反收购条款、机构投资者与股价信息含量

文章采用2008—2016年A股上市公司数据,研究反收购条款如何通过机构投资者的持有渠道和交易渠道影响公司股价信息含量。实证结果表明,反收购条款会降低机构投资者的持有比例和交易比例,进而降低股价信息含量。将机构投资者分为稳定型和交易型后发现,反收购条款对稳定型机构投资者的影响主要体现在持有渠道,对交易型机构投资者的影响主要体现在交易渠道。进一步分组检验发现,在股权集中度低的公司、民营公司及法律环境差的地区,反收购条款的上述作用更大。

会计稳健性、机构投资者异质性与股价崩盘风险——来自中国A股上市公司的经验证据

股价崩盘风险已经对资本市场的健康发展产生了重要影响。以中国资本市场2008年至2013年A股上市公司为样本,实证检验了会计稳健性与股价崩盘风险的关系,并考察机构投资者异质性对二者关系的影响。研究结果表明,会计稳健性能够显著降低股价崩盘风险。进一步考察机构投资者异质性,在划分为稳定型与交易型的基础上,发现稳定型机构投资者会增强二者的负向关系,交易型机构投资者则削弱二者的负向程度。文章的研究结论为防范股价崩盘风险、构建平稳有序的资本市场提供了一定的借鉴意义。     

我国资本市场投资者利益保护与上市公司价值研究

一个国家的法律对投资者利益保护程度会因其法律起源不同而不同,进而影响到证券市场的发展质量.上市公司作为证券市场的主体,被市场赋予的市场价值是衡量公司增长潜力和投资者信心的重要指标.本文对我国中小投资者利益保护与上市公司价值进行了实证检验.结果表明,法律对中小投资者利益保护程度与公司价值的正向作用显著,也就是说,在中国资本市场和法律保护发展的历史进程中,随着法律保护程度的加强,上市公司的价值也在不断提高.     

上市公司关联交易与盈余管理关系实证研究——基于沪市A股上市公司面板数据

本文选取2009年至2011年我国沪市A股上市公司作为研究样本,对上市公司是否普遍采用关联交易作为盈余管理手段、不同公司特征下关联交易与盈余管理的关系进行了实证检验。研究发现：关联交易与盈余管理程度正相关。在不同的公司特征下关联交易与盈余管理的关系,被ST上市公司较未被ST上市公司、有再融资计划的上市公司较没有再融资计划的上市公司、第一大股东处于绝对控股地位的上市公司较第一大股东不处于绝对控股地位的上市公司均会强化通过关联交易进行盈余管理的动机。     

机构投资者本土偏好与上市公司会计信息质量

本文基于信息成本理论,以2008~2011年沪市A股上市公司为研究对象,实证检验了机构投资者本土偏好对上市公司会计信息质量的影响。结果表明:随着上市公司注册地与机构投资者所在地之间的地缘联系减少,上市公司会计信息质量随之下降,并且这一效应只在上市公司位于非一线城市的情况下存在;机构投资者持股比例的增加,显著削弱了地缘联系和上市公司会计信息质量之间的负相关关系,说明机构投资者持股比例较高的时候,将会加强对上市公司的监督,使得地缘联系对上市公司会计信息质量的影响减弱,从而降低了不同远近距离的投资者间的信息不对称,减轻了"本土偏好"程度。     

基于KMV模型的信贷违约风险探析

本文采用KMV模型,结合相关的财务特征指标,对我国上市公司的信用状况进行实证检验.检验结果表明,KMV模型能在上市公司财务困境发生前三年对上市公司的违约风险进行预警,在我国具有较好的适用性.根据实证检验结果,提出将不同预警模型相结合,层次递进建立我国信贷风险预警机制的建议.     

