We discover three significant periodicities in the autocorrelation of intraday stock returns. We demonstrate that (i) the autocorrelation is 64% more negative during afternoons than during mornings, (ii) the autocorrelation is more negative Tuesdays through Fridays than on Mondays, (iii) overall...

This paper employs the real option approach (ROA) to study the investment decision of a management accounting innovation—the case of activity-based costing (ABC)—adoption or discontinuation under uncertainty. We argue that investing in ABC is analogous to having the option rights in a...

We construct a direct measure of U.S. based foreign sentiment using flow shifts between U.S. and international mutual funds. Foreign sentiment predicts return reversals in international markets, while local sentiments predict reversals in local markets. Exploring this segmentation, we find that...

We analyze a model of anomaly discovery and test its new predictions on both asset prices and arbitrageurs' trading. Consistent with existing evidence, the discovery of an anomaly reduces its magnitude and increases its correlation with other anomalies. Using 99 anomalies, we test the new...

Positive return correlation signals slowly-diffusing information. Short sell-constrained institutions are mainly informed in their buy trades. Building on these facts, we identify informed investors ex ante by focusing on mutual funds. We propose a measure of the dynamic excess autocorrelation...

Stock-level liquidity shocks not only affect the transaction costs institutional investors face but also generate mispricing opportunities. We find that institutions increase (decrease) their trading intensity when liquidity improves (declines). Further, active institutions trade to take...
