This paper finds that the majority of stock price movements remain unexplained after controlling for both public and private information. This suggests that economists' inability to explain asset price movements is the result of either noise or naive asset pricing models.

This paper shows that in asset pricing the information environment gives rise to a systematic risk factor when the informativeness of future news events varies with their content (i.e., bad news and good news are not equally informative). The paper further shows that in such cases (cross) serial...

Using high frequency data, we develop an event study method to test for level shifts in beta and measure abnormal returns for events that produce such level shifts. Using this method, we estimate abnormal returns for the Troubled Asset Relief Program (TARP) announcement and find that its...

We show that the stock market regularly and systematically receives information about company fundamentals through month-end reporting, even before the quarterly earnings announcement. Such cash-flow news concentrates at the beginning of a month and affects company announcements, analyst...

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...

This paper analyzes the reaction of interest rates and the stock market to macroeconomic news announcements (MNAs) at the zero lower bound (ZLB). I start by using a shadow rate term structure model to formulate three predictions for the sensitivity of interest rates to MNAs. First,...

Using high frequency data, we develop an event study method to test for level shifts in beta and measure abnormal returns for events that produce such level shifts. Using this method, we estimate abnormal returns for the Troubled Asset Relief Program (TARP) announcement and find that its...

Asset-pricing facts on FOMC announcements have changed strikingly in the last decade. The pre-announcement drift has disappeared, and other known facts - the announcement premium and a stronger CAPM - now concentrate on a subset of announcements. We propose these distinct patterns correspond to...

Using a news-based gauge of geopolitical risk, we study its role for asset pricing in global emerging markets. We find that changes in risk positively predict future stock returns. The countries with the highest increase in geopolitical uncertainty outperform their counterparts with the lowest...

We analyze the announcement risk premia on the US market between September 1987 and March 2023 and find that the market index exhibits average excess returns of 8.3 bps for macroeconomic announcement days. This strongly contrasts with 1.4 bps returns for non-announcement days. We further measure...
