We build an equilibrium model to explain why stock return predictability concentrates in bad times. The key feature is that investors use different forecasting models, and hence assess uncertainty differently. As economic conditions deteriorate, uncertainty rises and investors' opinions...

Assuming that risk premiums are determined by failure risk, we present a stylized model of interactions among risk-proxy variables, external financing, and stock returns in which a common mispricing factor, involving operating profit and external financing, drives the following five asset...

I set up a model in which two types of ambiguity-averse traders disagree on how to interpret a public signal. When traders first observe contradicting interpretations of the signal, they don't know whether to attribute the clash of opinions to different information processing or to information...

In this paper, we document evidence that downside betas tend to comove more than upside betas during a financial crisis, but upside betas tend to comove more than the downside betas during financial booms. We find that the asymmetry between Downside-Beta Comovement and Upside-Beta Comovement is...

This paper compares several investment strategies designed to exploit the low-beta anomaly. Although the notion of buying low-beta stocks and selling high-beta stocks is natural, a choice is necessary with respect to the relative weighting of high-beta stocks and low-beta stocks in the...

Long-short anomaly returns are strongly related to the day of the week. Anomalies for which the speculative leg is the short (long) leg experience the highest (lowest) returns on Monday. The opposite pattern is observed on Fridays. The effects are large; Monday (Friday) alone accounts for over...

We examine whether the results supporting the sentiment-related overpricing story by Stambaugh, Yu, and Yuan (J. Financial Economics, v.104, p.288-302) is still valid after controlling for macroeconomic conditions. We no longer find the results consistent with the sentiment-related overpricing...

In this paper, we confirm cross-sectional reversals in intraday returns in China's A-share market. Intraday reversals are shown to be robust with respect to seasonality, alternative samples, and the daily price-limit rule. To investigate the potential drivers, trade volumes and order imbalances...

Motivated by the observation that elderly liquidate their mutual fund holdings regularly, we examine whether mortality patterns have a predictable impact on aggregate mutual fund flows and asset prices. Our key conjecture is that periods with high mortality rates would be associated with higher...

We provide new evidence on investor disagreement based on a model where investors observe public information but agree to disagree on its interpretation. Specifically, we measure firm-level investor disagreement by the intraday volume-volatility elasticity around corporate news announcement. A...
