A股、H股市场羊群行为实证研究

本文采用分散度指标和偏离度指标对2005-2008年间交叉上市A股和H股市场的羊群行为进行了实证检验．发现A股市场存在羊群效应,但未发现H股市场上的羊群效应。本文认为两地市场在投资者理念、市场结构、信息披露、政府监管方面的差异是造成这种差异的根源,并在此基础上提出了政策建议。本文的研究将对企业在两地市场上投融资,各类投资者规避风险获得稳定收益,两地金融市场的一体化乃至中国资本市场的长远发展具有一定指导意义。     

我国股票市场羊群行为的实证分析

运用CSAD（横截面绝对收益率偏离度）指标对市场整体收益率进行回归的方法,对样本区间沪、深股市所有上市公司股票收盘价数据进行整体和分阶段的实证分析,发现在样本期间内,我国股票市场在整体上存在显著的羊群行为,并且羊群行为存在一个减少的趋势。从市场分组研究发现,在市场上涨情形下存在类似的羊群行为和类似的发展趋势,而在市场下跌情形下羊群行为呈现出不同的特征,存在一个由不显著到显著逐步递增的趋势。

Herding in Open-end Funds: Evidence from China

This paper aims to detect the herding of Chinese open-end fund managers and examine the role that structural features of their industry play in their herding. The herding behaviour is investigated by employing the cross-sectional absolute deviation (CSAD) model, drawing on the Chinese open-end fund market for the 2007–2020 period. Our findings suggest that the presence of herding has been confirmed in all other types of funds except for income funds, with their herding being mainly driven by non-fundamental factors. Most types of funds show more pronounced herding when the market is rising and the fund flow is positive. Up markets foster positive fund flows, which promote herding to a certain extent. The structural characteristics of fund networks of common asset holdings produce an impact on the fund herding. Herding is observed in the network with larger centrality index and the disassortative network. Moreover, we also find that herding in most types of funds is more pronounced under conditions of high volatility and high economic policy uncertainty, and the fund herding tends to grow inversely with fund-size.     

从行为金融学角度分析股市羊群效应

本文运用行为金融学的相关理论羊群效应进行理论分析,然后采用CCK模型通过对上证在2008年全年的期间横截面绝对偏离度(CSAD)和市场收益率的非线性关系进行检验,得出沪市指数在这期间存在比较明显的羊群效应。最后我们为消除非理性羊群效应提出了相关政策建议。
