会计盈余、现金流量的价值相关性实证研究基于沪深股市的实证证据

已有的研究结果说明会计盈余具有价值相关性。从盈余等于经营现金流量与应计利润之和这一新的视角切入，以实证的方法对沪深两地上市的A股公司进行三大样本检验。并通过建立股票报酬与应计利润和现金流量的回归方程，利用应计利润回归系数的显著性对会计盈余与现金流量的价值相关性做比较，结果表明，会计盈余的价值相关性要大于现金流量的价值相关性。     

我国上市公司高送转公告效应的实证研究

为检验上市公司定高送转预案公告发布对其股票价格的影响,本文以2009年至2010年沪深两市推出高送转预案的285家上市公司为样本,选取公告日前10日至公告日后20日为事件窗口,运用事件研究法对高送转公告效应进行实证研究。结果表明：中国股市具有明显的高送转公告效应,上市公司高送转预案公告发布前后股票具有显著的正价格效应,会产生持续的累计异常正收益;然而,由于信息不对称,部分投资者通常会提前获得有关高送转的内幕信息并提前买入,并以此获得可观的超额收益,而普通投资在公告发布后买入只能获得小部分的超额收益并且需要承担更大的风险。     

货币政策、融资约束与现金股利

股利分配不仅是上市公司财务管理的核心内容,也是投资者获取回报的重要方式。以中国1999-2012年沪、深A股盈利上市公司为样本,本文检验了宏观货币政策和微观融资约束对公司现金股利发放的影响。研究发现:(1)紧缩的货币政策抑制了公司现金股利的发放;(2)公司面临的融资约束进一步强化了紧缩货币政策对现金股利的抑制作用;(3)银企关联有助于缓解紧缩货币政策对现金股利的抑制作用。进一步研究发现:出于再融资考虑,半强制分红政策的实施使得上市公司在货币政策紧缩期反而发放了更多的现金股利,体现出一定的政策导向作用。本文的发现不仅丰富了现金股利影响因素和货币政策经济后果的相关研究,同时也为我国股利监管政策的完善提供了一定启发。     

上市公司超能力派现与公司治理结构的实证研究

本文选取2003～2005年沪市和深市的1748家上市公司为样本,研究我国上市公司超能力派现与公司治理结构之间的关系.研究发现,第三大股东持股比例与超能力派现正相关,监事会规模、资产负债率和净资产收益率与超能力派现负相关.第一大股东持股比例与超能力正相关没有通过显著性检验,反映我国前几大股东可能合谋实现超能力派现.我国迫切需要优化公司治理结构争完善法制来制止超能力派现的发生.     

现金股利、控制权结构与股价崩溃风险

本文研究了上市公司在具有不同实际控股股东控制权结构下,现金股利与股价崩溃风险的关系。结果表明,过度支付现金股利会显著增加上市公司的股价崩溃风险;实际控制股东控制权与现金流权的分离程度会加剧现金股利与股价崩溃风险之间的正向关系。我们认为这一现象是现金股利中所蕴含的股东治理效应在资本市场上的体现。其现实意义在于,政策监管要着力于治“本”,通过提升公司治理水平以使股利分配真正立足于保护全体股东的利益。     

Earnings Yields,Market Values,and Stock Returns

Earlier evidence concerning the relation between stock returns and the effects of size and earnings to price ratio (E/P) is not clear-cut. This paper re-examines these two effects with (a) a substantially longer sample period, 1951–1986, (b) data that are reasonably free of survivor biases, (c) both portfolio and seemingly unrelated regression tests, and (d) an emphasis on the important differences between January and other months. Over the entire period, the earnings yield effect is significant in both January and the other eleven months. Conversely, the size effect is significantly negative only in January. We also find evidence of consistently high returns for firms of all sizes with negative earnings.     

Stock Price Volatility,Ordinary Dividends,and Other Cash Flows to Shareholders

This paper shows that the results of variance-bound tests depend on how cash distributions to shareholders are measured. As in prior studies, we find apparent evidence of excess volatility when a narrow definition of cash flow (dividends only) is applied. However, we are unable to reject the hypothesis of market efficiency when the cash flow measure also includes share repurchases and takeover distributions in addition to ordinary cash dividends.     

