我国开放式股票基金的择时选股能力研究

开放式基金的择时选股能力评价作为基金绩效评价的重要内容之一,直接影响基金投资者和基金管理公司等利益相关主体的决策行为.运用国际上成熟的基金评价模型、最新数据,对我国股票型开放式基金的择时选股能力进行实证研究的结果表明:我国基金经理专业能力较差,经营管理水平一般,并未通过其良好的选股和择时能力来实现基金收益.应采取完善证券市场结构、加强对基金从业人员的培训、强化投资风险意识等措施,提高我国股票型基金的择时选股能力.     

基金选股择时能力的评价及实证分析

本文通过T-M模型和H-M模型对我国开放式基金选股择时能力做出实证分析,最后发现我国基金基本不具备选股择时能力。     

我国开放式证券投资基金选股与择时能力分析研究

在提出偏股型开放式基金选股能力和择时能力概念的基础上,选择个案进行选股和择时的投资思路分析,并分别选用T-M二次项模型和H-M二次项模型对我国业绩排名前13的偏股型开放基金进行实证检验。得出我国开放式证券投资基金选股能力一般,择时能力较差的结论。     

熊市下我国开放式证券投资基金选股和择时能力实证研究

本文采用T—M模型、H—M模型和C—L模型对我国开放式证券投资基金在熊市下的选股和择时能力进行了实证研究。研究结果表明:大多数基金业绩具有一定的选股能力,大多数基金具有负的择时能力。     

我国股票型开放式基金选股能力和择时能力实证研究

开放式基金已经成为我国资本市场重要机构投资者,其绩效的好坏关系到整个资本市场的发展,也关系到千万中小投资者的切身利益。本文选择股票型开放式投资基金为研究对象,对其在2006年4月7日至2008年12月12日期间的选股能力和择时能力进行实证检验,结果发现在弱势市场各基金的选股能力和择时能力明显下降。     

我国开放式基金动态资产配置能力的实证研究

我国开放式基金动态资产配置能力一直深受各方关注,以市场时机把握能力为代理变量是考察基金动态资产配置能力的一个重要角度.H-M模型在检验市场时机把握能力中应用最广,同时为了克服H-M模型不足,采用更加成熟的HM-FF3模型.本文采用这两个模型对我国40只偏股型和偏债型基金在2007年1月-2010年12月分别进行选股能力分析和择时能力实证分析.研究结果表明:我国开放式基金只存在很小程度的选股能力,基本不存在择时能力.     

公募基金与阳光私募基金经理的投资能力实证分析

我国公募基金与阳光私募基金的发展从20世纪80年代末至今得到了长足的发展。主要采用TM模型和HM模型对基金经理的选股能力和择时能力进行了对比分析,总体来看,私募基金经理的投资能力优于公募基金经理。当用成功概率法进行辅助性验证的时候,发现两种激励模式下基金经理对市场方向的预测和判断基本相当,公募基金经理还略胜一筹。分析结果,我国基金行业基金经理的投资能力不具备显著的差异,投资业绩的差异关键在于对仓位的控制以及策略的灵活性。     

基于PANEL DATA的开放式基金选股择时能力的研究

本文选取了18只开放式基金2006年9月至2008年11月的数据,建立PANELDATA模型,用三因素的H-M模型对我国开放式基金的择时选股能力进行实证研究,并用3种效应的数据检验假设。结果发现(1)在本轮牛熊市轮换的过程中,基金有一定的选股能力,但不令人满意;(2)基金表现出正向择时能力,在市场经历单边上涨趋势的情况下结果显著。当市场经历单边下跌趋势的情况下结果不显著;(3)大盘股对开放式基金收益的影响较大,且基金更多投向了成长型的股票     

我国开放式基金的选股择时能力研究

我们使用T-M评价模型发现,相较于在基金市场整体上选股择时作用的微弱,以精选个股、善于把握市场机会为特点的绩优基金则有较显著的选股择时能力。但需注意的是,基金的选股择时能力要在适度的范围内考察,即应按照区分市场状态来看基金的选股择时能力。     

开放式股票基金绩效评估——基于50只基金的实证分析

本文针对我国开放式股票基金的盈利能力,风险调控能力以及基金经理的择时择股能力,基金业绩持续性等方面进行实证研究,通过选取50只开放式股票基金,利用詹森指数、特雷诺指数、夏普指数三大指标对风险调整收益能力进行评估,通过TM模型、HM模型分析我国基金经理的择时择股能力,得出关于我国开放式基金在盈利能力,风险调控能力以及基金经理的择时择股能力等方面的结论。     

Stock picking,market timing and style differences between socially responsible and conventional pension funds: evidence from the United Kingdom

As far as we are aware, this study presents the first comparative analysis of the stock picking and market timing abilities of managers of conventional and socially responsible (SR) pension funds, and of their use of superior information. For the United Kingdom, the results obtained show a slight stock picking ability on the part of SR pension fund managers (although it disappears if multifactorial models are considered), and a negative market timing ability on the part of both SR and conventional pension fund managers (these results hold for multifactorial models controlled by home bias). In relation to the management styles, both conventional and SR pension funds usually invest in small cap and growth values, although it is the SR pension funds that are the most exposed to these styles. We also observed that, while conventional pension fund managers make certain use of superior information to follow stock picking strategies, managers of SR pension funds use superior information to follow market timing strategies.     

