机构投资者的投资行为对股票市场的风险与收益产生了极大的影响,机构投资者的大量参与有助于股票市场的稳定、特质风险的分散以及超额收益的减少。文章选取机构投资者持股占股票市值比例这一指标来刻画机构投资者的行为,检验机构持股比例、特质风险和股票收益之间的关系。实证发现,在中国股市,特质风险与股票收益呈显著的正相关关系;机构大量持股有助于降低股票的特质风险;机构投资者持股比例越低的股票,特质风险越大,股票预期收益越高。  相似文献

本文以2007~2009年我国上市公司的过度投资行为为背景,考察机构投资者持股对过度投资的治理角色。研究结果表明,机构的期末持股比例、长线型机构投资者尤其是长线型基金与过度投资显著负相关,表现为有效监督者的角色;短线型机构投资者则缺乏公司治理的意愿和动机,表现为利益攫取者的角色。研究结果意味着,我国的机构投资者同时具备有效监督者和利益攫取者的角色,何时表现出何种角色取决于持股比例以及持股时间。  相似文献

由于会计信息的专业性,个人投资者往往难以从会计数据中识别盈余管理;而作为投资专家的机构投资者能否识别盈余管理,并将其融入到市场价格机制中则成为人们关注的焦点。通过检验机构投资者持股对公司股票累计超额报酬率和盈余管理之间关系的影响,研究发现:机构投资者持股较高的股票的超额报酬率与正向操纵性应计利润显著负相关,说明机构投资者股东能从会计信息中识别公司的盈余管理行为,并将其反映到市场价格机制中去。  相似文献

保险公司的投资特征直接影响保险公司的业绩水平和保险行业的健康发展。在众多投资渠道中,持股偏好最能体现保险公司投资特征:数量众多的股票,在风险和流动性等方面存在显著差异。偏好何种类型股票,能够较为全面反映保险公司的投资行为特征。利用2006年~2011年上市公司股权结构数据对保险公司持股的偏好进行考察;研究结果发现,与非保险类的机构投资者不同,保险公司的股票投资表现出对于安全性和流动性的更强烈偏好。这种持股偏好与保险公司的资金来源性质和业务运营特点相匹配。当放宽投资范围约束时,保险公司对于流动性较高的股票和风险较低的公司有更加明显的投资偏好。  相似文献

机构投资者持股与股价同步性分析   总被引:1,自引:0,他引:1  
本文利用中国证券市场所有A股上市公司2005~2007年的面板数据,对股价同步性和代表机构投资者持股的三个变量——机构投资者持股比例、机构投资者持股变化和持股机构投资者数量进行回归统计,检验了机构投资者持股对股价同步性的影响。研究表明,代表机构投资者持股的三个变量都与股票股价同步性显著负相关,其中机构投资者持股变化是影响股价同步性的决定性因素,其他两个变量都是通过该变量发生作用的。这一结果说明机构投资者利用公司特质信息进行的基于信息的交易提高了股价中的信息含量,降低了股价同步性。  相似文献

本文采用月相变化这一外生变量衡量投资者情绪的周期性波动,使研究避开了复杂的社会影响过程而专注于外生性的影响。研究发现,股票收益的运行轨迹与投资者情绪周期性波动的轨迹相同,即股票收益会随着投资者情绪的周期性波动而呈现出同样频率的循环性波动。这一现象无论在机构投资者重仓还是中小投资者重仓的股票中均存在,而机构投资者持股比例的增加可以减弱投资者情绪周期波动对决策行为的影响。股市周期作为一种经济环境的刺激变量,在牛、熊市下对投资者机体变量的作用不同,导致其反应变量出现不同程度的变化,在牛市阶段,投资者情绪周期波动对股票收益的影响更为强烈。与非周期性行业相比,投资于周期性行业时,决策所涉及的风险和不确定性更大,放大了情绪波动对于决策行为的作用,导致股票收益随投资者情绪周期性波动而循环性波动的现象在周期性行业中更为明显。  相似文献

