Recent evidence shows that option volatility skews and volatility spreads between call and put options predict equity returns. This study investigates whether such predictive ability is driven by option traders' information advantage. We examine the predictive ability of volatility skews and...

This paper investigates the relationship among trading volume around earnings announcements, earnings forecast errors, and subsequent returns. Prior research finds a positive relation between earnings announcement period trading volume and subsequent returns (the high-volume return premium) and...

Consistent with prior studies, this study shows that extremely negative and extremely positive earnings surprises in the fourth quarter have lower levels of persistence than those in the first through third fiscal quarters. Furthermore, extremely negative earnings surprises in the fourth fiscal...

This study explores an additional factor that is associated with differential levels of the post-earnings-announcement drift (henceforth drift) - the contemporaneous surprise in revenues. Consistent with prior evidence about greater persistence of revenues and greater noise caused by...

Post-earnings-announcement drift is the well-documented ability of earnings surprises to predict future stock returns. Despite nearly four decades of research, little has been written about the importance of how earnings surprise is actually measured. We compare the magnitude of the drift when...

This study explored the accrual anomaly. The study is unique because it analyzed originally reported - unrestated - quarterly data for 1991 through the first quarter of 2004 to calculate accruals and used U.S. SEC filing dates to identify the day on which investors first obtained information...

The study reported here consisted of estimating earnings and sales (or revenue) surprises either with historical time-series data or with analyst forecasts. Post-earnings-announcement drift was found to be stronger when the revenue surprise was in the same direction as the earnings surprise....

This study utilizes firm-specific time-series data to estimate the economic value of the Research and Development (Ramp;D) expenditures that investors consider an asset to the firm. The study uses a modification of the Ohlson (1995) model to estimate the persistence of abnormal earnings, the...

This study examines the disclosure of labor-related costs by US firms, and estimates the proportion of these costs that are valued as an asset (human capital) by the market. Separate identification of labor-related costs in US financial reports is voluntary, and is made consistently only by...

This study empirically investigates the information dynamics of the Ohlson valuation framework. Single-period lagged linear autoregressive relationships among dividends, earnings, and book values of equity are estimated for a sample of stochastically stationary firms and are found not to support...
