业绩预测的取整行为研究

本文考察上市公司管理层业绩预测披露中通过取整模糊预测的行为。研究发现,上市公司在发布业绩预测时倾向于以一定基数的倍数取整,而公司的实际盈余却很少是这些基数的整数倍。进一步研究发现,当不确定性较高以及行业竞争激烈时,公司更倾向于用高基数进行取整;且取整基数的高低与业绩预测的质量相关:当取整基数更高时,业绩预测的准确性较低,且高估利润的行为更普遍;另外,公司业绩预测的取整基数越高,资本市场对预测消息的反应越弱,且对取整基数本身的反应更趋于负向。本文的研究有助于投资者更好地解读上市公司业绩预测,并为他们的投资决策提供了重要参考。     

中国上市公司自愿业绩预告动机研究

随着业绩预告制度的实施和演进,我国资本市场上逐步出现了越来越多的上市公司自愿业绩预告,这对于缓解管理层与投资者、机构投资者与中小投资者之间的信息不对称具有重要意义。那么,是什么因素激励上市公司管理层自愿披露业绩预告?通过借鉴西方的自愿信息披露理论,并结合我国转轨经济的制度背景,本文提出了我国上市公司自愿业绩预告的三类动机:资本市场交易、管理层股票收益和管理层能力信号传递,并以2001-2008年我国上市公司业绩预告数据为研究样本对此进行了检验。研究结果显示,融资需求高、管理者利益协同程度高、会计业绩好的上市公司更有动机自愿披露业绩预告,并且国有相对于非国有上市公司自愿披露动机更弱。     

Serial Correlation in Management Earnings Forecast Errors

We examine whether management earnings forecast errors exhibit serial correlation and how analysts understand the serial correlation property of management forecast errors (MFEs). MFEs should not exhibit serial correlation if managers efficiently process information in prior forecast errors and truthfully convey their earnings expectations through management forecasts. However, for long‐horizon management forecasts of annual earnings, we find significantly positive serial correlation in MFEs, and sample self‐selection does not seem to drive this phenomenon. Further analyses suggest that managers’ unintentional information processing bias contributes to this positive serial correlation. Analysts anticipate the intertemporal persistence of MFEs but underestimate the persistence level when reacting to management forecasts. Our findings have implications for market participants who rely on management forecasts to form earnings expectations, and also shed light on the efficiency of managerial decision making.     

Can Stock Recommendations Predict Earnings Management and Analysts’ Earnings Forecast Errors?

In this article we present evidence that a firm's stock price sensitivity to earnings news, as measured by outstanding stock recommendation, affects its incentives to manage earnings and, in turn, affects analysts' ex post forecast errors. In particular, we find a tendency for firms rated a Sell (Buy) to engage more (less) frequently in extreme, income–decreasing earnings management, indicating that they have relatively stronger (weaker) incentives to create accounting reserves especially in the form of earnings baths than other firms. In contrast, firms rated a Buy (Sell) are more (less) likely to engage in earnings management that leaves reported earnings equal to or slightly higher than analysts' forecasts. Our empirical results provide direct evidence of purported, but heretofore, weakly documented equity market incentives for firms to manage earnings. They are also consistent with a growing body of literature that finds analysts either cannot anticipate or are not motivated to anticipate completely in their forecasts firms' efforts to manage earnings.     

The Effect of Earnings Forecasts on Earnings Management

We develop a theory of the association between earnings management and voluntary management forecasts in an agency setting. Earnings management is modeled as a "window dressing" action that can increase the firm's reported accounting earnings but has no impact on the firm's real cash flows. Earnings forecasts are modeled as the manager's communication of the firm's future cash flows. We show that it is easier to prevent the manager from managing earnings if he is asked to forecast earnings. We also show that earnings management is more likely to follow high earnings forecasts than low earnings forecasts. Finally, our analysis shows that shareholders may not find it optimal to prohibit earnings management. Earlier results rationalize earnings management by violating some assumption underlying the Revelation Principle. By contrast, in our model the principal can make full commitments and communication is unrestricted. Nonetheless, earnings management can be beneficial as it reduces the cost of eliciting truthful forecasts.     