近几年来,借鉴西方成熟市场的发展经验,我国开始大力发展以投资基金为代表的机构投资者,希望发挥机构投资者的专业能力和信息优势稳定股票市场、降低投资风险。但机构投资者在我国资本市场是否真正起到了应有的作用仍是一个有待商榷的问题。本文以1999年至2007年沪深两市上市公司数据构建面板数据,研究了机构投资者持股比例对股票收益率波动的影响,实证结果证明机构投资者持股比例与股票收益率波动负相关,机构投资者对我国股票市场起到了一定的稳定作用。  相似文献

对于机构投资者是否具有稳定证券市场的作用,国内外学者、专家各持其说.在中国证券市场上,由于以证券投资基金为主的机构投资者持股集中度普遍较高,表现为较高的股票集中度和行业集中度,对证券市场的影响较大.因此本文就机构投资者对证券市场的稳定性进行进行探讨.  相似文献

利用英国市场226家非金融、非公共事业类企业2005年至2010年期间机构投资者持股数据,通过联立方程组的回归方法,研究不同类型机构投资者对于公司业绩的影响.总体来看,英国市场机构投资者持股水平的变化并未对公司业绩的提升起到显著的作用,原因在于:机构投资者持股水平的变化会相互影响,同时部分机构投资者持股水平受到公司业绩好坏的影响.这使得不同机构投资者持股水平的变化对于公司业绩提升虽有差异化影响,但效果较弱.  相似文献

机构投资者股东积极主义逐渐被西方认同,尤其是稳定型机构投资者,受长期利益驱动而积极参与公司治理。中国国企因受政府干预,机构投资者的作用有待进一步检验。本文选取国企并购样本,考察异质的机构投资者股东对国企并购绩效的影响。结果表明,交易型机构投资者持股与国企并购绩效显著正相关,稳定型机构投资者持股未体现出明显的治理效果;进一步研究发现,在国企的关联并购中,交易型机构投资者的作用也不再显著。我们认为,我国交易型机构投资者多为主动投资,会积极参与国企监督与决策,稳定型机构投资者在国企中的投资多为被动投资,不关心个体的经营;国企关联并购中的政府干预更强,使得交易型机构投资者也无法发挥作用。本文将为国企混合所有制改革中机构投资者的引入提供支持。  相似文献

Abstract:  This paper examines the relation between the speed of price adjustment and stock ownership by foreign and local institutional investors using data from the Korean stock market. We show that returns of stocks with high foreign institutional ownership lead returns of stocks with low foreign institutional ownership, especially after foreign ownership restriction is lifted. Likewise, returns of stocks with high local institutional ownership lead returns of stocks with low local institutional ownership. These results support the idea that foreign institutional (local institutional) investors have faster access to or processing power of new information than local institutional (local individual) investors.  相似文献

Recent studies show that single‐quarter institutional herding positively predicts short‐term returns. Motivated by the theoretical herding literature, which emphasizes endogenous persistence in decisions over time, we estimate the effect of multiquarter institutional buying and selling on stock returns. Using both regression and portfolio tests, we find that persistent institutional trading negatively predicts long‐term returns: persistently sold stocks outperform persistently bought stocks at long horizons. The negative association between returns and institutional trade persistence is not subsumed by past returns or other stock characteristics, is concentrated among smaller stocks, and is stronger for stocks with higher institutional ownership.  相似文献

A growing literature evaluates the relation between lag returns and demand by institutional investors. Given that lag returns and institutional ownership are directly observable, it is surprising that previous tests yield dramatically different conclusions. This study examines differences across studies and finds that four factors account for these discrepancies: (1) value‐weighting versus equal‐weighting across stocks, (2) averaging versus aggregating over managers, (3) disagreement in the signs of measures of institutional demand, and (4) correlation between current capitalization and both lag returns and measures of institutional demand. Controlling for these factors, the results across different methods are remarkably uniform.  相似文献