大数据时代股权结构对公司绩效的影响——基于股权集中度和机构投资者视角

股权结构与公司绩效之间的关系一直是国内外学者研究的热点话题,结论的不一致使得两者的关系始终保持着研究价值。文章基于委托代理理论和股东积极理论,以2008—2012年沪深两市上市公司大数据为样本,鉴于可能存在内生性问题,采用随机效应面板模型,就股权集中度、机构投资者持股对公司绩效的影响进行了实证研究,并进行了稳健性检验。研究结果发现,股权集中度与上市公司业绩呈倒U型关系,机构投资者的持股比例能够显著提升上市公司的绩效。     

公司精准扶贫信息披露与股权融资成本的实证研究

我国上市公司广泛深入地参与了扶贫活动.2016年颁布的《关于完善上市公司履行扶贫社会责任信息披露的通知》对上市公司扶贫的信息披露做出了规范.那么披露的扶贫信息将给公司带来什么经济后果呢?本文以2016—2020年A股上市公司为研究样本,实证分析了扶贫信息披露对上市公司股权融资成本的影响.研究结论表明:上市公司扶贫信息披露能显著降低股权融资成本;中介效应检验发现,上市公司精准扶贫信息披露会使投资者信息不对称程度及监督成本下降,从而降低上市公司股权融资成本.因此,对上市公司来说,在积极参与扶贫公益活动的同时,还要积极"说出来".     

投资者偏好与公司股利政策的实证研究

文章就我国投资者对上市公司股利政策的偏好与公司股利分配政策进行了实证研究.研究表明,市场投资者普遍喜好股票股利和混合股利,对现金股利反应较为冷淡;上市公司的股利政策以股票股利和混合股利为主.在此实证研究的基础上,文章运用行为金融理论对投资者偏好和上市公司的股利分配政策分别进行了分析.     

转型期我国股票市场规制目标的选择

"为国有企业筹资、推动国民经济增长"这一政府股票市场规制的目标已经不能适应经济发展的要求,监管当局应该将"加强投资者利益保护"作为股票市场规制的核心目标,以进一步推进中国股票市场的可持续发展。保护投资者利益是股票市场政府规制目标的核心。造成我国股票市场投资者保护机制缺失的制度性基础在于政府一身兼三职的制度安排,即政府既是国有上市公司、证券交易所、证券公司的实际或者变相的终极所有者,又是投资者利益的守护神,同时也是证券市场的规制与监管者。     

Investor relations on the Internet: a survey of the Euronext zone

This study investigates the investor relations activities on the Internet of companies listed on the Euronext stock exchange. For this purpose, the websites of the fifty largest listed companies in each of the countries Belgium, France and the Netherlands were screened for investor relations items. Results obtained by using a three-stage model show that most companies in the Euronext zone are at the second stage of Internet investor relations, i.e. where information available through other sources is combined to better inform investors. In the third stage companies use the full interactive possibilities of the Internet for investor relations purposes. French and Dutch companies use the Internet for investor relations purposes more widely and more intensely than Belgian companies. The study also revealed a size effect; large companies use the Internet for investor relations purposes more extensively than smaller companies. This conclusion holds for each of the three countries. The leading companies in France and the Netherlands are either at the third stage of Internet investor relations or are ready to move to this stage.     

投资者情绪、股利政策与公司价值研究

基于行为金融学背景对股利政策的信号传递作用进行的研究发现,在不同的投资者情绪条件下,股利政策信号传递的效应存在差异。在股市上涨时期,不同股利政策对投资者的投资决策的影响几乎没有显著差异;在股市下跌时期,现金股利成为投资者获得收益的主要来源,因此发放现金股利的公司受到市场追捧。因此,上市公司股利政策制定不仅要考虑自身情况,还需要考虑市场情绪。     

Disagreements with noisy signals and asset pricing

We consider a Lucas-type exchange economy with two trees and two investors to analyze the effects of heterogeneous beliefs and signal quality on stock market equilibrium. Our model has the following implications. There are spillover effects, in that the investors’ heterogeneous beliefs and signal quality related to one stock not only affect its own price and pricing moments, but also affect those of the other. Contrary to the conventional wisdom, we show that the volatility of one stock decreases with both its own and the other stock’s disagreements. Additionally, we reveal a negative correlation between the stocks, which decreases as the investors’ dispersions raise but increases as the discrepancy in signal quality reduces. We also show that heterogeneous beliefs and signal quality impact stock market beta mainly through scale and volatility effects, respectively. Furthermore, our findings suggest that both heterogeneous beliefs and signal quality have significant influences on the investors’ optimal portfolio plans.     

