We develop a novel methodology for studying the causal impact of announcement timing. Our methodology uses firms' earnings announcements and leverages quasi-exogenous variation attributable to the specific day-of-week on which a calendar month begins. We refer to the resulting variation in...

The well-known stock market adage "sell in May and go away" arose from long-term stock market seasonality in major financial markets around the globe. Kamastra, Kramer and Levy (2003) present evidence that Seasonal Affective Disorder causes this seasonality, as this condition has a profound...

This study examines how an increase in tick size affects algorithmic trading (AT), fundamental information acquisition (FIA), and the price discovery process around earnings announcements (EAs). Leveraging the SECs randomized Tick Size Pilot experiment, we show a tick size increase results in a...

Although China now has one of the largest government bond markets in the world, the market has received relatively little attention and analysis. We describe the history and structure of the market and assess its functioning. We find that trading in individual bonds was historically sparse but...

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...

This is the first study to examine the post-earnings-announcement drift anomaly in a Real Estate Investment Trust (REIT) context. The efficient markets hypothesis suggests that unexpected earnings should be fully incorporated into asset prices soon after being publicly announced. We hypothesize...

This study examines the influence of macroeconomic news on price discontinuities in the S&P 500 index futures. Results document a strong association between macro news and price jumps. Over three‐fourths of the price jumps between 8:30 am and 8:35 am and over three‐fifths of the jumps...

We characterize how informed investors trade in the options market ahead of corporate news when they receive private, but noisy, information about (i) the timing of the announcement and (ii) its impact on stock prices. Our theoretical framework generates a rich set of predictions about the...

During the first eight months of 2015, there was an ongoing debate about whether or not Greece should remain in the euro area. Using an event study approach, we quantify the effects of Grexit-related statements made by six important euro area politicians (Merkel, Schaeuble, Tsipras, Varoufakis,...
