我国证券分析师预测代表市场预期的能力提高了吗?来自年报信息市场反应检验的证据

本文以集中发布了分析师行为规范的2005年为转折点,参考对比随机模型和管理层预测,在年报公布后的长窗口内检验分析师的盈利预测代表投资者盈利预期的能力是否有所提高。结果表明,在2005年之后,伴随着分析师预测准确度的提高,其代表市场预期的能力也有所提高,这从投资者认同的角度揭示了我国分析师行业的逐步规范和发展。本文的发现还表明,相对于管理层预测和随机模型的预测而言,分析师预测可能是更合适的市场预期替代变量。     

分析师特征券商规模与盈利预测

本文选取2002-2008年国泰安分析师预测数据,考察分析师特征对盈利预测误差的影响.研究发现,分析9币预测经验、券商规模、努力程度与其预测误差呈显著负相关;任务难度与其预测误差显著正相关.进一步的研究显示,分析师个人特征以及券商规模对其盈利预测误差的影响在盈利公司和亏损公司之间存在着非对称性,男女性别的差异也导致分析师个人特征在影响盈利预测准确度上存在着系统性差异.本文的研究结论为公众投资者判断分析师预测能力提供了必要的经验证据和决策支持.     

基本面、资金面对中国股市波动影响分析

本文以2002年6月至2010年7月国泰安中国上市公司分析师预测研究数据库分析师对上市公司的盈利预测,并以Wind数据库中国债交易和货币发行数据为基础,通过建立行业面板模型,分析基本面变动和资金面变动在中国股票市场价格波动中所起到的作用。研究结果显示,资金变动是影响股票市场波动最主要的因素。     

《新财富》评选的最佳分析师可信吗?——基于盈利预测准确度和预测修正市场反应的经验证据

本文利用2005-2008年的分析师盈利预测的数据,从盈利预测的准确性和预测修正的市场反应两个维度,对比分析了《新财富》杂志评选的最佳分析师与其他分析师的盈利预测能力。研究发现,最佳分析师盈利预测的准确性比其他分析师高;最佳分析师预测修正的勇敢程度略高于其他分析师;当预测修正程度大于90%时,最佳分析师预测修正的市场反应高于其他分析师预测修正的市场反应。研究结果表明,总体来说新财富最佳分析师的预测能力强于其他分析师,投资者在一定程度上可以信赖新财富最佳分析师。     

名义价格幻觉——基于证券分析师目标价格预测的经验证据

本文利用证券分析师发布的股票目标价格预测,为名义价格幻觉提供了能够直接反映心理预期的经验证据。研究发现,证券分析师对低价股未来收益的心理预期显著高于高价股,该行为偏误在规模小、上市时间短、股票波动性大、财务透明度低和无形资产占比高等估值难度更大的股票中表现得更加明显。我们还利用股票送转,对证券分析师是否受到名义价格幻觉的影响做进一步验证,发现由送转引起的与基本面无关的名义价格下降显著提升了证券分析师对股票未来回报的心理预期。进一步研究表明,上述发现并不是因为证券分析师准确预见了低价股和高价股未来有不同的投资机会,也不是为了最大化其供职证券公司的利益而有意迎合投资者。     

投资者情绪、期权隐含信息与股市波动率预测——基于上证50ETF期权的经验研究

在异质自回归模型(HAR-RV)中引入中国上证50ETF期权隐含信息和投资者情绪,本文分别对中国股票市场未来日、周和月波动率进行预测。研究发现,期权隐含信息和投资者情绪能够提高HAR-RV模型对股票市场未来波动率的预测效果。投资者情绪对未来波动率的影响存在两种机制:在情绪高涨期间,月已实现波动率与未来波动率正相关,说明以个人投资者占主体所引起的价格信息机制,在中国股票市场交易中占主导作用;风险中性偏度与未来波动率负相关,说明以个人投资者占主体所引起的噪声交易机制占主导作用。     

分析师对创新相关信息的关注能提高预测准确性吗？

本文通过对2012―2020年分析师发布的研究报告进行文本分析，提取其中的创新相关信息含量，探究分析师的创新相关信息关注对于提高其盈利预测准确性的价值。研究发现，分析师研究报告中创新相关信息的含量与盈利预测准确性正相关，说明分析师对创新相关信息的关注有助于提高其盈利预测质量；特别是在公司创新活动强度较大、盈余质量较差、信息不对称程度较高的情况下，分析师对创新相关信息的关注和利用对于提高其盈利预测准确性的作用更强。本文丰富了关于分析师盈利预测和非财务信息价值的研究，为分析师的信息关注和利用提供了一定的启示。     

