上市公司信息披露能够为投资者提供更多前瞻性信息,是投资者进行决策的重要信息来源。证券分析师作为资本市场的信息中介,对缓解信息不对称具有重要的作用。为厘清上市公司前瞻性信息披露能否影响分析师盈余预测的准确度,以2007—2020年A股上市公司为样本,研究前瞻性信息披露对分析师盈余预测准确度的影响。研究结果显示,上市公司前瞻性信息能够显著提高分析师盈余预测准确度。进一步研究发现,融资约束低、机构持股比例高、年报可读性高和股价同步性高的上市公司,前瞻性信息披露对分析师盈余预测准确度的提升效果更为明显。研究结论从前瞻性信息的信息含量视角丰富了分析师盈余预测准确度的相关研究,为全面注册制背景下进一步健全资本市场信息披露制度提供了政策参考。  相似文献

盈余预告研究一直是学者们关注的重点领域,其披露规律也是学术界重要谜团之一。本文提出影响盈余预告披露的新机制——股市的波动性,并借此为特有的研究场景来观测管理层择时披露行为。本文以2003-2015年管理层盈余预告披露的上市公司为样本,实证检验上市公司管理层是否会利用股票市场的高频波动来选择盈余预告信息披露的时机及该策略的实施效果。研究发现:公司管理层盈余预告披露决策会隐性观察市场的波动态势及其幅度,基于披露法定的时滞裁量空间,利用短期市场行情波动性选择较优的披露时机。具体体现在管理层倾向选择市场行情上升期披露更多坏消息,在市场行情下降期披露更多好消息;与不使用该策略的公司相比,使用该策略的公司能获得更好市场反应。  相似文献

上市公司季度盈余信息含量的实证研究   总被引:3,自引:0,他引:3  
盈余的信息含量可以通过股票报酬率(股价变动)与盈余之间的相关性来评价.采用此方法的逻辑基础是:如果一条消息能够导致信息接受者所关心的随机变量可能分布的变化,那么这条消息就传递了信息.在国外,盈余的信息含量研究最早始于本斯顿(Benston,1966)以及鲍尔和布朗(Balland Brown,1968),他们通过探讨证券价格变动与盈余变动之间显著关联来检验盈余的信息含量.在我国,较早运用会计盈余与股票价格关系方面做实证研究的是赵宇龙博士.1998年,他借鉴Ball和Brown(1968)的研究方法,对上海股市123家样本公司1994~1996年年报的信息含量进行了检验.1999年陈晓、陈小悦和刘钊对1994~1997年上海和深圳两家交易所上市公司的盈余披露进行了检验;陆宇峰(1999)对1993~1997年年度盈余的信息含量进行了检验.2003年,郭菁对1999~2001年的中期报告的信息含量进行了研究.  相似文献

本文基于2012-2019年沪深A股上市公司的研究样本,实证检验了公司披露其客户名称对投资者的影响。本文利用长期盈余反应系数度量投资者对风险的感知,分析自愿性信息披露的利弊。结果发现:公司在年报中同时披露前五大客户名称以及明细金额,相比于只披露了明细金额的公司,有显著更低的长期盈余反应系数;异质性检验发现,当公司的专有成本更高、投资者专业能力更强或者市场交易风险更高时,会加剧这种负向关系;经济后果检验发现,披露客户名称后,公司下期的市场表现、经营业绩以及盈余持续性都显著更差。由于专有成本的存在,客户名称的披露会增强投资者对公司未来经营风险的感知,投资者能够理性预期到上市公司披露客户名称并非完全有益。鉴于客户、特别是大客户对公司的重要影响,本文的研究结论有助于分析目前客户信息披露规定的政策效果,也为后续制定相关披露政策提供了依据。  相似文献

