The effect of earnings surprises on information asymmetry

We examine the effect of earnings surprises on changes in information asymmetry. We hypothesize and find that asymmetry is lower (higher) in the quarter following positive (negative) earnings surprises compared to firms that meet the consensus analyst earnings forecast. The relations between earnings surprises and information asymmetry are stronger when the surprises are more likely to capture investors’ attention. Examining the source of these changes, we show that decreased information search activities is the most important factor for asymmetry declining after positive surprises; for negative surprises, decreased uninformed trading plays a dominant role increasing asymmetry.     

基于佣金收入动机的机构投资者盈利预测偏离与股票交易量研究

本文基于信息反应模型研究了机构投资者盈利预测偏离与普通投资者交易需求之间的激励关系,并选取2006至2010年的相关盈利预测和股票交易数据进行实证分析。结果表明,机构投资者的盈利预测存在显著偏离前期市场平均预测值的倾向,而且这种偏离倾向会进一步诱发股票交易增量,从而增加机构投资者的佣金收入。这意味着普通投资者在参考机构投资者的盈利预测报告时,需要考虑其基于刺激交易量的自利因素。     

Fool's mate: What does CHESS tell us about individual investor trading performance?

We investigate the short‐term relation between individual investor trading and stock returns on the Australian Securities Exchange. Stocks heavily bought by individual investors underperform stocks heavily sold over the subsequent three days, with respective returns on to a long–short portfolio of ?93, ?67 and ?12 basis points on days one, two and three. Individuals underperform in small and mid‐size stocks when they trade passively using limit orders waiting for the market price to move in their favour. Individuals underperform in large stocks when they trade aggressively using marketable orders. Foreign institutions gain from taking the opposite side of individual trades. We present an information asymmetry‐based explanation for the findings.     

Who moves the stock market in an emerging country – Institutional or retail investors?

By analyzing the dynamic behavior of institutional and retail investors in the Indonesia Stock Exchange using their completed transactions (comprising over 250 million observations), this study highlights that their trading strategies and behavior, in which institutions play a more important role than individuals in the market, are indeed different. Specifically, past trading activities by individual (institutional) investors have significantly affected the current trading behaviors and strategies of individual investors (both investor types). Furthermore, retail (institutional) investors are most likely to perform contrarian (momentum) strategies and trade frequently (infrequently) with small (large) amounts of money and short (long) holding periods.     

Liquidity,liquidity risk,and information flow: Lessons from an emerging market

This paper examines the role of public and private information flows in intraday liquidity and intraday liquidity risk in the Tunisian stock market. Our empirical results are based on ARMA and GARCH-type models and show that, for major Tunisian stocks, gradually elapsed public information together with gradually elapsed private information in the market is the dominant factor in liquidity improvements in the Tunisian stock market. Liquidity improvements are generated by a decrease in the bid-ask spread accompanied by an increase in the depth at best limit. Our results clearly indicate that the arrival of public information in a sequential manner is the dominant factor generating increases in liquidity risk related to the bid-ask spread, while the advent of private information in a contemporaneous manner is the dominant factor generating increases in liquidity risk related to the depth at best limit. Additionally, our results show that liquidity risk persistence disappears when trading volume and order imbalance are included as explanatory variables in the conditional variance equation.     

Information asymmetry,mutual funds and earnings management: Evidence from China

This paper investigates how information asymmetry and mutual fund ownership affect listed companies’ earnings management. We show that (1) reducing information asymmetry improves firms’ earnings management behavior; (2) relative to short-term mutual funds, long-term mutual funds promote earnings quality by adopting a monitoring role; and (3) by dividing firms into high/low information asymmetry groups, we find that the information environment significantly increases the effect of long-term mutual funds on firms’ earnings management. In this paper, we provide new evidence for the role that institutional investors play in a typical emerging capital market. Our results have clear policy implications: to increase earnings quality, it is essential to improve information transparency and develop long-term institutional investors.     

Does revenue momentum drive or ride earnings or price momentum?

This paper examines the profits of revenue, earnings, and price momentum strategies in an attempt to understand investor reactions when facing multiple information of firm performance in various scenarios. We first offer evidence that there is no dominating momentum strategy among the revenue, earnings, and price momentums, suggesting that revenue surprises, earnings surprises, and prior returns each carry some exclusive unpriced information content. We next show that the profits of momentum driven by firm fundamental performance information (revenue or earnings) depend upon the accompanying firm market performance information (price), and vice versa. The robust monotonicity in multivariate momentum returns is consistent with the argument that the market does not only underestimate the individual information but also the joint implications of multiple information on firm performance, particularly when they point in the same direction. A three-way combined momentum strategy may offer monthly return as high as 1.44%. The information conveyed by revenue surprises and earnings surprises combined account for about 19% of price momentum effects, which finding adds to the large literature on tracing the sources of price momentum.     