证券分析师的信息解读能力调查

本文是对我国证券分析师1994-2003年1156份“年报分析”的调查。我们发现,总体上看,证券分析师对年报信息的使用能力在提高,对管理信息和会计信息的使用频率都有所上升,且会计信息的使用比例远高于管理信息。但是,在会计信息中,对盈利能力特别关注。此外,证券分析师使用的财务分析工具和方法一般还只停留在常用比率分析上。在这类分析报告中,很少有预测分析。可以说,预测分析是我国证券分析中最为薄弱的地方之一,也很少有分析师根据分析结果给出具体的买卖建议。     

董事会报告可读性、制度环境与分析师预测——来自我国上市公司的经验证据

依据2007-2016年中国上市公司数据,考量上市公司董事会报告可读性、制度环境对证券分析师盈利预测表现的影响。结果发现：董事会报告可读性越好,分析师预测越准确,分析师预测的分歧度也越小;考虑宏观制度环境的影响,上市公司所处地区的制度环境越好,分析师盈利预测的准确度越高,分歧度越小,受到董事会报告可读性的影响越少。鉴此,应完善公司非财务信息披露和外部制度环境,从而提高分析师预测准确性,促进资源有效配置。     

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。     

剩余收益模型与股票未来回报

本文采用Hou et al.(2012)公司基本面盈余预测模型并结合剩余收益模型对上市公司的内在价值进行估计,并分析内在价值与市价比率(V/P)与股票未来回报之间的关系。我们发现基于V/P分组的投资组合,在未来一至三年规模调整的持有超额回报套利分别达到15.2%、37.9%和55.9%;在控制了市账比等因素以后,V/P对股票未来回报仍然具有显著的预测作用。本文的研究克服了以往文献中运用证券分析师盈余预测进行剩余收益模型估值的内在局限,并提供了我国资本市场背景下切实可行的基于剩余收益模型估值的投资组合策略。     

Investor and (Value Line) Analyst Underreaction to Information about Future Earnings: The Corrective Role of Non-Earnings-Surprise Information

Prior research suggests that financial analysts' earnings forecasts and stock prices underreact to earnings news. This paper provides evidence that analysts and investors correct this underreaction in response to the next earnings announcement and to other (non-earnings-surprise) information available between earnings announcements. Our evidence also suggests that analysts and investors underreact to information reflected in analysts' earnings forecast revisions and that non-earnings-surprise information helps correct this underreaction as well. Controlling for corrective non-earnings-surprise information significantly increases estimates of the degree to which analysts' forecasting behavior can explain drifts in returns following both earnings announcements and analysts' earnings forecast revisions.     

证券分析师VS统计模型:证券分析师盈余预测的相对准确性及其决定因素

本文使用2005年35家券商对我国上市公司做出的每股盈余预测数据,考察了证券分析师盈余预测相对于统计模型的相对准确性及其决定因素。我们发现,我国证券分析师做出的盈余预测,同以年度历史数据为基础的统计模型得出的盈余预测相比,预测误差较小,证券分析师盈余预测具有一定的优势;但同某些以季度历史数据为基础的统计模型得出的盈余预测相比,预测误差较大,证券分析师盈余预测不具有优势。我们同时考察了决定证券分析师盈余预测相对准确性的决定因素。我们发现,公司每股盈余的波动性越大,公司上市越晚,跟踪公司的分析师越多,证券分析师的优势就越大。我们的研究对证券分析师以及投资者都有一定的启示作用。     

Stock price reactions to earnings announcements: evidence from Chinese markets

We examine the stock price reactions to changes in earnings per share (EPS) in the Chinese stock markets. We find that domestic A-share investors do not correctly anticipate the changes in earnings and fail to adjust new earnngs information quickly, but international B-share investors can predict earnings changes better than A-share investors. As a result, abnormal returns (ARs) can be obtained by trading on the earnings information, but for A shares only. An explanation is that most A-share holders are individuals with short-term investment horizon while most B-share holders are large institutions that trade on more detailed and accurate financial information not immediately available to A-share holders.     

The information content of financial analysts' forecasts of earnings: Some evidence on semi-strong inefficiency

The paper assesses the information content of revisions in financial analysts' forecasts of earnings by analyzing the relation between the direction of these revisions and stock price behavior. Abnormal returns during the months surrounding the revisions in analysts' forecasts are computed and evaluated. The results strongly indicate that information on revisions in forecasts of earnings per share is valuable to investors. It is also suggested that market reaction to the disclosure of analysts' forecasts is relatively slow and gives rise to potential abnormal returns to investors who act upon this type of publicly available information.     