中国开放式基金表现的动态能力研究

本文以中信指数与中信债券指数的加权超额收益率为市场基准 ,以GDP增长率和消费物价指数的增长率以及广义货币供给增长率为条件变量 ,构建了证券投资基金表现的条件评价模型 ,对中国开放式证券投资基金的选股能力和市场时机把握能力进行了测度。计量方法上采用混合数据模型的回归方法以提高回归结果的有效性。研究结论为 :中国开放式基金不但具有一定的选股能力 ,而且具有良好的市场时机把握能力 ;条件模型的解释能力高于无条件模型。     

Ability parity model for optimal fund allocation: Evidence from China's mutual fund markets

We propose in this article a novel ability parity model for optimal fund allocation. Compared with the traditional portfolio selection methods which directly work on asset returns and/or risk (volatility), the proposed ability parity method focuses mainly on the allocation between the stock selection ability and market timing ability of fund managers, which essentially determines fund performance (Fama, 1972). Using the data of China's mutual fund markets, we find strong and robust evidence that the proposed ability parity model delivers significantly higher return, skewness, and Sharpe ratio than traditional models and the benchmark index, while having volatilities comparable with traditional models.     

我国股票型证券投资基金业绩评价及实证分析

选择比较成熟的单因素T-M模型,对2008年12月22日到2010年8月27日间86个交易周的20只股票型基金进行业绩评价,考察股票型证券投资基金的基金经理是否在我国这种弱式有效的市场上具备良好的选股能力和选时能力。     

Harmony,Justice, Confusion,and Conflict in Family Firms: Implications for Ethical Climate and the “Fredo Effect”

In this study, we analyze the financial performance and the managerial abilities of religious mutual fund managers, implementing a comparative analysis with conventional mutual funds. We use a broad sample, free of survivorship bias, of religious equity mutual funds from the US market, for the period from January 1994 to September 2010. We build a matched-pair conventional sample in order to compare the results obtained for both kinds of mutual fund managers. We analyze stock-picking and market timing abilities, topics widely neglected for the specific case of religious mutual fund managers. We also study style timing abilities. As far as we are aware, this aspect has not been studied previously for religious mutual fund managers. Our results indicate that religious mutual fund managers underperform both the market and their conventional counterparts. This result is driven by negative stock-picking ability which could be generated by excluding “Sin” stocks from their portfolios. Moreover, they are not able to time the market or any of the following styles: size, book-to-market, and momentum.     

The Canadian Hedge Fund Industry: Performance and Market Timing

We analyze the risk and return characteristics of Canadian hedge funds based on a comprehensive database we compiled. We find that Canadian hedge funds have higher risk‐adjusted performance and different distributional characteristics relative to the global hedge fund indices. We investigate market timing by Canadian hedge funds and find that they do not time the Canadian or global stock and bond markets, but hedge funds in the Managed Futures strategy group time the commodity market. These results are robust to parameter instability and structural changes in the model. We also illustrate the impact of using local and global risk factors to analyze the performance of local investment firms.     

Do hedge funds time market tail risk? Evidence from option-implied tail risk

This paper focuses on an unexplored dimension of fund managers’ timing ability: Market-wide tail risk implied by information in options markets. Constructing the option-implied tail risk, we investigate whether hedge fund managers can strategically time the tail risk through adjusting their exposure to changes of it. Using an extensive sample of equity-oriented hedge funds, we find strong evidence of tail risk timing ability of hedge fund managers. Furthermore, tail risk timing ability brings significant economic value to investors. Top-ranked funds outperform bottom-ranked funds by 5–7% annually after adjusting for risk factors. Our results are robust to various robustness checks.     

Investor sentiment and advertising expenditure

A strategic issue facing marketing managers is ‘how much and when’ to spend on advertising. We argue that investor sentiment in the stock market may influence advertising expenditure by affecting firms' ability to raise new funds. We show that during periods of low (high) investor sentiment, firms decrease (increase) their advertising expenditure, even though the effectiveness of advertising is greater (lower) during such periods. We also find that these results are stronger for financially constrained firms that rely more on external financing. Our findings suggest that marketing managers can improve the efficiency of their advertising expenditure by raising (reducing) it during periods of low (high) sentiment.     

Psychological Capital: Impacts on Asset Management

Drawing together the areas of behavioral finance and positive psychology, the present research sought to investigate whether the psychological capital of investment fund managers is associated with fund performance in a context of financial instability. The theoretical propositions were presented and evaluated empirically through primary data on investment fund manager profiles and secondary data on the cumulative stock fund returns. The results indicate that funds managed by managers with greater resilience and optimism obtained a higher return than the mean profitability in a period of market instability.     

VaR在我国开放式基金绩效评价中的应用研究

通过按照开放式基金的种类,选取一级市场上30只开放式基金为样本,采用基于VaR的RAROC方法,运用统计学软件Eviews中处理厚尾现象著称的GARCH模型进行统计分析,得出的结论是:成长型基金的绩效低于股票基金标准;平衡型基金和收入型基金的RAROC值相对较高,超过了股票基金标准;指数型基金的绩效超过股票标准(市场数据);在债券种类中,债券基金的绩效最高。
