摘要
证券投资基金是指集合大众的资金由专家投资理财,利益共享、风险共担的资金集体。开放式基金是一种为世界基金业实践所检验的先进的基金形式,其运作机制能较好保障基金投资者的利益,能较好激励基金管理人勤勉理财,有较高的透明度,因而成为国际成熟资本市场的主导产品。股票型开放式基金主要投资于各种股票,从长期来看,股票投资的收益高于债券投资和货币市场工具投资,由于其具有专业化的管理,成熟股票投资经验等特点,越来越受到广大投资者的欢迎。我国基金业已经在风雨中经过十几年的成长之路,与国外百年的基金发展历史相比,这样一段“超常规的发展”令人感慨万千。1998年证券投资基金成立之初,基金管理公司仅有5家,管理基金资产107亿。至2008年6月30日,中国大陆基金市场已成立证券投资基金总数达到379只,发行在外的基金总份额为21509亿份。59家基金管理公司中有28家合资基金管理公司,内资公司、合资公司和QFII形成机构投资者间有效竞争的格局。
虽然关于投资基金的著述较多,但大都集中于投资基金的渊源、种类、功能以及如何进行投资等方面,而对于投资基金投资管理过程中的核心环节——投资策略方面的研究却缺乏全面性和系统性。本文将直面此方面的薄弱环节,选择股票型开放式基金作为研究对象,对股票型开放式基金的投资策略以及各种策略的投资业绩进行研究分析,探讨股票型开放式基金的策略演变过程以及今后的发展方向。文章从界定投资哲学、投资理念、投资策略、投资风格相关概念开始,结合证券投资理论的发展脉络,综合运用规范、实证、比较等研究方法,展开对投资策略的理论基础和实施方法的系统性研究。对金融异象进行了较为全面梳理和阐释,以期为投资策略的选用带来启发。对四大分析流派进行对比,探讨出在我国是否适用的问题。应用T-M模型,对样本基金的选股能力、择时能力进行评价分析,透过持股仓位变化、持股集中度的实证分析来管窥投资策略的选择和实施。基金业投资策略所呈现的趋同性和阶段性特征进行归因分析,并给出政策建议与展望。
第一章:通过对研究背景的叙述引出本文的研究方向,在分析国内外研究现状的基础上确立本文的研究主题。对证券投资基金的基本概况进行了阐述,为下文进行更为深入的研究做了铺垫。
第二章:对投资哲学、投资理念、投资策略、投资风格相关概念做出了界定,并对四者间的逻辑关系进行了形象描述,给出了简明逻辑关系图。对投资策略在收益-风险视角、分散-集中视角、积极-消极投资态度、长期-短期投资期限四种分析维度上进行分解,并在市场、类别和个股三个层次上,结合积极-消极投资态度对主要的几种投资策略进行了详细刻画。阐述了投资风格的兴起与定义,列举了数量众多的市场异象现象所演化出的几种主要的投资风格。科学化的投资流程是基金管理公司多部门间通力合作达成投资效果的有力保障,本章2.4节以易方达基金管理公司的投资决策流程为例,说明了证券投资基金的投资决策流程。
第三章:沿着证券投资理论的发展脉络,逐步阐释证券组合理论、资本资产定价理论、有效市场假说和行为金融理论及其对投资策略的影响。对各类金融异象进行了较为全面梳理和阐释,以期为基金经理人的投资决策带来启发。
第四章:对比研究四大投资分析流派,探讨出各自的适用空间以及赖以生存的环境。在“新兴加转轨”证券市场环境中,大多数基金经理人都采用积极的投资态度,频繁的进行波段操作,各种投资理念都沦为了“趋势投资的辅助工具”。
第五章:梳理了我国证券投资基金的投资策略的发展脉络。在详细分析了2008年年中信息披露信息之后,我们可以观测到基金的投资思路和策略取向。一是投资偏向于能够抵抗通胀及抵御经济回落风险的品种,强化了对系统风险的防御能力。目前的防御性企业包括民用刚性消费品如医药、食品、商业、媒体、机场和符合国家固定资产投资方向的农业投资、铁路投资、医药投资、通信等。二是“自下而上”挑选“白马股”并提高集中度,抱团过冬。通过对样本基金的选股能力、择时能力、仓位变化以及持股集中度的实证分析,发现证券投资基金的投资风格呈现趋同化和阶段性特征。针对该特征进行了归因分析,给出政策建议与展望。
第六章:全文总结
可能存在的创新:
(1)对投资哲学、投资理念、投资策略、投资风格相关概念做出了界定,绘制出了四者间的逻辑关系简明图。
(2)对投资策略和投资风格的分类进行了四分维度刻画,给出分色图
(3)对我国证券基金投资策略特别是2008年以来的持仓变化、换手率、行业配置等方面所进行的实证分析
(4)探讨了股权分置改革、大小非减持对我国投资策略选择的影响
Security capital fund refers to the capital which is pooled by the experts on investing from the massive investors for the common interests, and all the investors bear the risks. In the worldwide fund industry, open-end fund has proved its superiority in practice. Because it can guarantee the investors’interests, spirit the fund keeper, and secure the transparency, it turns out to be the leading product in the developed capital market. Stock-oriented open-end fund is mainly invested in the stock market. Generally speaking, in the long run stocks investment will yield more than the bond investment and the investment in monetary market. It is popular among the investors because the specialized management and experience in investing.
China’s capital funds have a very short history of more than ten years. Comparing with the more than 100-year-history of the developed countries’capital funds, the“extraordinary development”of china’s capital funds will shock everyone. Security capital fund were introduced to china in 1998 and there were five fund administration companies then operating RMB 10.7 billion. By the mid of 2008, the amount of capital funds increased to 349 with 2,150.9 billion fund shares. And the administration companies increased to 59. In a competitive market, the performance of the capital funds will play an important role in the development of the funds, whereas the investment strategies are the key factors that will affect the performance of the funds.
While there are so many papers about capital fund, most of them are focused on the origin, species of fund, and how to invest, few of them focused on investment strategy. The thesis studies on the stock-oriented open-end fund, its investment strategies, its evolution and where it heads for. Why does the stock-oriented open-end fund capture the eye of the writer? Because it is a mature product in capital market, and it can mirror the fund industry.
I’ll starts with the definition of investment philosophy, investment philosophy, investment strategy, investment style, and along with the road of investment theory development, hold the research on investment strategy with comparative, evidence, standardized, methods. Financial anomalies were more comprehensive, but bring the inspiration of investment strategy choice .On the sample of stock- oriented open-end funds, I’ll applicant the T-M model to evaluate the ability of open-end fund managers. Finally a conclusion of the thesis, some suggestions, references, and postscript are presented.