南橘北枳:A股市场的经济关联与股票回报

本文系统检验并比较了中国A股市场中行业动量、区域动量、供应链动量以及科技关联动量等经济关联动量的显著性及预测周期。本文发现,中国股票市场中经济关联因子呈现出与美国股票市场不同的规律,在月度层面行业动量显著,而科技关联因子只在周度上具有显著的预测能力。进一步分析科技关联动量发现,中国股票市场中科技关联因子能预测目标公司未来1-3周的股票收益和未来基本面的变化,据此构建的多空策略能够产生周度0.16%的超额收益(年化8.67%);机制检验发现,科技关联因子预测期短的原因是由于中国股票市场中存在较多具有博彩倾向的散户投资者;有限注意和市场摩擦两个机制检验证明科技关联动量源自错误定价。进一步检验发现,科技关联动量在国有企业和创新政策颁布后更加显著。本文补充了现有A股市场的动量研究,有助于理解中国股票市场规律、提升资本市场有效性。     

Earnings, Cash Flows and Security Returns Over Long Return Intervals: Analysis and UK Evidence

The aim of this paper is to provide a fuller understanding of the process linking security returns and accounting data by focusing on the effect of long return intervals on the association between security returns and earnings and cash flow variables. First, we develop a theoretical basis for empirical analysis of the relationship between security returns and cash flow data over long return intervals. Second, we carry out empirical analysis of both the information content of cash flow variables and the incremental information content of accounting earnings and cash flows using UK data over the period 1985–92 for annual, two year and four year return intervals. Our results provide strong evidence of the valuation relevance of cash flow information for the dataset examined.     

The persistence of current and proposed measures of operating cash flow

The measurement of operating cash flow using U.S. generally accepted accounting principles (GAAP) currently requires deductions for interest and income tax payments, and prohibits deductions for capital expenditures. In contrast, the IASB and the FASB are jointly proposing a new measure of operating cash flow which prohibits deductions for interest and income tax payments, and requires deductions for capital expenditures. This study compares the persistence of the current and proposed measures of operating cash flow, and the industry-specific results indicate that there is no significant difference between the persistence of the two measures for more than three-fourths of the industries in the sample. Moreover, the Boards’ constituents are recommending the use of a subtotal of operating cash flow prior to capital expenditures, and the results of this study suggest that this subtotal is more persistent for a limited number of industries than the current measure. Overall, the results of this study suggest that the predictive ability of operating cash flow will not change significantly for most industries.     

放松卖空管制与公司现金价值——基于中国资本市场的准自然实验

中国资本市场于2010年3月31日正式放开卖空管制,投资者可以对特定的股票进行卖空。放松卖空管制后,大股东如果继续侵占公司利益,投资者可通过卖空公司股票对大股东进行制衡。当卖空导致的股价下跌损失大于大股东侵占现金的收益时,现金资产被侵占的可能性降低,现金价值会有所提升。本文采用2007-2014年的中国上市公司为样本,借助放松卖空管制这一外生事件检验了这一问题,研究发现,放松卖空管制提高了公司的现金价值,并且这一影响主要体现在第一大股东持股比例较高的民营企业样本。     

Managerial Actions, Stock Returns, and Earnings: The Case of Business-to-Business Internet Firms

In this study we investigate the valuation implications of managerial actions undertaken by 57 Internet firms engaged in Business-to-Business (B2B) e-commerce. We classify 3,007 managerial actions undertaken by our sample firms between the firm's IPO date and September 30, 2000 into nine action categories: (1) acquisition of major customers, (2) introduction of new products and services, (3) promotional and marketing actions, (4) actions taken to address the concerns of stakeholders such as employees and the community at large, (5) announcements of technology, marketing, and distribution alliances, (6) completion of acquisitions, (7) expansion into international markets, (8) management team building actions, and (9) organizational changes.
In the short window tests, we find a significant increase in stock price volatility over a three-day event window surrounding the announcement of almost all actions suggesting that announcement of managerial actions provides value-relevant information to the stock market. In the long window tests, we use factor analysis to group the counts of managerial actions taken by each firm over its post-IPO life into two broad managerial initiatives—market penetration and organization building. These two initiatives explain a substantial portion of the cross-sectional variation in the firms' post-IPO life stock market returns beyond that explained by both reported earnings and analysts' forecasts of future earnings and revenues. Thus, investors appear to supplement relatively meager accounting information with data about the cross-sectional intensity of managerial actions in setting stock prices of B2B Internet firms.     

