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...

This paper reports two empirical regularities regarding trading volume prior to earnings announcements. The literature suggests that discretionary liquidity traders postpone their equity trading until firms publicly announce earnings due to high information asymmetry before anticipated...

We use Yahoo Finance search to examine the effects of investor attention at earnings announcements. We find that Yahoo Finance search at earnings announcements is a major factor explaining earnings responses and is predictive of subsequent returns. Moreover, we show that other measures of...

“Sticky” ownership (including passive, insider, and long-term ownership) could hurt short-sellers by reducing the supply of shares available to buy-to-cover their positions. We examine the adverse effect of sticky ownership on short covering by focusing on the trading around earnings...

This study examines whether firms’ political activism induces bias in the media’s coverage of earnings announcements and how such coverage impacts markets. We infer firm political ideology based on employee political contributions, and identify firm and manager characteristics associated...

We examine the impact of accounting quality, used as a proxy for information risk, on the behavior of equity implied volatility around quarterly earnings announcements. Using US data during 1996-2010, we observe that lower (higher) accounting quality significantly relates to higher (lower)...

Firm disclosure of order backlog (OB) is considered important to assess future sales and profits. The extant literature on OB has generally documented positive associations between increases in OB and market returns. These associations were based on annual disclosures of backlog in 10-K filings,...

We develop a measure of how information events impact investors' perceptions of risk that is broadly applicable and simple to implement. We derive this measure from an option-pricing model where investors anticipate an announcement that simultaneously conveys information on the announcer's...

We use trade-level data to examine the role of actively managed funds (AMFs) in earnings news dissemination. We find AMFs are drawn to, and participate disproportionately more in, earnings announcements (EAs) that include bundled managerial guidance. When the two pieces of news are directionally...
