Earnings Announcements and the Components of the Bid-Ask Spread


Book Description

This study investigates the behavior of the components of the bid-ask spread around earnings announcements. The authors find that the adverse selection cost component significantly increases surrounding the announcements, while the inventory holding and order processing components significantly decline during the same periods. Their results suggest that the directional change in the total bid-ask spread depends on the relative magnitudes of the changes in these three components. Specifically, the decreases in inventory holding costs and order processing costs imply that earnings announcements may have an insignificant impact on the total bid-ask spread, even when they result in increased information asymmetry.Copyright 1996 by American Finance Association.










Earnings Quality


Book Description

This review lays out a research perspective on earnings quality. We provide an overview of alternative definitions and measures of earnings quality and a discussion of research design choices encountered in earnings quality research. Throughout, we focus on a capital markets setting, as opposed, for example, to a contracting or stewardship setting. Our reason for this choice stems from the view that the capital market uses of accounting information are fundamental, in the sense of providing a basis for other uses, such as stewardship. Because resource allocations are ex ante decisions while contracting/stewardship assessments are ex post evaluations of outcomes, evidence on whether, how and to what degree earnings quality influences capital market resource allocation decisions is fundamental to understanding why and how accounting matters to investors and others, including those charged with stewardship responsibilities. Demonstrating a link between earnings quality and, for example, the costs of equity and debt capital implies a basic economic role in capital allocation decisions for accounting information; this role has only recently been documented in the accounting literature. We focus on how the precision of financial information in capturing one or more underlying valuation-relevant constructs affects the assessment and use of that information by capital market participants. We emphasize that the choice of constructs to be measured is typically contextual. Our main focus is on the precision of earnings, which we view as a summary indicator of the overall quality of financial reporting. Our intent in discussing research that evaluates the capital market effects of earnings quality is both to stimulate further research in this area and to encourage research on related topics, including, for example, the role of earnings quality in contracting and stewardship.




The Bid-Ask Spread's Cost Components


Book Description

We develop and test a model that provides improved estimates of the bid-ask spread's cost components: order processing, adverse selection, and inventory control. The model incorporates three unique features: (1) a dealer's response to inventory imbalances is not static but depends on the size of the imbalance and the dealer's aversion to inventory risk; (2) active inventory management by a dealer will result in a stationary stochastic process for inventory; and (3) inventory management will influence the adverse selection cost component. We estimate the spread's components using intraday data for NYSE/AMEX and NASDAQ stocks. We also examine the impact of our model's features on the cost estimates. The results suggest inventory costs are higher and order processing costs are lower than previously reported.










Adverse Selection and Re-Trade


Book Description

Many securities are traded repeatedly by asymmetrically informed investors. We study how current and future adverse selection affect the required return. We find that the bid-ask spread generated by adverse selection is not a cost, on average, for agents who trade, and hence the bid-ask spread does not directly influence the required return. Adverse selection leads to trading-decision distortions, however, implying allocation costs, which affect the required return. We derive explicitly the effect on required returns, and show that our result differs from models that consider the bid-ask spread to be an exogenous cost.
