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。     

Persistence in Equity Fund Performance in Brazil

We examine performance persistence in the large and growing Brazilian equity fund market from 2000 to 2012. We find a significant risk-adjusted spread between a portfolio of top- and bottom-performing funds, which supports the idea that performance persists. This spread remains after controlling for market, size, distress, and momentum risk factors and tends to be larger and more significant for a set of small and retail funds. The spread is mostly driven by the underperformance of the bottom decile of funds, which is consistent with the existence of some fund managers with insufficient skills to recover investment costs.     

证券投资基金的投资风格分析与比较

本文采用基于组合的风格分析方法,对6家中国基金管理公司所管理的30只股票型基金的投资风格进行了实证检验,发现这些股票型证券投资基金的投资风格特征都集中于大盘规模型和风格不一的价值、成长及平衡型,且同一基金管理公司所管理的基金在同一时点的投资风格有趋同现象;此外,还发现有些基金在契约合同中所公布的投资风格与实际检验出的投资风格不尽一致.     

The Performance,Asset Allocation,and Investment Style of International Equity Managers

This paper evaluates the performance of 114 international equity managers over the January 1988–December 1997 period. Performance tests are conducted using Sharpe (1966) and Jensen (1968) performance methodologies. The managers are divided into mutual fund (n=54) and separately managed fund (n=60) investment management categories. Each management category is further divided by foreign and world (global) investment objectives. Three major findings are reported. First, international equity managers, on average, were unable to outperform the MSCI World market proxy during the sample period. However, world managers did perform better than their foreign counterparts. Second, geographic asset allocation and equity style allocation decisions enhanced the performance of international managers during the sample period. Third, separately managed funds outperformed mutual funds during the period studied when mutual fund returns are measured net of management fees. The apparent managed performance advantage abates, however, when mutual fund returns are adjusted to include management fees. Thus, we find no significant difference in the performance of the management categories when returns are measured gross of fees.

Performance Manipulation and Fund Flow: Evidence from China

In this paper, we assess the relation between fund flow and fund returns in China's open-ended fund industry. Analyzing quarterly data from the period January 2005-December 2012, we construct a simultaneous equation model that captures the endogeneity of current and past returns and flows and find that contemporaneous returns have a key role in determining fund flows. We then estimate the fund performance "manipulation degree" to further investigate the performance manipulation effect on fund flows. We find that manipulated funds can attract an additional flow of money and that, notably, individual rather than institutional investors are more likely to be deceived by manipulative behavior.     

基金投资风格漂移及其对基金绩效的影响研究

本文选取一轮完整行情为研究期间，并将其划分为牛市和熊市两个子期间，采用Sharp（1992）提出的基于收益率的投资风格分析法确定基金在两个子期间的实际投资风格，将动态的实际投资风格和宣称的投资风格进行比较，对整个研究期问的“风格漂移”现象进行了研究。在此基础上，考察了“风格漂移”对整个研究期问基金绩效的影响。研究发现，发生明显“风格漂移”的基金绩效要优于未明显发生“风格漂移”基金的绩效。     

Closed‐End Fund Discounts and Expected Investment Performance

This article provides empirical support for the theory that closed‐end fund discounts reflect expected investment performance. Evidence is presented to explain how equity closed‐end fund initial public offerings (IPOs) can sell at a premium when existing funds sell at a discount and why the initial IPO premiums decay after the IPO. Relative premium decay data are presented. Tests on (1) the relation between relative premium changes and investment performance following IPOs, (2) relative premium mean‐reversion following management changes, and (3) net redemptions following closed‐end fund open‐endings for funds trading at pre‐open‐ending announcement discounts individually support and collectively strongly support the theory.

Long-Run Performance Persistence of Investment Funds

This article analyzes the long-run persistence of returns and risk of investment in the assets of money, bound, and stock funds recorded on the Polish market in 2000–12. Portfolios of safe, hybrid, and stock classes are formed on the basis of tested funds. The persistence of returns and the Sharpe ratio are investigated in rolled five-year sub-periods, with one year step. Also, persistence in performance is assessed using classic CAPM and Fama and French models, which allow for evaluating management skills. We find the occurrence of the Sharpe ratio long-run persistence of money and bound funds. The study does not explicitly show long-run persistence in hybrid and stock fund portfolios. The CAPM and Fama and French models simulations of returns on stock and hybrid funds indicate varying management skills during five-year periods.     

基金投资风格的持续性研究:原因与结果

Characteristic Factors and Fund Evaluation in Korea

Factors that govern common variations in equity returns in Korea are identified and the authors examine whether they are priced. Size and the ratio of book value to price turn out to be the determinants of common variations, and these variations appear to be priced. The momentum factor shows mixed results depending on the samples, while macroeconomic factors consistently fail to group stocks in any meaningful manner. These factors are utilized to assess the performance of the retail equity funds. Characteristic-based performance analysis reveals that high risk-adjusted excess returns are accompanied by high selection and timing abilities of fund managers. Risk-adjusted returns are more persistent than unadjusted returns.

Ethical Unit Trust Financial Performance: Small Company Effects and Fund Size Effects

Recent papers which have examined unit trusts have controlled either for a 'fund size effect' or for the 'small firms effect' in the investment portfolio. The contribution of this paper is an analysis of the 'small firms effect' whilst simultaneously controlling for the 'fund size effect'. We show that the ethical unit trusts have significantly greater exposure than general unit trusts to the 'small firms effect', and that net of this there is no significant evidence of over or under performance by ethical trusts using an adjusted Jensen measure. Using two cross-sectional approaches, we demonstrate that whilst a 'small firms effect' has a role to play in explaining unit trust performance, fund size is not correlated with the financial performance of unit trusts. This cross-sectional analysis also provides some evidence that ethical unit trusts may perform less well than general unit trusts.     

Consistency of UK Pension Fund Investment Performance

Transition matrix techniques are used to relate the past and present performance of pension fund portfolios. In particular, funds are ranked to study the tendency of portfolios to remain in the same quartile of the ranking as they were in the previous period. For raw returns, funds in both of the top quartiles are found to be more likely to remain in the same quartile than would be expected by chance. This result can be taken as limited evidence for the consistency of performance. Similar systemic effects are observed on a risk-adjusted basis. There appears to be clear evidence that some fund managers can offer a degree of consistent good performance.

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.     

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.

Mutual Fund Performance: Measurement and Evidence1

The paper provides a critical review of empirical findings on the performance of mutual funds, mainly for the US and UK. Ex‐post, there are around 0‐5% of top performing UK and US equity mutual funds with truly positive‐alpha performance (after fees) and around 20% of funds that have truly poor alpha performance, with about 75% of active funds which are effectively zero‐alpha funds. Key drivers of relative performance are, load fees, expenses and turnover. There is little evidence of successful market timing. Evidence suggests past winner funds persist, when rebalancing is frequent (i.e., less than one year) and when using sophisticated sorting rules (e.g., Bayesian approaches) ‐ but transactions costs (load and advisory fees) imply that economic gains to investors from winner funds may be marginal. The US evidence clearly supports the view that past loser funds remain losers. Broadly speaking results for bond mutual funds are similar to those for equity funds. Sensible advice for most investors would be to hold low cost index funds and avoid holding past ‘active’ loser funds. Only sophisticated investors should pursue an active ex‐ante investment strategy of trying to pick winners ‐ and then with much caution.