Dividend Policies and Price-Volume Reactions to Cash Dividends on the Stock Market: Evidence from the Istanbul Stock Exchange

This study examines the effects of cash dividend payments on stock returns and trading volumes in the stock market. It also investigates whether there is any difference in the investment behavior of investors with respect to the dividend pay out ratio and size in the Istanbul Stock Exchange (ISE)from 1995 to 2003. Prices start to rise a few sessions before cash dividend payments, and on the ex-dividend day, they fall less than do dividend payments, finally decreasing in the sessions following the payment. Trading volume shows a considerable upward shift before the payment date and, interestingly, is stable after Thus, cash dividends influence prices and trading volumes in different ways before, at, and after payment, providing some profitable active trading strategy opportunities around the ex-dividend day. The findings support price-volume reaction discussions on the divident payment date and the significant effect of cash dividends on the stock market.     

Order Flows and Stock Returns: Compensation for Market Makers with Inventory Concerns

We investigate whether market makers with inventory concerns are compensated with subsequent monthly returns in the cross‐section. We find a significant negative relation between order flows and monthly returns, “the order flow effect,” suggesting that market makers lower prices for stocks with sell order flows and demand a reward in the form of higher expected returns. Further, the order flow effect is stronger for high‐volatility or high‐volume stocks for which market makers have serious inventory concerns. Funding liquidity of market makers also affects the order flow effect. Finally, our finding is independent of existing regularities and robust to the decimalization.     

The Asset Pricing Palette: Cash Flows, Returns and Trading Behavior

Asset pricing is the topic of the 2001 Eastern Finance Association Symposium and the five papers selected for this collection, which are summarized below, span a broad range of subjects that fall under the umbrella of the determinants of market prices. For example, the Schwartz and Moon article that introduces the symposium uses real options methodology to value firms whose cash flows are subject to multiple sources of uncertainty while the Luders and Peisl and Mixon analytical models that close the selections incorporate dual stochastic processes to derive relationships between information flow, trading volume and price volatility that are consistent with empirical evidence. In between, Mishra and O'Brien present new evidence on the important of index and factor selection when estimating the required return on equity and Spahr and Schwebach revisit the issue of time diversification by reintroducing a statistical construct from earlier times. Each of the works included here makes an important contribution to our understanding of the asset pricing process in a distinct area and opens new doors onto avenues for future research.     

The Relationship between Earnings,Funds Flows and Cash Flows: Evidence for the UK

Recent UK information content studies have provided evidence of a significant relationship between earnings and share prices, as in the US, but have also identified an apparent lack of information content for operating cash flow, which is in marked contrast to findings from US research. This paper provides direct evidence on the relationship between earnings, funds flows and cash flows in the UK during the period 1965–84, using tests of association and predictive tests based on a research methodology applied by Bowen, Burgstahler and Daley (1986) to US data. The results provide UK evidence on the contemporaneous and predictive relationships between measures of earnings, funds flows and cash flows which are generally consistent with the US findings of Bowen et al. and which do not support the view that earnings in the UK are superior to cash flows as predictors of future cash flows.     

现金股利政策与企业生命周期——基于中国上市公司的实证研究

以中国2006～2010年A股上市公司为样本,基于企业生命周期考量公司现金股利政策与企业生命周期之间的关系。结果表明:中国上市公司生命周期不同阶段现金股利政策具有显著的差异,公司盈利能力是形成企业不同生命周期阶段现金股利政策差异的显著原因。企业不同生命周期公司治理结构差别不大,在不同生命周期阶段对企业现金股利政策的影响在不同生命周期阶段也大同小异。
