基于风格调整的开放式基金业绩评价实证研究

基金的投资风格对于基金业绩有重大影响,将不同投资风格的基金业绩直接进行对比,不能科学地体现基金表现的优劣。本文以2005年4月1日到2009年11月30日期间经历了一个完整的上涨和下跌行情的我国51只开放式股票型基金为样本,运用Fama-French三因素模型对基金的投资风格进行检验,并在剔除风格因素后对基金业绩进行评价,结果发现我国开放式股票型基金投资风格严重趋同,表现为大盘成长型。经过风格调整之后,基金取得了一定的超额收益。     

基金管理模式、投资风格与经营绩效:来自中国公募基金探索性研究

随着基金规模的扩大和需求的多元化,越来越多的基金采用两人或以上的团队管理模式,使团队相较个人管理的优劣对比成为有意义的研究课题。本文以2003—2012年我国全部开放式基金为样本,系统全面地探讨个人和团队两种基金管理模式在投资风格与基金业绩上的差异,以及团队内部结构对团队管理基金的投资风格和业绩的影响。通过以月度收益标准差、前十大证券集中度衡量基金投资风格,及以夏普比率、择时能力、选股能力衡量基金业绩,发现在股票型基金和混合型基金中团队管理比个人管理的基金整体风险低,而团队和个人管理的基金整体业绩上不存在显著差异。针对团队内部结构的分析发现,团队合作年限与股票型基金业绩成正比,但团队合作年限会加重群体极化,使股票型基金风险趋大,但债券型基金风险趋小,同时团队规模和团队合作年限与混合型基金的择时能力呈负相关。     

我国证券投资基金业绩持续性研究——基于参数和非参数方法

基于2007～2010年间的数据,本文利用参数和非参数方法,对我国开放式证券投资基金中的股票型基金、混合型基金和债券型基金的绩效持续性进行了实证分析。结果表明,基于横截面回归的参数检验方法认为,我国的混合型基金业绩具有一定的持续性,而股票型基金与债券型基金的业绩持续性比较微弱。非参数方法中的Fisher精确检验法认为,我国的股票型基金、混合型基金、债券型基金的业绩都不具有明显的持续性。而卡方检验、交叉积比率检验与Spearman秩相关检验则认为我国股票型基金、混合型基金、债券型基金的绩效在特定时段具有持续性。结合参数检验的方法与非参数检验的方法来看,我国混合型基金业绩持续性要好于股票型基金的业绩,而债券型基金业绩持续性相对较差。     

基于参数法的基金业绩分析

本文拟采用基于参数法的研究方法,研究开放式股票型基金的业绩持续性和稳定性。通过实证研究发现,由于持续周期不同,基金业绩的持续性也表现出较大差异。同时,基金业绩与投资风格也有一定相关性。     

开放式股票型基金的业绩持续性分析

本文采用横截面回归和列联表两种方法研究了开放式股票型基金的业绩持续性。截面回归分析表明,考察期是1个月和3个月时,基金的业绩持续性不足。但在较长的考察期内,如半年和1年内,开放式股票型基金业绩具有一定持续性。与之相对的是,基于列联表法的实证结论则显示年度业绩并没有显示出持续性。实证分析表明,在波动巨大的A股市场上,基金风格趋同、投机性很强。这也是基金业绩难以持续的原因。     

我国开放式股票型基金收益:2005-2010

本文整体分析了我国开放式股票型基金2005-2010的收益。实证分析表明基金业绩的评价与比较基准的选择有关,我国基金不存在超额收益,绩效没有持续性。     

我国证券投资基金总体绩效的实证分析——基于总业绩评价理论

本文基于2007—2010年间数据,对我国开放式证券投资基金中的股票型基金、混合型基金和债券型基金的总体绩效进行了比较实证分析。研究发现:各股票基金的业绩表现极不均衡,基金经理的选股能力参差不齐,但选股能力或者择时能力有了明显的提高;各混合型基金的绩效分布都较为接近正态分布;我国债券型基金的业绩表现基本稳定,并没有随着股票市场的大起大落而表现出明显的好与差,其风险收益均大于与市场同风险的投资组合的风险收益,但是这种优势并不太明显。     

基金业绩持续性与择时选股能力的实证研究

以DEA效率为代理指标,通过双向表法和相关性检验的非参数方法,重点考察了基金业绩的持续性特征及其影响因素.通过考察2007～2013年期间我国开放式股票型基金的绩效表现,结果显示基金业绩不具有明显持续性特征,基金经理的择时能力与选股能力均不是持续性的决定性因素.     

基于风险调整收益评估理论的股票型基金绩效实证分析

近年来,开放式股票型基金已经成为机构投资者的重要关注点,在中国资本市场上发挥着不可替代的作用.对于开放式股票型基金的绩效评价成为众所周知的重要课题.本文首先从理论角度介绍了国内关于基金绩效评价的研究,其次借助风险调整的收益评估理论,选取10只股票型基金为样本,对基金的承担风险能力和收益状况进行了分析.     

基于M2指数的我国股票型开放式基金的投资绩效研究

本文引入M2指数测度法对我国股票型开放式基金的投资绩效进行研究.M2指数测度法综合考虑了基金的风险与收益,各股票型开放式基金的M2值排名能为投资者选择基金提供参考.研究结果表明,由于系统风险无法消除,我国股票型开放式基金收益波动与市场波动表现出较强的一致性,不同投资风格的基金对市场波动的敏感程度也有所不同.但是不同投资风格的基金之间并不存在明显的业绩的差别,基金的绩效差别反映的主要是基金的管理水平存在差异.     

