This paper examines to what extent stock market anomalies are driven by firm fundamentals in an investment-based asset pricing framework. Using Bayesian Markov Chain Monte Carlo (MCMC), we estimate a two-capital q-model to match firm-level stock returns, instead of matching portfolio-level...

This study examines the effect of option volume relative to stock volume (O/S) on market response to earnings surprises. The market reaction per unit of earnings surprise is lower for firms that have high O/S prior to earnings announcement than for firms with low O/S prior to earnings...

We study the role of firm ambiguity on stock price reaction to earnings announcements. By using the firm's variance risk premium (VRP) prior to earnings news arrivals as a proxy for firm-level information ambiguity, we provide evidence that this “micro” form of ambiguity has a significant...

Prior studies show that investor learning about earnings-based return predictors from academic research erodes return predictability. However, the signaling power of “bottom-line” earnings has declined over time, which complicates assessments of investor learning about profitability signals...

Employing a broad sample of US firms over the period 1962 to 2009, we provide evidence of a liquidity risk impact on the fundamental earnings-returns relation. Specifically, we document that current liquidity risk has a positive moderating effect on the relation between current returns and next...

We reexamine the time-series properties and determinants of the relation between aggregate earnings and returns (earnings response coefficient, ERC) employing return decompositions with longer historical data. We find that aggregate ERC is time-varying, above and beyond the evidence documented...

The Post-Earnings Announcement Drift (PEAD) anomaly refers to the tendency of stock prices to continue drifting in the same direction as earnings surprises well through the subsequent earnings announcements; ignoring the autocorrelations in extreme earnings surprises across adjacent quarters....

We provide the first large-scale study of the performance of expected-return proxies (ERPs) internationally. Analyst-forecast-based ICCs are sparsely populated and not robustly associated with future returns. Earnings-model-forecast-based ICCs are well-populated, but are unreliable outside the...

I show that variation in economy-wide uncertainty causes asymmetric stock price responses to firm earnings surprises. The uncertainty that attends bad earnings news that arrives during expansions with greater economy-wide uncertainty occasions larger price declines. This is because news...