提高信息披露质量对于改善上市公司治理结构和保护股东权益具有重要意义。本文利用2014年开通的“沪港通”机制这一准自然实验,研究资本市场开放是否提高了企业的信息披露质量。从2010-2019年A股上市公司年报文本中提炼可读性指标衡量信息披露质量,使用匹配和双重差分方法进行实证研究,发现“沪港通”机制实施以后,标的公司(纳入“沪港通”的A股上市公司)的信息披露质量显著提高。这一结论对不同的估计方法、样本区间及控制变量组均保持稳健。异质性分析表明,对于盈余操纵水平较高、股价信息含量较低的企业,资本市场开放能够更好地改善其信息披露质量。本文丰富了资本市场开放对企业行为和绩效影响的实证研究,为继续推进资本市场开放政策提供了理论依据。  相似文献

We examine the reaction of the equity options market to accounting earnings announcements over the period 1996–2008 using changes in implied volatility to measure the options market response to earnings news. We find that positive earnings surprises and positive profit announcements produce a larger uncertainty resolution than negative earnings surprises and loss announcements. We demonstrate an inverse relation between the change in implied volatility and earnings news in a three-day window immediately after an earnings announcement. We refer to the magnitude of this relation as the ‘options market earnings response coefficient’. This ‘options market earnings response coefficient’ is stronger for both bad news announcements and positive profit announcements. We do not find any significant relation between changes in implied volatility and earnings news in the pre- or post-announcement periods. We conclude that the options market efficiently absorbs earnings information.  相似文献

We quantify the relative importance of earnings announcements in providing new information to the share market, using the R2 in a regression of securities' calendar‐year returns on their four quarterly earnings‐announcement “window” returns. The R2, which averages approximately 5% to 9%, measures the proportion of total information incorporated in share prices annually that is associated with earnings announcements. We conclude that the average quarterly announcement is associated with approximately 1% to 2% of total annual information, thus providing a modest but not overwhelming amount of incremental information to the market. The results are consistent with the view that the primary economic role of reported earnings is not to provide timely new information to the share market. By inference, that role lies elsewhere, for example, in settling debt and compensation contracts and in disciplining prior information, including more timely managerial disclosures of information originating in the firm's accounting system. The relative informativeness of earnings announcements is a concave function of size. Increased information during earnings‐announcement windows in recent years is due only in part to increased concurrent releases of management forecasts. There is no evidence of abnormal information arrival in the weeks surrounding earnings announcements. Substantial information is released in management forecasts and in analyst forecast revisions prior (but not subsequent) to earnings announcements.  相似文献

机构投资者持股与会计盈余宣告的信息含量   总被引:1,自引:0,他引:1  
本文以我国2001—2004年机构投资者持股的上市公司为样本,从机构投资者对上市公司信息利用状况的视角出发,分析了机构投资者持股与会计盈余宣告信息含量的关系,研究结果发现:机构投资者能够相对较早地解读会计盈余信息,其持股比例越高,盈余宣告后的市场反应越小.会计盈余宣告的信息含量越低。在会计盈余宣告前,机构投资者的持股比例高低与市场的累计超额回报正相关;而在盈余宣告后,机构投资者待股公司的市场累计超额回报出现反转。  相似文献

Do IFRS Reconciliations Convey Information? The Effect of Debt Contracting   总被引:1,自引:0,他引:1  
We examine whether earnings reconciliation from U.K. generally accepted accounting principles (GAAP) to International Financial Reporting Standards (IFRS) convey information. As a result of debt contracting, mandatory accounting changes are expected to affect the likelihood of violating existing covenants based on rolling GAAP, leading to a redistribution of wealth between shareholders and lenders. Consistent with this prediction, we find significant market reactions to IFRS reconciliation announcements. These market reactions are more pronounced among firms that face a greater likelihood and costs of covenant violation and early announcements. While the association between later announcements and weaker market reactions is consistent with contractual implications of technical changes to earnings, which investors quickly learn to predict, it is inconsistent with IFRS forcing all firms in the sample to reveal firm-specific information through accruals. Thus, by showing that mandatory IFRS also affects debt contracting, we expand on existing IFRS research that focuses on how accounting quality and cost of capital are impacted.  相似文献

