羊群行为在证券市场较为多见.本文运用修正后的Lakonishok等的羊群行为测度对2003年3月-2005年3月国内开放式基金的投资组合进行分析,显示其羊群行为较为严重;通过对股票各种特征的羊群值分析,也得出一些有意思的结论.     

中国开放式基金赎回现象的实证分析及成因探讨

本文运用至2005年第二季度所有成立的开放式基金的历年规模数据,对基金的赎回状况进行实证分析。研究表明,我国开放式基金的赎回存在着一些非理性的行为,这与我国证券市场制度上的一些缺陷、投资者追求处置效应、基金公司的同质趋势等因素是分不开的。     

中国开放式基金业绩持续性实证研究

中国基金市场羊群效应对基金效绩的影响——毖于基金样本的实证研究

基于基金样本数据,建立回归模型,研究羊群效应对基金效绩的影响。得出我国基金市场上有比较明显的羊群效应,且羊群效应和基金绩效之间存在负相关关系的结论。     

开放式基金申赎过程中的羊群行为

由于和传统的股票投资相比,基金作为专业化经理人管理的组合投资,具有能分散风险、节省时间成本的特点,因而逐渐成为个人投资者投资于股票市场的重要方式。由于个人投资者从以往直接投资于证券市场转变为主要通过购买基金间接投资于证券市场,一系列的理论和现实问题随之产生。在近年的几次股市波动中,通常会伴随着基金的巨额申购和赎回,这增加了基金管理的难度。基金投资者的大量赎回或申购行为使得基金的市场稳定功能受到了质疑,也使得基金公司及其代销机构的基金销售业务规模和销售收入出现剧烈波动,存在潜在的风险。     

中国开放式基金营销研究

对开放式基金业绩持续性的实证研究

近年来,基金市场大规模发展,尤其是开放式基金,已经成为中国证券市场上重要的机构投资者,对于开放式基金业绩持续性的研究具有十分重要的现实意义。本文选取了2004年以前成立的13支基金,运用斯皮尔曼秩检验方法对基金业绩持续性进行了研究,并得出了我国开放式基金整体的绝对业绩不具有持续性的结论。     

Herding in the German Mutual Fund Industry

This paper analyses the trading activity of German mutual funds in the 1998–2002 period to investigate whether German mutual fund managers are engaged in herding behaviour. Another objective of the study is to determine the impact of this herd‐like trading on stock prices. Our results provide evidence of herding and positive feedback trading by German mutual fund managers. We show that a significant portion of herding detected in the German market is associated with spurious herding as a consequence of changes in benchmark index composition. Investigating the impact of mutual fund herding on stock prices, we find that herding seems to neither destabilise nor stabilise stock prices.

Institutional Herding in the ADR Market

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.     

Institutional Traders' Behavior in an Emerging Stock Market: Empirical Evidence on Polish Pension Fund Investors

Abstract:   In this paper, we contribute to the literature on institutional herding and feedback trading by analysing the investment behavior of pension funds on the Polish stock market. Pension funds entered into the stock market due to the national pension system reform in 1999, providing a unique opportunity to receive deeper insight into the behavior of institutional investors in an emerging capital market. Our results show that Polish pension fund investors are to a greater extent involved in herd‐like behavior and pursue feedback trading strategies more often than their counterparts in mature markets. This finding is primarily attributed to a stringent investment regulation and high market concentration. We do not detect, however, that trading by the pension funds exerts significant influence on the future stock prices.     

我国证券投资基金羊群行为的实证研究

国外的研究显示，发达国家市场机构投资者的羊群行为并不十分明显。作为新兴市场主体的中国机构投资者在这方面的行为特征如何呢？本文使用经典的LSV方法以及Wermers扩展方法，对我国金融市场上以证券投资基金为代表的机构投资者交易行为进行了实证研究。结果发现，我国证券投资基金之间具有较明显的羊群行为，并具有以下特点：同时使用正负反馈操作策略；在流通盘较大和较小的股票上的羊群行为显著；成长型基金的羊群行为显著等。针对这些发现，笔者探究了羊群行为产生的原因，并提出了一些避免过度羊群行为的措施．     

中国A股市场羊群行为的实证分析

以2010年至2018年A股市场数据为样本,实证检验了中国A股市场的羊群行为。研究发现:第一,沪深两市没有检测到显著的羊群行为,从公司规模和性质来看,上证超大盘市场和上证央企市场存在羊群行为,小规模和民企市场不存在羊群行为;第二,市场暴涨暴跌期间容易产生羊群行为,且上涨行情和下跌行情的羊群行为不对称,下跌时更容易产生羊群行为;第三,B股市场涨跌对A股市场投资者的羊群行为具有一定抑制作用。基于此,提出如下建议:一方面,对个人投资者而言,应当时刻保持风险意识,加强对投资理财知识的学习,避免盲目跟风,追涨杀跌;另一方面,对政府监管部门而言,积极开展投资教育活动,培养投资者理性投资的良好习惯,同时加强市场监管,完善市场交易制度,防止出现市场暴涨暴跌行情。     

中国证券市场羊群行为实证研究

引言 羊群行为(Herd Bchavior)是指投资者在交易过程中观察并模仿他人的交易行为,从而导致某段时期内买卖相似的股票.20世纪90年代以来,随着金融学术界将研究重点转移到非基础经济因素对股价的影响上,投资者行为、特别是羊群行为对股价的影响得到了广泛关注和研究.     

International Equity Asset Classes in the Turkish Fund Industry

We examine Turkish fund portfolios and identify the role of international investments in their formation. We find that (1) Turkish funds hold a very small fraction of international assets during 1987-2008, (2) the weight of international equity in the funds with an international mandate is smaller than the total weight of domestic asset classes as of 2009, and (3) international stock holdings of Turkish portfolio managers show significant similarity, which can be explained by the fact that the managers tend to hold stocks with which they are familiar. We compare the performance of funds that have the international investment objective with benchmark portfolios and provide suggestions for more diverse funds in the Turkish fund industry.     

The Effects of Stock Characteristics on the Direction and Extent of Herding by Foreign Institutional Investors in the Taiwan Stock Exchange

We use a dynamic herding measure to explore the causes of foreign institutional investor (FII) herding in the Taiwan stock market and examine the effects of stock characteristics on the direction and extent of such herding. We find that FII herding primarily results from cascades rather than habit investing or momentum trading. The result of a panel smooth transition regression shows that FIIs' negative cascades focus on their largest net purchases of stocks, but FIIs' positive cascades focus on winner and small-sized stocks. To increase portfolio returns, investors can use FIIs' cascades to inform their stock purchases.
