We examine the relationship between the tonality of news flow and the cross section of expected stock returns. We use a comprehensive definition of media coverage that includes both financial newspapers and mass media, represented by TV broadcasts. Using the total news flow with positive and...

Does media coverage of a firm have a causal effect on the volatility of its stock price and, if so, is this of aggregate importance? This paper identifies a robust link between media coverage in the Financial Times print newspaper and a firm’s intra-day stock price volatility. This effect is...

We provide evidence that equity investors with limited attention are slow to incorporate how current oil price changes affect future earnings announcements. A cross-sectional equity trading strategy that exploits this inefficiency yields an annualized Sharpe Ratio of 0.57. Stock prices respond...

We provide evidence that an option implied volatility-based measure predicts future absolute excess returns of the underlying stock around earnings announcements and annual meetings of shareholders, even after controlling for the realized stock return volatility shortly before these information...

Stock prices following earnings announcements have become more efficient. Prices on announcement dates incorporate more quickly earnings surprises, leading to the disappearance of post-announcement price drifts. Evidence suggests that trading frictions commonly associated with market...

In this paper, I empirically test the conservatism effect of Barberis, Shleifer and Vishny (1998). Conditioning on a shock to quarterly earnings, firms ranking in the top (bottom) earnings shock quintile exhibit substantial price momentum over the next three-month periods following the initial...

We show that the post earnings announcement drift (PEAD) is stronger for conglomerates thansingle-segment firms. Conglomerates, on average, are larger than single segment firms, so it isunlikely that limits-to-arbitrage drive the difference in PEAD. Rather, we hypothesize that marketparticipants...

Over the past 12 years, financial analysts across the world have been optimistically wrong with their 12-month earnings forecasts by 25.3%. This study may be the first of its kind to assess analyst earnings forecast accuracy at all listed companies across the globe, covering 70 countries. A...

This paper investigates whether information complementarities can explain the strong patterns of sectoral comovement observed empirically. It tests the theoretical model by Veldkamp and Wolfers (2007), which suggests that firms' output decisions are based on aggregate information rather than...

Macroeconomic news announcements are elaborate and multi-dimensional. We consider a framework in which jumps in asset prices around macroeconomic news and monetary policy announcements reflect both the response to observed surprises in headline numbers and latent factors, reflecting other...
