Most corporate news occurs in the after-hours market, a very illiquid trading environment. We examine the relationship between liquidity and price discovery around after-hours earnings announcements. Prices reflect earnings surprises through changes in quotes rather than through trades....

We examine the impact of the surge in trading activity following FOMC announcements on price discovery in the equity market, in particular in the highly liquid S&P 500 E-mini futures. In contrast to the hypothesis that all trading reflects learning about these public news announcements, we find...

Stock exchanges compete for order flow through their fee models. A traditional model pays rebates to liquidity suppliers, and an inverted model pays rebates to liquidity demanders. Using a regulatory intervention to examine the interaction between tick size, restrictions on dark trading, and...

In an effort to increase transparency, the Chair of the Federal Reserve now holds a press conference following some, but not all, FOMC announcements. Evidence from financial markets shows that investors lower their expectations of important decisions on days without press conferences and that...

From 2010--2015, a group of traders illegally accessed earnings information hours before their public release by hacking several major newswire services. We use their informed trading as a natural experiment to investigate how efficiently markets incorporate private information in trades. 15\%...

Mutual fund returns are predictable when the Net Asset Value is computed from prices that do not reflect all available information. This problem was brought to the public eye with the late trading and market timing scandal of 2003, which led to SEC intervention in 2004. Since these events,...

We examine the speed and mechanism of the price discovery process following earnings announcements in the after-hours market, a very illiquid trading environment. Prices reflect earnings surprises mostly through changes in quotes rather than through trades. Following positive announcement...

FOMC announcements cause substantial trade volume in equity markets. Is such volume mirroring information flow? Using a new diagnostic to quantify information flow net of noise, we show equity prices following FOMC announcements are less informative about future indicative prices than those...

We provide a novel framework and empirical results to understand the relation between profitability growth and returns. By connecting a concave profit function to a standard valuation framework, we argue that if growth-rate risk carries a positive risk premium, firms with higher current...
