机构投资者实地调研能否缓解股价同步性——基于我国A股上市公司的经验证据

本文以2014-2018年我国深圳A股上市公司为样本,实证检验了机构投资者实地调研与股价同步性的关系,并探究了信息披露质量和机构投资者持股比例对此关系的调节作用.研究结果表明,机构投资者实地调研提升了公司的特质信息含量,显著降低了股价同步性.进一步研究发现,机构投资者实地调研对股价同步性的降低作用在信息披露质量较好的公司和机构持股比例较大的公司更为显著.本文的研究不仅拓展了现有关于机构投资者信息中介作用的研究,丰富了关于股价同步性影响因素方面的相关文献,并为监管部门完善上市公司信息披露制度、引导投资者与上市公司深入交流,提供了有益启示.     

基于机构投资者视角股价同步性现象研究

本文以2008到2010年深证A股主板404家公司985个面板数据为研究样本,从信息经济学和行为金融学视角分析了"套利交易"和"噪音交易"活动对股价同步性的影响机制,并以此来探讨机构投资者的证券投资行为对股价同步性的影响。实证结果表明:机构投资者基于价值投资的长期持股行为能够显著地提高个股价格的信息含量,从而降低股价同步性;反之,机构投资者基于噪音交易的短期投机行为反映的是与公司基本面无关的价格波动,会加剧证券市场的股价同步性。

分析师跟踪、投资者关注与股价同步性

中国证券市场的参与者水平参差不齐,专业分析师提供的增量信息是否充分的被普通投资者吸收和消化,现有的文献并未清晰的回答上述问题。本文建立实证分析模型,首先验证2008-2012年A股上市公司分析师跟踪与股价同步性之间的关系,然后,利用百度搜索指数作为投资者关注的代理变量,将普通投资者关注作为调节变量加入模型,分析普通投资者关注对上述关系的影响,依据机构持股比例分组进行回归分析,以期观察在机构投资者不同时普通投资者对分析师报告利用的效果。研究发现:中国证券分析师能提高股价的信息含量,而普通投资者对上市公司的关注会降低股价的信息含量,同时,其无法有效的解读分析师报告;在机构持股比例较高的样本组中,普通投资者对分析师报告股价同步性降低的效应要弱于机构持股比例较低组。上述发现不仅丰富了公司信息环境方面的文献,更揭示了普通投资者的信息解读效应。     

机构持股对股价宏观波动影响的非对称性

本文利用Topview机构投资者日持股数据,构建机构投资者日净买率等指标,使用GMM回归、递归回归,从波动、收益两个角度动态分析机构投资者对股价宏观波动的影响。实证结果表明,机构投资者对股价宏观波动的影响因不同的市场状态而具有非对称性,并可以用信息假说进行解释。管理层应依据不同的市场状态而采取合适的措施以实现机构投资者的稳定作用。     

机构投资者降低了股价崩盘风险吗?

本文以2003-2013年中国A股上市公司为样本,考察了机构投资者持股比例与股价崩盘风险之间的关系。研究发现,机构投资者持股显著增大了公司股价未来崩盘的风险。在考虑了机构投资者异质性和内生性等因素的影响后,该结论依然成立。进一步研究发现,在信息不对称程度较高的公司中,机构投资者持股比例与股价崩盘风险之间的正相关关系更强;公司所在地区的制度环境越完善,上述正相关关系越弱。渠道分析表明,机构投资者对股价崩盘风险的正向影响一定程度上源于它加剧了信息不对称。本文拓展了股价崩盘风险影响因素研究,丰富了机构投资者持股经济后果的相关文献,对监管部门积极引导机构投资者、维护资本市场平稳健康发展,具有一定的启示意义。     

机构持股对股价微观波动影响的非对称性

文章利用topview机构投资者日持股数据,构建股价波动率与机构投资者日净买率等指标,使用GMM回归、滚动回归、递归回归,从个股角度动态分析机构投资者对股价微观波动的影响。实证结果表明,机构投资者对股价微观波动的影响因不同的市场状态而具有非对称性,并可以用信息假说进行解释。管理层应依据不同的市场状态而采取合适的措施以实现机构投资者的稳定作用。     

机构投资者持股与流动性成本——来自中国上市公司的经验证据

现有的研究认为,机构投资者通过两个渠道影响流动性成本:逆向选择和信息效率。一方面,因信息不对称而带来的逆向选择问题会增大流动性成本;另一方面,机构投资者通过股票交易使私有信息渗透到股价之中,则会提高信息效率,减少流动性成本。因此,机构投资者与流动性成本之间的关系成为一个实证问题。本文研究发现,我国机构投资者持股增加了报价价差、有效价差和PIN值;进一步地,证券投资基金持股比其他机构投资者持股更可能导致流动性成本的增加。因此,我们认为,监管层应严厉打击机构投资者获取内幕信息,加强上市公司信息披露监管,减少逆向选择问题,同时应减少机构投资者操纵股票市场等影响股价信息效率的行为。     

机构投资者的彩票类股票交易行为与股价同步性

文章使用Kumar（2009）提出的低股价、高特质波动率和高特质偏度识别股票的彩票特性,利用2010至2012年A股市场的大样本数据,实证分析了机构投资者的博彩偏好及对股价同步性的影响。结果表明,我国机构投资者存在明显的博彩偏好;且这种博彩偏好会提高股价波动的同步性程度。这一结论从博彩偏好的视角,为机构投资者有限理性造成的股价同步性的存在提供了新的证据。     

ESG信息披露对股价同步性的影响

本文以2009—2021年沪深A股非金融上市公司为样本，考察了ESG信息披露对股价同步性的影响和作用机制。研究表明，企业ESG信息披露表现越好，股价同步性越高。ESG信息披露从内部通过提高公司的信息透明度，从外部通过抑制投资者情绪波动，进而提高股价同步性。进一步研究发现，在分析师关注度较低、机构投资者持股比例较低的情境下，ESG信息披露对提高股价同步性可以发挥更大的作用。本文研究拓展了我国ESG信息披露的经济后果，为促进我国企业ESG信息披露与完善该制度建设具有借鉴意义。     

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.

The case for management history

This article defines the case for treating management history as a discrete subject area, although one closely related to business, accounting, labour, and industrial history. It seeks to concentrate on the nature, process, and practice of management as an activity within the organization, and to argue that it is important that modern British managers understand the intellectual and cultural roots of their profession, since without these they will tend to be swayed by short-term management 'fads'. Within the broad topic there are several identifiable sub-areas for potential exploration, including the comparative historical development of management between different countries, management institutions, managerial careers and labour markets, management structures, management skills, and management thought and theory.     

The life and career of John Spence Ogilvy (1805-71), the first chartered accountant to emigrate to Australia

So far as the available evidence allows, this paper examines the life and career of John Spence Ogilvy, foundation member of the Society of Accountants in Edinburgh in 1854, who emigrated to Melbourne in 1856, but did not play a part in the development of an organized accounting profession in Australia. The paper also attempts to explain the gap of thirty-two years between the formation of the first accounting bodies in Edinburgh and Melbourne.

Cost accounting standard and cost accounting systems in Japan. Lessons from the past - recovering lost traditions

This paper aims to show two things. The first is how Japanese culture has contributed to the development of Japanese cost accounting history. The second is to reveal the research possibilities of cost accounting history. This paper also reviews the salient features of several important examples of these aspects of cost accounting practice in Japan. It therefore explores, through some practical illustrations, how and why Japanese cost accounting differs from that found in the West.