Strategic timing of annual earnings announcements: evidence from an order-driven market

Using Spanish data, this paper examines, for the first time, the differences in the intraday response of an order-driven market to earnings announcements made during trading and non-trading hours. We show that the speed of reaction depends on timing of the announcement: for overnight (daytime) announcements, the improvement in liquidity is (not) immediate. This finding could explain why Spanish firms prefer to release the bad (good) earnings announcement in trading (non-trading) hours. This strategic timing differs from the traditional disclosure policy in American markets, suggesting that different microstructures may react differently to news releases and, consequently, drive the strategic timing of corporate disclosures.

Who monitors opaque borrowers? Debt specialisation,institutional ownership,and information opacity

In this study, we suggest that the level of information opaqueness determines the propensity of publicly listed firms to have debt financing from only a few debt types (i.e., debt specialisation). Using accruals quality as a proxy for information opaqueness, we find that the degree of debt specialisation is lower for firms with high-quality accruals. This result is consistent with the notion that information collection and monitoring costs are higher for firms that have higher informational opacity, explaining the tendency towards debt specialisation. We further argue that creditors need not monitor borrowers so closely when they are monitored by institutional owners. The empirical findings support this argument and show that firms with more stable institutional ownership are likely to have less specialised debt types. The empirical evidence is also consistent with the expectation that stable institutional ownership is likely to reduce the demand for monitoring over accruals management. Using S&P 500 membership as an exogenous event driving institutional ownership changes, we further document that debt specialisation is decreasing in accruals quality when institutional investors are expected to have an influence.     

Do auditing standards improve the accounting disclosure and information environment of public companies? Evidence from the emerging markets in China

In this paper, we investigate the impact of the implementation of a set of new auditing standards in 1996 on the information environment in the emerging markets in China. Because the implementation of such standards can increase the quality and/or quantity of accounting disclosures, it can be conceptualized as an improvement in the information environment of public companies. We investigate the improvement in accounting disclosure and information environment from both the market perspective and the accounting perspective. First, consistent with the information economics literature (e.g., [Holthausen, R., & Verrecchia, R., (1990). The effect of informedness and consensus on price and volume behavior. The Accounting Review, 65, 191–208]), we find that companies experience a significant increase in trading volume and price volatility subsequent to the implementation of the standards. Second, consistent with the literature on earnings management (e.g., [Chen, C. W. K., & Yuan, H. Q., (2004). Earnings management and capital resource allocation: evidence from China's accounting-based regulation of right issue. The Accounting Review, 79, 645–665, Jian, M., & Wong, T. J., (2004). Earnings management and tunneling through related party transactions: evidence from Chinese corporate groups. Working Paper, Nanyang Technological University and Hong Kong University of Science and Technology]), we find a decrease in earnings management and, hence, an increase in quality of earnings. Finally, we find a decrease in the synchronicity of stock prices and, hence, an increase in the quality of firm-specific information available to investors, which is consistent with the literature on price synchronicity (e.g., [Morck, R., Yeung, B., & Yu, W., (2000). The information content of stock markets: why do emerging markets have synchronous stock price movements? Journal of Financial Economics, 58, 215–260]). Our results have significant implications for standard setters, regulators, researchers, managers, and investors in general and those in the emerging markets in particular.     

The volume–volatility relationship and the opening of the Korean stock market to foreign investors after the financial turmoil in 1997

This paper investigates the stock volatility–volume relation in the Korean market for the period 1995–2001. Previous research examined the impact of liberalization on the Korean stock market up to the period before the financial turmoil in 1997 although the crucial measures of the liberalization were introduced after the crisis under the International Monetary Fund program. One of the major features of the reformation was the financial opening to foreign investors. In this study the ‘total’ trading volume is separated into the domestic investors’ and the foreign investors’ volume. By doing this the information used by two different groups of traders can be separated. Further, in addition to the absolute value of the returns and their squares we use the conditional volatility from a GARCH-type model as an alternative measure of stock volatility. The following observations, among other things, are noted about the volume–volatility causal relationship. First, for the entire period there is a strong bidirectional feedback between volume and volatility. In most cases this causal relationship is robust to the measures of volume and volatility used. Second, volatility is related only to ‘domestic’ volume before the crisis whereas after the crisis a bidirectional feedback relation between ‘foreign’ volume and volatility begins to exist. In other words, ‘foreign’ volume tends to have more information about volatility in recent years, which suggests the increased importance of ‘foreign’ volume as an information variable.      

Accounting conservatism in a setting of Information Asymmetry between majority and minority shareholders

Following LaFond and Watts (2008), we examine the relation between information asymmetry (as measured by PIN, probability of information-based trading) and accounting conservatism but focus on a country – Taiwan – whose institutional background is different from that of the United States. Due to the disparate degree of conservatism across the world, the conclusions of LaFond & Watts (2008) might not be universally applicable. Our findings support, in general, the applicability of their conclusion to a Taiwan data set. We find, however, that the effect of PIN appears weaker when auditor tenure is taken into account, thus supplementing their conclusions.