Several recent studies have used U.S. analysts' forecasts to test for underreaction or overreaction to information in earnings announcements. These tests have provided mixed results. Evidence in Mendenhall (1991) is that analysts underreact. By contrast. results in De Bondt and Thaler (1990) show overreaction by U.S. financial analysts to earnings announcements. The current study contributes to this topic by examining over/underreaction by Japanese financial analysts. Test results show that Japanese analysts do not overreact to earnings announcements, market to book ratios and sales growth. Instead. there is strong evidence that Japanese analysts underreact to earnings announcements and that their underreaction is more pronounced for firms with mostly permanent earnings. Our results also show that Japanese analysts display larger forecast biases for earnings reported under U.S. GAAP as opposed to Japanese GAAP. Finally, we find that US. analysts discount information in earnings announcements to a larger degree (relying to a greater extent on information in past prices instead) when compared to their Japanese counterparts. Further, in contrast to their Japanese counterparts, these analysts display no optimistic bias. The results above suggest that the impact of each country's unique culture and capital norms will have to be taken into account by policy makers in evaluating the feasibility of harmonization of accounting standards.  相似文献

Previous studies have interpreted stock price reaction to dividend announcements as being consistent with the hypothesis that any changes are forecasts of future corporate profits. Recent studies seem to provide evidence to this effect. This study provides additional empirical evidence pertaining to the issue of whether quarterly cash dividend announcements convey useful information about a firm's future profitability, beyond that contained in contemporaneous quarterly earnings announcements. The association between unexpected changes in quarterly dividends and unexpected accounting earnings in subsequent quarters is examined, after controlling for information contained in past and current earnings series. The results, based on a large sample of regular quarterly cash dividend changes, indicate that firms that increased (decreased) their dividends realized, on average, greater (smaller) unexpected accounting earnings in subsequent periods than firms that did not change their dividends.  相似文献

Information Asymmetry Around Earnings Announcements   总被引:1,自引:1,他引:0  
This study examines bid-ask spreads to determine how the anticipation and release of earnings announcements affect information asymmetry in the stock market. I use regression analysis and find that bid-ask spreads are negatively related to public information availability and positively related to earnings variability and the market reaction to prior unexpected earnings. The results suggest that firms for which earnings is expected to yield a relatively larger stock market reaction have greater information asymmetry than firms for which earnings are expected to yield a smaller market reaction.I also find that bid-ask spreads gradually increase in the four days prior to earnings announcements, and increase sharply the day prior to, the day of and the day after the earnings announcements. Bid-ask spreads seven to ten days after earnings announcements are not significantly different from bid-ask spreads seven to ten days prior to earnings announcements.  相似文献

We compute abnormal return variance and abnormal trading volume in the 3‐day window surrounding earnings announcements to examine the information content of earnings announcements in the New Zealand equity market over the past 16 years. We find that the information content of earnings announcements has increased significantly over time, and this finding holds true for both interim and preliminary earnings announcements. We find evidence that earnings announcements with June year‐ends exhibit a higher level of information content and experience a more pronounced rising trend as compared to earnings announcements with non‐June year‐ends. Several firm characteristics appear to relate to the level of the information content of earnings announcements as well as to compound the trend over time. We document an important finding that the information content of earnings announcements increases remarkably in the period after the adoption of the International Financial Reporting Standards (IFRS).  相似文献

Motivated by the availability of high-frequency data on trading activity, this paper proposes the use of order aggressiveness as a metric to evaluate the usefulness of accounting information. I test, through an analysis of order aggressiveness, whether earnings announcements of firms listed on the Italian Stock Exchange limit order book have information content. I estimate an ordered probit relating order aggressiveness to unexpected earnings and to three market determinants of aggressiveness. Consistent with the theory on the choice between limit and market orders, I find that order aggressiveness increases with the absolute value of unexpected earnings. The results provide evidence on the extent to which the information contained in earnings is used by traders.  相似文献
