论我国共同基金发展的机遇和挑战——从基金产品发展的角度

我国共同基金经过近十年的跨越式发展已经实现质的飞跃，然而基金产品同质化高，基金投资策略趋同的问题时刻困扰着基金业。本文试图根据海外基金的发展经验，对我国基金产品未来发展提出了几种未来可以走的路径：一是深化发展风格基金，二是投资策略的创新，比如投资策略方面设计一些纯阿尔法基金，贝塔基金。     

基于FF五因子模型的基金投资风格分析模型扩展研究

本文基于FF五因子模型将基金投资风格分类扩展为大-小市值、成长-价值、高-低盈利能力和高-低投资增速四个尺度。实证研究结果表明:(1)相对于FF三因子模型,FF五因子模型对我国基金投资风格及其持续性具有更强的解释力,同时利用不同检验期的数据进行回归分析,可以使扩展的基金投资风格分析模型能够更好地反映基金投资组合的迅速变化,时效性更强,从而能够更好地反映我国基金市场的变化特征;(2)我国基金业整体和基金经理更换分组并没有表现出获取超额收益率的能力,成长型和高盈利能力型投资风格在短期和中期内具有持续性;(3)基金经理未更换分组的情况下能够获取超额收益率,投资风格不具有持续性。     

基金投资风格的极端性与业绩研究

本文首次从综合性视角考察基金投资风格的极端性与其业绩之间的关系。采用投资风格极端性指数和行业集中度作为投资风格的测度,研究发现投资风格的极端性与基金业绩成反比,即投资风格越极端,基金的收益越差。因此,我们建议基金经理在做出投资策略时,应当遵循稳健的投资风格与分散化投资,当发现自己的投资组合风险较大或有明显的行业偏重时,及时做出调整。对于风格极端的基金投资组合,应保持谨慎的态度。     

国内外关于基金投资风格的研究及启示

本文从基金投资风格的种类及划分尺度、识别基金投资风格的方法、基金投资风格与基金业绩、基金投资风格的持续性和中国证券投资基金投资风格的实证研究五个方面，对国内外关于基金投资风格的研究进行了评述，并对相关研究给投资者和基金管理人带来的启示进行了论述。     

国内外对基金投资风格漂移问题的研究

投资风格作为基金投资策略与理念的重要体现,引起越来越多学者的关注,作为其分支领域的投资风格漂移问题的研究也取得了一定成果。文章从基金投资风格识别方法、基金投资风格实证检验、基金投资风格漂移原因和基金投资风格漂移与其业绩关系这几个方面对国内外关于基金投资风格漂移的研究进行了梳理,并对现有研究可能存在的问题提出看法,以期该问题的研究有进一步的发展与突破。

基金经理个人特征对基金绩效的影响及其机理研究

本文引入反映基金经理行为因素的投资风格变量,探讨基金经理个人特征对基金绩效的影响,并分别对牛市和熊市两种不同行情下基金经理个人特征及投资风格与基金绩效之间的相关关系进行分析.在此基础上,将基金极端业绩分布引入模型,对研究进行拓展.研究结果表明:基金经理的性别、学历背景等个人特征能够显著地影响投资风格,而这些个人特征对基金绩效的影响主要通过换手率、持股集中度、行业集中度等投资风格变量来传递;在牛市和熊市两种不同行情下,基金经理个人特征及投资风格对基金绩效和极端业绩分布的影响存在差异.     

银河证券:中小盘股投资价值凸显 诺安中小盘基金表现可期

作为一只风格鲜明的中小盘基金,诺安中小盘股票型基金将投资于具备良好成长潜力及合理估值水平的中小市值股票,在有效控制风险的基础上,力图实现基金资产价值的长期增值。在资产配置上,该基金将以基金资产的60%-95%投资于股票市场,并将其中80%的股票资产投资于中小盘股,以充分分享中小盘股的成长收益。值得一提的是,在投资策略上,诺安中小盘基金采取长期资产配置和短期资产配置相结合     

