This study demonstrates that standard analyst coverage proxies contain information about firm-level expected returns. I decompose analyst coverage proxies into abnormal and expected components using a simple characteristic-based model and show that firms with abnormally high coverage outperform firms with abnormally low coverage by approximately 80 basis points per month. Abnormal analyst cover...

We show the cost of trading on negative news relative to positive news increases prior to earnings announcements. Our evidence suggests this asymmetry is due to financial intermediaries’ preference to reduce their exposure to risks associated with the announcements. The asymmetry creates a predictable upward bias in prices that increases pre-announcement and subsequently reverses, which confoun...

We show that proxies for firms’ incentives to manage earnings expectations toward beatable levels contain strong predictive power for earnings announcement returns. Firms with stronger incentives to manage expectations predictably underperform before, and subsequently outperform during, their expected earnings announcement months. This predictable V-shaped pattern in prices yields strategy retu...

This study examines the link between earnings announcement premia (i.e., higher returns in announcement periods) and changes in liquidity prior to the announcements. Motivated by prior research, we model market makers as holding positive inventories and show they asymmetrically raise costs of providing liquidity to sellers, relative to buyers, to reduce inventory risks ahead of earnings news. T...

In the model there are two types of nancial auditors with identical technology, one of which is endowed with a prior reputation for honesty. We characterize conditions under which there exists a \two-tier equilibrium" in which \reputable" auditors refuse bribes o ered by clients for fear of losing reputation, while \disreputable" auditors accept bribes because even persistent refusal does not c...

This study examines how accounting has informed private equity diversification claims and demand for private equity investments. Despite research showing private equity lacks portfolio diversification benefits, those marketing private equity assets continue to emphasize its diversification value, and demand for private equity investments has surged. Exploiting the change in international accoun...

We have previously demonstrated that the replacement of the S gene from an avirulent strain (Beaudette) of infectious bronchitis virus (IBV) with an S gene from a virulent strain (M41) resulted in a recombinant virus (BeauR-M41(S)) with the in vitro cell tropism of the virulent virus but that was still avirulent. In order to investigate whether any of the other structural or accessory genes pla...

The effect of base temperature variation on the heat transfer from unsteady state annular heat sink of cooling microelectronic device. Three types of the base temperature variation equations are taken in the present study. The Sine wave variation, Cosine wave variation & exponential variation of the base temperature. The finite element technique based on Galerkin method with axisymmetric rectan...
