suggests that when CEOs have experience with IT, then IT is more likely to be accepted throughout their firms. We take these arguments a step...

I test whether the anticipation of earnings news stimulates acquisition of customer information and mitigates returns to the customer-supplier anomaly documented by Cohen and Frazzini (2008). I find that attention to a firm's publicly disclosed customers increases shortly before the firm...

Recent research finds that many analyst recommendation revisions take place shortly after earnings announcements. Altinkilic and Hansen (2009) attribute the clustering of recommendations to analysts strategically piggybacking on earnings information to improve the perceived performance of their...

I propose to use volatility to infer opportunistic insider sales. I argue that insider sales occurring when volatility is low are suspicious and that these suspicious sales are likely to be driven by insiders’ private information for the following reasons. Suppose that insider sales are not...

The purpose of a management earnings forecast is to forecast the eventual earnings figure released to the market at the earnings announcement date. To the extent that management earnings forecasts should reduce periodic shocks by reducing information asymmetry, stock return volatility is...