行业配置的羊群现象——中国开放式基金的实证研究

本文利用2002年至2009年中国市场股票型和混合型开放式基金半年度的完整持仓数据,研究了基金行业配置的相关性。研究发现,相邻两期基金行业需求之间的平均相关系数为32%,说明基金的投资行为在行业层面存在羊群现象;该现象不完全是基金个股的羊群现象在行业层面的表现,也不是全部由基于规模一账面市值比的风格投资行为所驱动。进一步的研究发现,该现象的相关实证特征与相关信号理论的预期相一致。     

基金管理模式对基金业绩、风险及投资风格的影响研究

基金管理模式对基金业绩、风险及投资风格影响的研究,主要是从团队基金管理模式和个人基金管理模式出发,在基金业绩方面,两者没有出现较大的差距,并且运用团队基金管理的模式所面临的风险更小,可以有效保障投资的稳定性和持续性。在本文中通过不同基金管理模式和不同基金类型运用不同管理模式对基金业绩、风险及投资风格造成的影响进行分析,得出结论:无论运用哪一种基金管理模式对最终基金的业绩、投资风格没有显著的影响,但是运用团队的基金管理模式可以更加有效分散投资的风险。     

应合理区分"管理型"与"执法型"税务检查

"管理型检查"与"执法型检查"既互相补充,又有所区别。合理区分两者的性质,对于提高税务检查效率具有重要的现实意义和深远的影响。     

Banking System Bailout-Scandinavian Style

During the Scandinavian banking crisis in the early 1990s, Norway and Sweden chose somewhat different routes to crisis resolution, though both involved government intervention and both proved effective. The Norwegian government injected a hybrid debt-equity form of capital into the largest commercial bank, though only after first extinguishing old equity claims. The Swedish government issued a system-wide debt guarantee and allowed shareholders to maintain their equity stakes, provided they also contributed new equity capital to the banks. In the (single) case where equityholders refused to participate, the government took over the bank and divided it into a “good” and “bad” part, with the latter holding the non-performing loans. The resolution of banking system problems in Scandinavia provides a useful precedent for the recent “bailout” of the U.S. banking system, which, after some initial trial and errors, also involved government ownership of shares in financial institutions. As the author notes in closing, the Scandinavian experience is also relevant for addressing the question of how the U.S. government, having effectively become “owner of last resort” in key financial institutions, should handle its controlling equity stakes.     

Determinants of Equity Style

This paper provides a unifying empirical treatment of propositions explaining equity style cycles with a four-factor model that combines risk factors central to style theory. Tests on style autocorrelations and performance over the period January 1979–December 2004 generally affirm theoretical expectations. We employ cointegration methodology to analyze the stationarity of style covariances and dissect the diversification contributions of styles. We document style diversification gains but discover an asymmetry: value gains are derived from small company stocks while growth benefits come from large stocks. The asymmetry implies portfolios comprised of independent large growth and small value styles since the twin small growth and large value styles are cointegrated and redundant diversifiers. Performance tests show superior performance by the independent styles over the sample period, two equal intertemporal periods, and an extended 5-year period that directly contradicts a risk based explanation. The influence of institutional traders on style trends is also documented. Our findings affirm the predictions of behavioral models and provide more empirical evidence of superior performance unrelated to risk or fundamentals.

Style Drift in Private Equity

Abstract:  We introduce the concept of style drift to private equity investment. We present theory and evidence pertaining to style drifts in terms of a fund manager's stated focus on particular stages of entrepreneurial development. We develop a model that derives conditions under which style drifts are less likely among younger fund managers. We also show ways in which changes in market conditions can affect style drifts, and differences for funds committed to early-stage investments compared to funds committed to late-stage investments. We find some evidence of a positive relation between style drifting and investment performance.     

Style investing and firm innovation

We document that transient, dedicated and quasi-indexed institutional investors exhibit a high degree of within-group heterogeneity with respect to their investment styles (i.e., growth, value, and balanced). We find that growth institutional investors enhance firm innovation in terms of R&D expenditures, R&D intensity, quantity and quality of patents and patent radicalness while value institutional investors impede innovation. Balanced investors have no significant association with innovation. Findings are consistent with style investing literature that growth and value styles are substitutes. Using investment styles, we present evidence that reconcile literature’s mixed findings on how transient and dedicated investors affect R&D and innovation, and why quasi-indexed investors, the largest group among all investors, have an insignificant effect. We also show that the effect of institutional investors depends on the firm’s relative level of innovativeness.
