Investor attention,firm-specific characteristic,and momentum: A case of the Korean stock market

This study examines the sources of negative momentum profits by combining investor attention and the properties of common and firm-specific factors. We choose the Korean stock market as a good case to characterize the negative momentum profits identified in Asia. In both portfolio and stock analyses, a method is devised to generate return data involving the property of each common and firm-specific factor within stock groups by investor attention. This study found significant negative momentum profits within the stock group with high investor attention. This momentum effect is highly dependent on the reversed performance of the past loser portfolio, not the continued performance of the past winner portfolio, and this reversal is strongly attributable to the properties of firm-specific factors, and not those of common factors. These results are robustly consistent regardless of changes in empirical design and the consideration of influence factors, market dynamics, and other stock markets.     

关系型会计信息系统——投资者关系管理视角下的会计信息系统

投资者关系是资本市场上资金的供给方（投资者）与需求方（企业）之间的关系。会计信息系统是资金需求方在其内部构建的,为价值管理、价值创造提供决策信息的系统。在经济一体化、信息技术飞速发展的今天,在资金流动并增值的整个过程中,投资者关系管理（IRM）与会计信息系统（AIS）密不可分又各有分工,共同完成价值管理与价值创造。将以客户关系管理为主的关系型企业的模式应用于资金流方面,关系型AIS用全新的视角看待投资者关系,并充分地利用现代信息技术进行资金流上的关系管理,以发现、对话、制度为管理框架,实现价值创造的最终目标。     

中国股市反应偏差的投资者心态模型

在行为金融学理论中,投资者心态模型将投资者的心理偏差当作反应偏差的源泉,但这些投资者心态模型对于发展时间较短、具有区别于成熟市场的独特市场制度和社会环境的中国股票市场而言,存在适用度问题。分析中国股票市场投资者普遍的投机心理等要素,运用改进了的HS模型,根据股票市场的习惯,分别对一个牛市周期和熊市周期进行验证得出,投机心理支配下的机构投资者和个人投资者的相互作用是导致反应偏差的主要原因。     

Influence of Culture on Earnings Management: A Note

This article examines the influence of national culture on earnings management across a broad cross-section of countries. In addition to examining the relation between culture and earnings management in general, two different types of earnings management are examined, namely, earnings smoothing and earnings discretion. Regression results indicate that, as expected, the cultural dimensions of uncertainty avoidance and individualism are significantly related to earnings management, even after controlling for investor protection and other legal institutional factors. Culture has a stronger relation with earnings smoothing than with earnings discretion, and cultural dimensions explain a greater percentage of the variation in aggregate earnings management and earnings smoothing than do investor protection variables. These findings suggest that there is a significant link between culture and cross-national differences in earnings management, especially in the form of earnings smoothing.     

A non-linear approach for predicting stock returns and volatility with the use of investor sentiment indices

The popular sentiment-based investor index S^BW introduced by Baker and Wurgler (2006, 2007) is shown to have no predictive ability for stock returns. However, Huang et al. (2015) developed a new investor sentiment index, S^PLS, which can predict monthly stock returns based on a linear framework. However, the linear model may lead to misspecification and lack of robustness. We provide statistical evidence that the relationship between stock returns, S^BW and S^PLS is characterized by structural instability and inherent nonlinearity. Given this, using a nonparametric causality approach, we show that neither S^BW nor S^PLS predicts stock market returns or even its volatility, as opposed to previous empirical evidence.     

The role of political uncertainty in Australian financial markets

Within the developed world, recent Australian political history is uniquely turbulent. This situation invokes indecision regarding investment decisions in both the real economy and the financial markets. This paper explores the relationship between uncertainty in Australian federal election polling and resulting financial market uncertainty. Empirical evidence suggests that increasing (decreasing) levels of uncertainty around the election result induce higher (lower) levels of uncertainty in financial markets. The effect is more pronounced as polling day approaches. Industry‐level analysis suggests that the base materials sector is most significantly affected by election uncertainty in Australia.

我国社保基金持股偏好研究

社保基金在证券市场上的投资表现会直接影响其运行的稳定性,由于其资金来源的特殊性,社保基金对于选择投资对象有没有明显的偏好呢？本文利用2008—2018年我国A股上市公司的数据,研究社保基金的持股偏好。研究表明,社保基金在进行投资时对于经营业绩好、风险性低、股权集中度高、估值偏低的股票具有明显的偏好。进一步研究发现,与保险公司偏好股权集中度低的股票、公募基金偏好流动性高的股票相比,社保基金更偏好股权集中度高的股票,而对于流动性高的股票并没有明显的偏好。     

危机背景下金融消费者保护法律制度研究

美国金融危机中凸显的众多金融消费者利益严重受损的事实使我们意识到,金融产品尤其是金融衍生品的复杂特性使得金融消费者比一般消费者更为弱势,需要专门的机构和立法予以特别保护。我国对金融消费者尚无准确的界定,金融消费者很难列入《消费者权益保护法》的调整范畴,其他涉及金融消费者保护的内容散见于诸多法律法规和部门规章中,可以借鉴美国金融改革的有益经验,逐步完善我国金融消费者保护法律制度。     

内部控制、治理环境与投资者保护

本文研究了内部控制质量对投资者保护的影响,以及不同治理环境对内部控制治理功能的影响。研究发现:内部控制质量的提高,或更为充分的内控信息披露有助于抑制大股东资金占用,有助于抑制经理人与股东之间的代理成本;治理环境越差的地区,内部控制治理效应越高。这说明,对于投资者保护较弱的地区,内部控制可能成为补偿弱投资者保护负面影响的一种替代机制。本文研究意味着,近年来推出的内部控制相关制度起到了积极的效果;此外,完善上市公司内部控制,对于治理环境较差、投资者利益得不到有效保障的地区显得尤为重要。