Empirical Investigation of the Ability of Sensitivity of Stock Prices to Earnings News in Predicting Earnings Management and Management Forecast Errors

This paper presents an evidence that a firm’s Sensitivity of Stock Price to Earnings News (SSPEN), as measured by surplus stock demand over its supply, affects on incentives to manage earnings and, in turn, Management Forecast Errors (MFE). In particular, we find a tendency for firms rated a Sell (Buy) to engage more (less) frequently in extreme, income-decreasing Earnings Management (EM), indicating that they have relatively stronger (weaker) incentives to create accounting reserves especially in the form of earnings baths than other firms. In contrast, firms rated a Buy (Sell) are more (less) likely to engage in earnings management that leaves reported earnings equal to or slightly higher than management forecasts. The result of empirical evidence from Iranian firms in Tehran Stock Exchange (TSE) showing the existence of a meaningful relationship between SSPEN and EM. Generally, SSPEN can be used to predict EM and Forecast Errors (FEs).     

盈余管理真相

盈余管理是公司管理层实施战略管理的重要工具之一,合格的CF0并不一定必须去做盈余管理,但盈余管理却是CFO工作的重要组成部分。如果把盈余管理当作粉饰报表的工具,那就危险了。     

Real Earnings Management,Liquidity Risk and REITs SEO Dynamics

We analyze how REITs managers use real earnin gs management to address issues of liquidity risk and increased cost of capital they face during seasoned equity offerings. We show that REITs managers engage in real earnings management instead of accrual earnings management to attract more uninformed trading in order to provide the liquidity service at a lower cost during seasoned equity offerings. We find REITs with higher liquidity risk are more likely to manipulate earnings prior to equity offerings and uninformed trading is higher following real earnings management. Firms set the offer price at a smaller discount after engaging in real earnings management and stock returns decline in the long run. The findings are consistent with real option and liquidity risk explanations for equity offerings.     

The Inefficiency of the Mean Analyst Forecast as a Summary Forecast of Earnings

We show analytically that mean analyst forecasts inefficiently aggregate information by assigning too much weight to analysts' common information relative to their private information when used as a summary forecast measure of forthcoming earnings. A more precise summary forecast of earnings than the current mean forecast is the current mean forecast plus a positive multiple of the change in the mean forecast.     

上市公司信息披露质量与证券分析师盈利预测

本文研究了上市公司信息披露状况与分析师预测行为之间的关系，结果发现，分析师的预测准确性总体上显著优于随机游走模型。进一步的研究发现，上市公司信息披露状况会对证券分析师的预测特征产生影响，信息披露透明度越高，分析师预测对会计盈利数据的依赖程度越低，预测准确性也随之提高。     

The Effect of Earnings Management on the Asymmetric Timeliness of Earnings

Abstract:   Is earnings management affecting (driving) the measures of earnings conservatism? Ball et al. (2000) point out that the asymmetry in the recognition of good and bad news in earnings (faster recognition of bad news: earnings conservatism) is more pronounced in common‐law than in code‐law based accounting regimes. However, comparative studies on earnings conservatism in Europe have failed to identify significant differences between common‐law and code‐law based countries. We argue that in code‐law based countries managers have incentives to reduce earnings consistently. This enhances the association between earnings and returns in bad news periods. We find that after controlling for discretionary accruals, the differential earnings response to bad news in Germany and France decreases significantly.     

业绩预告披露与盈余管理研究

盈余管理存在的根本原因在于投资者与管理层之间的信息不对称。业绩预告作为上市公司未来经营成果、财务状况与现金流量的预测,在很大程度上会影响投资者对上市公司的评估及其投资决策。从业绩预告披露的特征方面出发,研究业绩预告披露与盈余管理之间的关系,包括业绩预告的性质、预告精确度、预告误差分别与盈余管理程度的关系,结果发现：发布业绩预告的公司,盈余管理水平更高。预告精确度以及预告期间与预测当期盈余管理水平正相关,预测误差与盈余管理水平负相关。当消息类型不同的时候,预测的强制性与否以及＂变脸＂对盈余管理水平的影响不同。结论支持了上市公司财务报告迎合业绩预告披露的说法。     

The Use of Unsigned Earnings Quality Measures in Tests of Earnings Management

This paper examines the implications of using the absolute value of discretionary accruals when testing for earnings management. First, we analytically develop the mean and variance of the distribution of absolute discretionary accruals, and show that the expected value is an increasing function of the variance in the underlying error term from the first‐stage discretionary accrual estimation model. Second, we highlight several firm characteristics that are related to the error variance in discretionary accrual estimation models. Using simulations, we show that correlation between the earnings management partitioning variable and these firm characteristics leads to an overrejection of the null hypothesis of no earnings management. Third, we provide research design suggestions to help researchers mitigate the potential bias arising from the use of unsigned measures of earnings management. Using these suggestions, we replicate a recent study, and demonstrate that the inferences change after controlling for operating volatility.     

