Prompted by concerns that high frequency traders (HFTs) reap unfair advantages over other traders by using faster trading technologies, regulators are contemplating measures to slow down equity markets. Currently, HFTs account for a significant fraction of the total market volume. Although...

We propose that extrapolative beliefs about earnings announcement (EA) returns may contribute to our understanding of EA return patterns. We construct a theoretically-motivated measure of extrapolative investors' expectations based on a stock's recent history of EA returns. We then show that...

Earnings announcements present a clear risk to investors and, under rational asset pricing theory, such risk should be consistently priced in stocks. However, we find that stocks with high earnings announcement risk earn significantly higher returns only during months when firms have earnings or...

We examine the role of concurrent information in the striking increase in investor response to earnings announcements from 2001 to 2016, as measured by return variability and volume following Beaver (1968). We find management guidance, analyst forecasts, and disaggregated financial statement...

This paper finds that low-price stocks' earnings announcement returns are significantly lower than those of high-price stocks. In contrast, we do not find such underperformance outside announcement periods. This evidence suggests that the cognitive bias induced by low share prices are corrected...

We investigate a pervasive voluntary disclosure practice -- managers including balance sheets with quarterly earnings announcements. Consistent with expectations, we find that managers voluntarily disclose balance sheets when current earnings are relatively less informative, or when future...

This paper examines how investors assimilate firm-specific earnings persistence into prices in the context of delayed stock return reactions to earnings announcements (i.e., post-earnings-announcement drift, or PEAD). The literature predicts that if investors fail to recognize fully the...

We investigate whether access to information prior to an IPO generates a trading advantage after the IPO. We find that limited partners (LPs) of venture capital funds obtain high returns when they invest in newly listed stocks backed by their funds. These returns are not explained by LPs'...

We study whether industry familiarity is an advantage in stock trading by exploring the trading patterns of industry insiders in their own personal portfolios. To do so, we identify accounts of industry insiders in a large dataset provided by a retail discount broker. We find that insiders trade...

This paper offers new evidence on informed trading around merger and acquisition announcements from the UK equity and options market. The analysis suggests that in about 25%-33% of events there is abnormal option trading volume during the month that precedes the announcement. Such evidence is...