The effect of changes in Japanese consolidation policy on analyst forecast error

Our broad research objective is to investigate whether convergence towards international standards improves the decision usefulness of information. Recent changes in Japanese consolidated reporting practices to better align with international standards provide an excellent setting to investigate this research objective. Specifically, we examine the effect of changes in Japanese consolidation policy on financial analysts’ perceptions of the persistence of subsidiary earnings. Previous research provides evidence that, prior to the change in consolidation policy, consolidated financial information was not used efficiently in the Japanese capital market. Prior research finds a positive relation between subsidiary earnings and future stock returns in Japan, indicating that investors underestimate the persistence of subsidiary earnings. Consistent with prior research using stock returns, we find that financial analysts also underestimate the persistence of subsidiary earnings in Japan. We document a significant positive relation between subsidiary earnings and future forecast errors of consolidated earnings. However, following the changes in consolidation policy in Japan, we find that financial analysts no longer underestimate the persistence of subsidiary earnings. Changes in Japanese consolidation policy in conformance with international standards increase decision usefulness by improving the ability of financial analysts to predict overall firm performance. One limitation of our research design relates to the adoption of mandated accounting policy changes by all sample firms in the same calendar time. This makes it difficult to control for the impact of correlated omitted variables. While this concern can never be completely eliminated, we provide additional tests that examine sample partitions by firm size and industry. These additional tests support the primary findings that Japan’s efforts to converge consolidation rules with international standards have improved analysts’ consolidated earnings forecasts.     

Earnings Forecasts and the Information Contained in Spinoff Announcements

This study examines spinoff announcements in conjunction with financial analysts’ forecasts of earnings. The analysis shows that spinoff announcement abnormal returns are significantly related to the firm's information environment as proxieci by financial analysts’ earnings prediction errors. The findings also indicate that analysts significantly increase their short-term earnings forecasts in response to spinoffs, but do not significantly revise their long-term earnings forecasts. However, the earnings revisions are not significantly different across prediction error groups, which confirms that spinoff-related abnormal returns cannot be attributed solely to expected performance gains.     

Risk,Mispricing, and Value Investing

We evaluate the stock return performance of a modified version of the book-to-market strategy and its implications for market efficiency. If the previously documented superior stock return of the book-to-market strategy represents mispricing, its performance should be improved by excluding fairly valued firms with extreme book-to-market ratios. To attain this, we classify stocks as value or glamour on book-to-market ratios and accounting accruals jointly. This joint classification is likely to exclude stocks with extreme book-to-market ratios due to mismeasured accounting book values reflecting limitations underlying the accounting system. Using both 12-month buy-and-hold returns and earnings announcement returns, our results show that this joint classification generates substantially higher portfolio returns in the post-portfolio-formation year than the book-to-market classification alone with no evidence of increased risk. In addition, this superior stock return performance is more pronounced among firms held primarily by small (unsophisticated) investors and followed less closely by market participants (stock price <$10). Finally, and most importantly, financial analysts are overly optimistic (pessimistic) about earnings of glamour (value) stock, and for a subset of firms identified as overvalued by our strategy, the earnings announcement raw return, as well as abnormal return, is negative. These last results are particularly important because it is hard to envision a model consistent with rational investors holding risky stocks with predictable negative raw returns for a long period of time rather than holding fT-bills and with financial analysts systematically overestimating the earnings of these stocks while underestimating earnings of stocks that outperform the stock market.     

Investor and Analyst Reactions to Earnings Announcements of Related Firms: An Empirical Analysis

In this article I examine the response of investors and analysts of nonannouncing firms to the earnings report of the first announcers in the industry. The error in the earnings forecast of the first announcer is found to be informative about the errors in the contemporaneous earnings forecasts of subsequent announcers in the industry. However, investors and analysts do not appear to fully incorporate the information from the first announcers' news in their revised earnings expectations for subsequent announcers. This apparent underreaction to the first announcers' news leads to predictable stock returns for subsequent announcers in the days following the first announcement. Results of this study can be seen as further evidence of investor and analyst underreaction to publicly available information.     

线上销售与未来股票收益

本文通过分析相关上市公司在电商平台的线上销售数据,发现线上销售增长可以预测未来股票收益。根据线上销售增长率构建投资组合可以获得月均1.27%的超额收益,经三因子、五因子模型调整后收益率分别为1.40%和1.35%,并且该超额收益在较长时间内不会逆转。横截面回归结果显示,线上销售增长与未来股票收益显著正相关,并在控制其他市场异象因子后仍然显著。此外,本文还发现线上销售数据的预测能力主要集中在投资者关注有限、线上销售占比高以及套利成本高的公司,其投资价值来源于对公司未来基本面信息的预测能力。进一步研究表明,同时利用线上销售指标和营业收入指标进行投资可以获得更高的超额收益。在考虑业绩预告和业绩快报对线上销售指标预测能力的潜在影响后,结果依然稳健。
