处置效应是指投资者倾向于卖出盈利而保留亏损的非理性行为,本文以某5只开放式股票型基金的43.7万个人账户在2005年9月-2011年12月的交易数据为样本,采用含有依时协变量的COX生存分析法,对基金投资者的处置效应及其个体差异进行了检验。实证研究发现:(1)我国基金投资者整体上表现出明显的处置效应,COX比例风险回归分析结果显示盈利基金被卖出的可能性显著小于亏损基金。控制基金投资者的个体差异(性别、年龄、地域、开户渠道)之后,处置效应仍然显著存在;(2)基金投资者的处置效应在个体层面有如下差异:男性投资者比女性的处置效应要弱,年轻的投资者(35岁以下)处置效应较弱,开户于证券公司的投资者较开户于银行的投资者处置效应弱,处于一线城市(北上广深)的投资者相比其他地区投资者处置效应更强;(3)更换参考点以及控制理性因素如均值回复等之后,基金投资者的处置效应仍然存在。 相似文献

在资本市场,参与者既是价格的制造者,又是价格的接受者,他们不是基于同样的理由参与市场交易,他们也不会在同一个起点运行其策略,交易和投资是不同的.这样,在众多个人或组织行为的交互作用下,会产生个别人或组织暂时不得不接受或无人愿意单方面改变的结局.由于基本环境的不断变化、市场参与者之间的互动关系的变化、他们集体情绪和思维状态的演变,市场经常在不同状态(如无序、随机行走、有序)之间变化.行为金融学认为在一些情况下人的决策与经济学的理性假定有系统性偏差.它的两个基本假设是:第一,部分投资者因非理性或非标准偏好驱使而做出非理性行为;第二,具有标准偏好的理性投资者无法全部抵消非理性投资者的资产需求.这意味着,非理性投资者预期可以影响金融资产的价格. 相似文献

本文选取2012—2021年我国沪深A股上市公司为样本,研究了高管学历特征、机构投资者与企业研发投入的关系。结果表明:高管学历与企业研发投入存在正相关关系。相较于国有企业,非国有企业的高管学历与企业研发投入的正相关关系更明显;独立型机构投资者对高管学历与企业研发投入的关系起到正向调节作用;非独立型机构投资者和机构投资者整体起到负向调节作用。在不同产权性质企业中,独立型、非独立型机构投资者对高管学历与企业研发投入均具有调节作用,机构投资者整体调节效应均不显著。 相似文献

Previous studies emphasize the importance of investor legal protection on financial reporting quality. We argue that investors’ awareness of their legal rights and understanding of the financial products play complementary roles. Financially well-educated investors are more likely to be able to understand investment-related information and less likely to be tricked, hence can pressure managers to eschew misappropriate behavior. This paper explores the role of investor financial education as a corporate governance mechanism in the context of earnings quality. Using data from 43 countries during the sample period of 1994–2012, we find that earnings quality is higher in countries with better financial education after controlling for various institutional environments. Interestingly, the positive effect of financial education on earnings quality exists only in countries with stronger investor legal protection, indicating a complementary role of financial education. Our study provides evidence on the role of financial education in investor protection. 相似文献

论金融消费者与投资者的识别标准 总被引:4,自引:0,他引:4
金融消费者与投资者所标识的两类主体之间是否有本质意义上的不同,亦或只是概念上的区别并无实质性差异,这是金融消费者保护立法过程中无法回避的问题。如果两者之间确有差异,识别两者界限的标准就显得格外重要。通过分析金融契约关系中个体自然人承担的权利义务及法律风险方面的系统性差别,本文指出,将参与金融活动的个体自然人分为金融消费者与投资者具有实际意义,现有理论所提出的主观标准因缺乏明确性容易导致认识分歧的产生,资信授予客观标准的采用或许是更优的选择。 相似文献

危机背景下金融消费者保护法律制度研究 总被引:11,自引:0,他引:11
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。 相似文献

This study investigates the role of asymmetric information for the pricing, issuance volume, and design of innovative securities. By analyzing the information that structured product issuers provide to the investors of those products, we can identify specific sources of asymmetric information between the issuers and investors in this market. We show that issuers exploit this information friction to offer products to investors that appear more profitable for the issuer. In addition, we find that the friction induces issuers to design products with higher information asymmetry. Our results suggest that product issuers’ behavior increases information frictions in the financial system. 相似文献

Using search volume data on crisis-related queries from Google Trends, we estimate three different measures of market-level and individual crisis sentiment. We find that the stock performance of international banks during the period Q1 2004 to Q4 2012 was significantly driven by investors’ irrational market-wide crisis sentiment. Our empirical analysis shows that irrational market-wide crisis sentiment leads investors to devalue bank stocks irrespective of idiosyncratic or macroeconomic fundamentals. Comparing this finding with results for a sample of non-financial companies, we find evidence in support of the notion that the effect of crisis sentiment on stock returns is strongest in the absence of implicit bailout guarantees. 相似文献

利用上市公司资本公积金转增股本的现象,本文结合高频分笔数据来研究公司股价被\"拆低\"以后,公司股票是否投资者参与方面有所变化?并进一步考察这些因素是否会影响到公司在转增股本时的决策。结果发现,公司股价\"拆低\"显著地增加了公司的投资者参与度;而那些未发生股价\"拆低\"的配对样本在事件前后,投资者参与度并未发生明显差异。最后,基于序数Logit模型的结果显示,公司在转增时并未将投资者参与度放在重要的位置。 相似文献

This paper investigates the link between consumer confidence and stock returns over stock market fluctuations. In particular, I focus on whether the returns have asymmetric effects on confidence. The empirical results from both in-sample and out-of-sample tests provide strong evidence of the existence of an asymmetric linkage between stock returns and consumer confidence: the impacts of returns on confidence are larger in bear markets. Moreover, variables such as the term structure, changes in federal fund rates, changes in unemployment rates, and changes in world oil prices are found to be negatively associated with consumer confidence, as expected. 相似文献

We study the relationship between investor relations disclosure and analyst forecast properties in Australian firms, a setting dominated by small firms with limited analyst coverage and requiring continuous disclosure of price sensitive information. We find increasing disclosure in the time period investigated is associated with greater accuracy in firms disclosing fewer items. Disclosure was unrelated to forecast dispersion, possibly due to the low analyst following. In periods of uncertainty, the investor relations awards effectively discriminated quality from quantity of disclosure. These findings highlight the importance of active communication with analysts, particularly in firms providing less disclosure and during periods of uncertainty. 相似文献

本文以2001年至2009年的A股上市公司为样本,从市场角度研究财务重述与市场选择的关系。研究表明,业绩优秀的上市公司变更事务所和注册会计师会显著降低财务重述的概率,但业绩差的上市公司变更事务所和注册会计师会显著增加财务重述的概率;选择"四大"能显著降低财务重述的概率;但支付高的审计费用对财务重述的概率有显著影响,如果选择的"非四大"可以降低重述的概率,如果购买的是"四大"反会增加重述的概率。 相似文献