We examine the informational role of geographically proximate institutions in stock markets. We find that both the level of and change in local institutional ownership predict future stock returns, particularly for firms with high information asymmetry; in contrast, such predictive abilities are relatively weak for nonlocal institutional ownership. The local advantage is especially evident for local investment advisors, high local ownership institutions, and high local turnover institutions. We also find that the stocks that local institutional investors hold (trade) earn higher excess returns around future earnings announcements than those that nonlocal institutional investors hold (trade).  相似文献

Of shepherds, sheep, and the cross-autocorrelations in equity returns   总被引:5,自引:0,他引:5  
We present an economic mechanism and supportive empirical evidencefor the transmission of information between equity securitiesfirst documented by Lo and MacKinlay (1990). It is argued thatthe past returns on stocks held by informed institutional traderswill be positively correlated with the contemporaneous returnson stocks held by noninstitutional uninformed traders. Evidenceconsistent with this hypothesis is then presented. We documentthat the returns on the portfolio of stocks with the highestlevel of institutional ownership lead the returns of portfoliosof stocks with lower levels of institutional ownership. Thiseffect persists even after firm size is controlled for and isapparent at longer lags than the size-related lag effect documentedin Lo and MacKinlay (1990).  相似文献

This study examines institutional herding in the ADR market between 1985 and 1998. We find a significant positive relation between changes in institutional ownership and ADR returns over the same period. The positive relation persists after we control for the momentum effect in the US stock markets. We also find that in the ADR market, past winners (losers) in the herding period continue to be the winners (losers) in the post-herding period. The lack of a returns reversal suggests institutional herding is related to momentum trading. However, the positive relation between institutional ownership changes and ADR returns remains after controlling for momentum trading in the ADR market. Our results also rule out that positive feedback trading is related to institutional herding in the ADR market.  相似文献

Herding and Feedback Trading by Institutional and Individual Investors   总被引:33,自引:0,他引:33  
We document strong positive correlation between changes in institutional ownership and returns measured over the same period. The result suggests that either institutional investors positive-feedback trade more than individual investors or institutional herding impacts prices more than herding by individual investors. We find evidence that both factors play a role in explaining the relation. We find no evidence, however, of return mean-reversion in the year following large changes in institutional ownership—stocks institutional investors purchase subsequently outperform those they sell. Moreover, institutional herding is positively correlated with lag returns and appears to be related to stock return momentum.  相似文献

We find that the sign of the correlation between institutional ownership and volatility depends on the firm’s dividend policy: institutional ownership is negatively (positively) related to volatility among non-dividend (dividend) paying stocks. The empirical results are consistent with an interaction between institutional preference for low volatility and the tendency of higher levels of institutional ownership to increase volatility through their trading behavior. This result is robust to many control variables and possible endogeneity concerns. Supporting our conjecture that institutions herd on dividend signals we find that the correlation between turnover and institutional ownership is higher for dividend paying stocks, and that the positive correlation between turnover and institutional ownership is higher on dividend declaration days. Finally, we also find that the level of institutional ownership drops following an increase in volatility for both dividend payers and non-payers, and that volatility rises following increased institutional ownership for dividend paying stocks.  相似文献

This paper investigates the influence of institutional ownership and liquidity on stock return relationships for an embryonic and relatively illiquid stock market. Using daily, individual stock data for Trinidad and Tobago from 2001 to 2015 and a VAR modelling approach, we find for firms of all sizes and levels of analyst coverage that the returns of more institutionally favoured stocks lead those with less institutional ownership. Distinctively, greater institutional coverage is shown not to be associated with greater liquidity, though liquidity levels do condition the influence of institutional ownership. This indicates that institutional owners have information advantages relative to other stock owners.  相似文献

A strong turnover premium exists such that stocks with lower turnover have higher future returns in the 5 years following their formation than those with higher turnover. This turnover premium cannot be explained by existing asset-pricing models, a risk-based liquidity factor, or anomalies such as size, book-to-market ratio, or momentum. Further analysis indicates that the turnover premium is greater for stocks with higher idiosyncratic volatility, higher transaction costs, lower institutional ownership, and lower investor sophistication, which implies it is consistent with the mispricing explanation based on arbitrage risk.  相似文献
