【摘要】 在证券市场不断发展与开放的环境下,市场潜在的风险不断暴露与深化。波动性成为衡量市场风险的一个重要指标。为了稳定证券市场,促进其健康有序的发展,就需要控制风险,将风险降低在可以接受的水平,从而降低市场波动性的振动幅度。市场投资群体的多元化成为可行方案之一。在此基础上,证券投资基金得到了大力发展,尤其是开放式基金。随着开放式基金的发展,基金的规模占市场份额的比重加速上升,开放式基金对股票市场波动性的影响程度也逐渐加深。围绕开放式基金对市场波动性的影响:是加剧市场的波动性还是稳定市场的论题成为关注的焦点。本文研究的主题:探讨开放式基金对股票市场波动性的影响。从研究股票市场波动性的特征出发,引入开放式基金,并通过GARCH模型、EGARCH模型的对比分析,揭示出开放式基金对股票市场波动性的影响。本文研究的内容:文章的第一部分主要论述开放式基金的相关概念、特征以及开放式基金的发展现状。第二部分介绍股票市场波动性的相关理论,其中包括波动性的衡量标准、影响因素和特征等。第三部分从行为金融学的角度,分析开放式基金的羊群行为、操纵行为及正反馈交易行为等对股票市场波动性的影响。第四部分在第三部分的基础上,首先分析了上证指数日收益率的波动特性,之后建立GARCH模型与EGARCH模型具体分析开放式基金对股票市场波动性的影响,并得出相关结论。本文的研究目的在于:说明开放式基金对市场波动性的具体影响,是加剧还是稳定,并在此基础上,结合中国的实际,具体分析产生这种现象的原因。通过本文的分析得出,开放式基金加剧了市场的波动。在不同的市场环境下,基金对市场的稳定作用表现的非常微弱,相反更多的是表现出对市场的助涨助跌作用。从而得出结论:即开放式基金加剧了股票市场的波动性。之后对此结论分析了具体的原因以及相应的解决对策。希望通过本文的研究,为开放式基金的进一步发展及如何稳定市场提供一些研究思路。更多还原