Tests of Market Reaction and Analysts' Forecast Revisions to the Disclosure of Improved Management Earnings Expectations: A Case of Concurrent Bad News Management Earnings Forecasts

This paper tests whether a negative stock market reaction, associated with a management forecast of near term bad earnings, is lessened by a concurrent management forecast of improved longer term earnings expectations. Stock market reactions depend on the creditability of management forecasts of improved earnings expectations. In this analysis, the authors examined market reactions around the time of management forecasts of bad earnings, with and without longer-term management forecasts of improved earnings expectations. The results show that the stock market reaction is significantly less negative when management forecasts of bad earnings are followed by management forecasts of improved long run earnings expectations than when management forecasts of bad earnings are not accompanied by management forecasts of improved earnings expectations. In addition, this paper examines financial analysts' reactions to management bad earnings forecasts and management forecasts of improved earnings expectations. The findings show that analysts react less negatively to management forecasts of improved earnings expectations than to management forecasts of bad earnings. An analysis of a sub-sample of observations shows that analysts consider management forecasts of improved earnings expectations to imply improved expected future performance, thus conveying that analysts give credence to management forecasts of improved earnings expectations. However, results show that the stock market and analysts are unable to distinguish management forecasts of improved earnings expectations that come true from management forecasts of improved earning expectations that do not come true.     

Evidence That Management Earnings Forecasts Do Not Fully Incorporate Information in Prior Forecast Errors

Abstract:  This paper investigates whether managers fully incorporate the implications of their prior earnings forecast errors into their future earnings forecasts and, if not, whether this behavior is related to the post-earnings announcement drift. I find a positive association in consecutive management forecast errors, suggesting that managers underestimate the future implications of past earnings information when forecasting earnings. I also find that managers underestimate the information in their prior forecast errors to a greater extent when they make earnings forecasts with a longer horizon. Finally, I find that, similar to managers, the market also underreacts to earnings information in management forecast errors, which leads to predictable stock returns following earnings announcements.     

盈余管理的“度”

马靖昊：企业内部会计文化的缺失也助长了财务造假的风气目前盈余管理已成为众多上市公司为实现利益最大化所惯用的操作手法。虽然它的存在具有一定的合理性,但对众多上市公司而言,盈余管理质变后所带来的后果同样不可小觑。＂如果操作不当,质变后的盈余管理就是财务造假。＂畅捷通信息技术股份有限公司首席会计专家、中央财经大学研究生客座导师马靖昊在接受《新理财》专访时表示。操纵利润是企业盈余管理的普遍现象。在马靖昊看来,企业利润可以分为五种。     

The Relationship Between Unsystematic Security Returns and Earnings Forecast Errors*

This paper extends the Australian evidence on the information content of earnings announcements by considering both the sign and magnitude of unexpected earnings for a sample of 120 firms in the period 1964–1972, and a further 117 firms for 1972–1980. Results at both the portfolio level and the individual security level are highly significant and are consistent with those documented in both the United States and New Zealand.     

盈余管理策略

虽然盈余管理在西方国家已产生多年,但是对于盈余管理的定义,一直以来都没有一个统一的说法,威廉姆·R·斯科特认为,盈余管理就是在会计准则的许可权限之内,利用不同的会计政策,最大的实现企业的社会利益和经济利益;凯瑟琳？雪柏则认为,所谓的盈余管理指的就是企业的经营者对外界有选择性的公布企业信息,以达到企业利益的最大化。以笔者的观点来看,盈余管理就是在不违反相关的会计法规下,管理者的对会计收益报告进行操控。     

Investor Reaction to Celebrity Analysts: The Case of Earnings Forecast Revisions

We examine the effects of analysts' celebrity on investor reaction to earnings forecast revisions. We measure celebrity as the quantity of media coverage analysts receive in sources included in the Dow Jones Interactive database, and find that media coverage is positively related to investor reaction to forecast revisions. The effect of celebrity on the reaction to forecast revisions remains significant after controlling for forecast performance variables examined in prior studies (ex post forecast accuracy, ex ante accuracy, award status, and other variables shown to be related to forecast accuracy). While these results are consistent with the familiarity of the analyst's name affecting the market reaction, we cannot rule out that our measure of celebrity is correlated with error in the performance measures we examine and/or correlated with other unexamined dimensions of forecast performance. A content analysis of a random subsample of the media coverage of our sample analysts suggests that our findings likely are not due to the increased availability of forecast revisions. Finally, an investigation of the excess returns around the quarterly earnings announcement date suggests that market participants react too strongly to forecast revisions issued by analysts with high levels of media coverage. Taken together, these findings suggest that an analyst's level of media coverage can affect the initial market reaction to his forecast revisions.