投资基金应用金融衍生品的策略研究

股指期货等金融衍生品即将在我国推出,如何应用金融衍生品引起了投资基金的高度关注。本文认为投资基金可以运用金融衍生品来进行替代投资、优化投资、管理市场风险和管理流动性风险,并提出了相应的应用策略。     

Does past performance affect mutual fund tracking error in Taiwan?

This study examines the relationship between fund past performance and manager choice of portfolio risk in Taiwan. Employing the exponential generalized autoregressive conditional heteroscedasticity and linear regression models, the results demonstrate that historically poor average performance does not increase mutual fund tracking error (TE) or portfolio risk. Additionally, yearly tournament behaviour, namely mid-year losers increasing their last-half year TEs, only appears in funds with higher management fees. This implies that managers of high management fee funds actively increase TE in response to poor historical performance, to enable them to beat the market during future months or the second half of the year.     

私募股权投资基金薪酬合约的激励机制研究

利用合约经济学的分析方法研究私募股权投资基金的薪酬合约,我们发现:在不对称信息下创业投资家的道德风险会造成显著的代理成本.并且私募基金管理的代理成本与创业投资家的能力、风险厌恶程度以及私募股权投资基金投资组合的风险正相关;同时我们发现在私募股权投资基金的薪酬合约中引入创业板市场的景气状况作为投资组合收益的基准可显著提高创业投资家的努力激励,并显著降低私募股权投资基金管理的代理成本.     

Individual account investment options and portfolio choice: Behavioral lessons from 401(k) plans

This paper examines how the menu of investment options made available to workers in defined contribution plans influences portfolio choice. Using unique panel data of 401(k) plans in the U.S., we present three principle findings. First, we show that the share of investment options in a particular asset class (i.e., company stock, equities, fixed income, and balanced funds) has a significant effect on aggregate participant portfolio allocations across these asset classes. Second, we document that the vast majority of the new funds added to 401(k) plans are high-cost actively-managed equity funds, as opposed to lower-cost equity index funds. Third, because the average share of assets invested in low-cost equity index funds declines with an increase in the number of options, average portfolio expenses increase and average portfolio performance is thus depressed. All of these findings are obtained from a panel data set, enabling us to control for heterogeneity in the investment preferences of workers across firms and across time.     

Private equity characteristics and performance: An analysis of North American venture capital and buyout funds

The paper investigates the relationship between fund performance and fund characteristics of North American private equity (PE) funds, by analyzing the interactions of fund size, fund sequence, and past fund performance on traditional fund return measures. The empirical evidence is based on both linear and polynomial regressions, on a sample of 345 venture capital (VC) and 411 buyout (BO) funds with vintage year over the period 1995–2010. We document a concave relationship between fund size and performance, persistence in PE performance, as well as a convex relationship between fund sequence and performance. We suggest both the optimal fund size and the optimal fund sequence number. Economic implications for investors and general partners are discussed as well.     

Fund Portfolio Holdings and Affiliated Analyst's Objectivity: Do Equity and Employment Relationship Matter?

The author investigates how the equity relationship between fund company and brokerage firm as well as employment relationship between analyst and brokerage firm affect affiliated fund stock portfolio holding and the affiliated analyst's objectivity. By using the specific data of such equity and employment relationship, the author finds that equity and employment relationship do matter in fund portfolio holdings and analyst objectivity. Specifically, analysts tend to release more optimal ratings on stocks that have been hold by the funds, and the funds tend to significantly reduce the stocks in their portfolio once the analysts have announced high ratings on the stocks. Moreover, the analysts in employment relationships with majority shareholders of funds and with a low reputation reveal worse objectivity. In addition, from the point of abnormal return, analysts in employment relationships with majority shareholders of funds and with a low reputation damage the interests of common investors.     

Optimal asset allocation strategies of university endowment funds

Optimal asset allocation for university endowment funds is very important in USA. The management of endowment funds is challenging due to the need of finding out the balance between providing adequate and stable spending for beneficiaries and growth of the portfolio. In this paper, the author address these allocation constraints in a dynamic framework, in which minimum subsistence levels are introduced in the objective function and derive explicit formulas for the optimal portfolio strategy.     

International diversification and industry-related labor income risk

Do equity markets help diversifying away industry-related labor income risk? This paper reconsiders the hedging role of stock markets by focusing on international equity diversification, rather than domestic asset allocation, and on industry wage, rather than individual labor income. We compare industry-based portfolio holdings to the one that is optimal for an investor endowed with the average home-country labor income. Our results resurrect the role of equities in hedging wage risk by uncovering remarkable heterogeneity across industries within each investing country. Our analysis also delivers insights concerning the role of occupational pension funds in designing optimal portfolios for their members.     

社保基金投资资本市场的收益—风险研究

资本市场为社保基金保值增值提供了基本工具。对1993—2006年中国资本市场运行的实证研究表明,作为风险量度的投资组合标准差每增加1%,可以获得0.221%的预期收益。尽管中国股票市场风险较大,但是,社保基金一定程度地参与股票市场,不仅可以享受经济增长的红利,而且可以取得投资组合分散风险的结果。