股票价格低于每股净资产的影响因素分析——来自中国A股上市公司的经验证据

破净指股票价格跌破每股净资产,是股票价格与每股净资产关系的一种极端表现。本文以1 059家A股上市公司为样本,采用修正的Ohlson模型,分组对股价破净的影响因素进行研究。结果发现:对于业绩为正的非ST企业而言,公司规模大、上市时间早、机构投资者持股比例低的国有企业容易破净;ST企业的股票价格虽下跌,但其重组捷径和壳资源改变了投资者的预期,使ST企业不破净或较少破净。     

股权全流通下的上市公司投资者关系管理中的博弈分析

股权分置改革的完成,我国股票市场进入全流通时代。在这一革命性变革背景下,我国上市公司投资者关系管理工作进入新的历史时刻,其重要性日益显现。正是在这一前提下,对上市公司投资者关系管理中的利益相关者进行博弈分析,具体为投资者与上市公司之间的博弈、投资者之间的博弈、股东和经营者之间的博弈、上市公司之间的博弈、公司与社会公众之间的博弈。     

基于融资考虑对股权回报率确定方法的选择

上市公司在股票市场上融资时面临两类融资考虑问题:其一是资本结构的"溢出效应",它提高了股权回报率;其二是市场投资者的认知偏差,它可能提高或者降低要求的股权回报率。FAR与NEER是确定股权回报率的两类截然不同的方法:FAR有利于实现公司价值最大化目标,而NEER能够促使短期股价最大化。在通过比较这两类方法的异同后指出,在不同的融资考虑组合下,公司应根据自身情况选择适合的方法确定项目投资要求的股权回报率。     

Brokers’ financial network and stock return

Brokerage firms are usually not only known for trading stocks for their retail clients in return for commission fee but also known for being information distributors of their clients’ investment recommenders. However, only a few studies have examined investors’ trading behaviors within a brokerage firm. This study proposes a financial network model in modeling the information diffusion process of investors within brokerage firms and investigates the potential effect of interconnectedness among brokerage firms on stock returns. We find that the centrality of brokerage firms has strong explanatory power to stock returns even if we control for the Fama–French pricing factors and other characteristics of stock.     

The Valuation Differential between Class A and B Shares: Country Risk in the Chinese Stock Market

The Chinese stock market has been characterized by a strict segmentation between domestic and foreign investors, with listed companies issuing Class A shares to domestic, and Class B shares to foreign, investors, respectively. Entitled to the same rights and obligations, however, the two classes of shares are traded at significantly different prices. The valuation differential is attributable to the different sets of investment opportunities available to domestic versus foreign investors and their risk tolerance. Foreign investors would require a higher rate of return to adjust for the country‐specific risk related to the Chinese stock market. The country risk of China can be decomposed into political risk, exchange rate risk, interest rate risk and market risk. Empirical tests provide strong evidence to support the decomposition model, showing the political risk of China as an important component.     

Capital market reactions to earnings announcements: empirical evidence on the difference in the information content of IAS-based earnings and EC-Directives-based earnings

Listing on a foreign stock exchange and the aim to attract international investors usually forces European quoted companies to adapt information supplied in financial statements to different information needs of international investors. Because of the dominance of the American stock market, this adaptation raises especially the question whether Anglo-American-oriented accounting standards (for instance IAS — International Accounting Standards) convey a higher information content for investors than continental-Europe-oriented accounting standards (for instance EC-Directives). The study examines the information content of earnings announcements, i.e. abnormal returns resulting from un-expected earnings, for a sample of Swiss quoted companies which have changed the accounting standard used for presenting Swiss GAAP consolidated financial statements to either EC-Directives or IAS and can therefore contribute to this discussion. The results of the study suggest that IAS-based earnings announce-ments convey a statistically significant higher information content than earnings announcements based on the Swiss GAAP if a variance-approach is used. For investors in the Swiss capital market, the switch from Swiss GAAP to IAS has therefore increased the information content of financial statements. But comparing IAS-based and EC-Directives-based earnings announcements, the results suggest that for investors IAS-based earnings do not possess a statistically significant higher information content than EC-Directives-based earnings. This result has been achieved despite the fact that for Swiss financial analysts financial statements based on IAS convey a significant higher information content than financial statements based on EC-Directives. Avoiding problems in specifying a model for unexpected earnings by standardizing the mean of the abnormal returns of each event window to a positive value does not lead to a different conclusion if the variance approach is used.
