我国封闭式基金业绩持续性研究

本文以2001年-2006年所有封闭式基金为样本，研究了我国基金业绩持续性问题，研究发现我国基金业绩在短期内具有持续性，但随着时间推移基金业绩持续性迅速下降。在此基础上，本文认为高收益基金具有较高的系统风险，而且更倾向于采用动量交易策略。     

Relative Performance Evaluation of Mutual Funds: A Non-Parametric Approach

We propose an alternative mutual fund performance index which addresses the benchmark problem and controls for economies of scale in managing mutual funds. We advance a new concept of 'return-cost' efficiency as another important element in evaluating portfolio management, in addition to the mean-variance efficiency concept. Our index based on a non-parametric estimation is shown to be similar to the Sharpe index with multiple slopes (or factors). We have shown that all fund categories, except income funds, have similar average efficiency scores after controlling for economies of scale. Most funds operate in increasing returns to scale and seem to be successful in holding mean-variance efficient portfolios, but unsuccessful in allocating transaction costs efficiently, evidenced by excessive turnovers and loads.     

Dedicated REIT Mutual Fund Flows and REIT Performance

This study examines the effects of weekly and monthly capital flows into the dedicated REIT mutual fund sector on aggregate REIT returns and, simultaneously, the effects of industry-level REIT returns on subsequent REIT mutual fund flows. The dynamic relation between REIT capital flows and returns is estimated using vector autoregression (VAR) techniques. Unlike static regression techniques, our dynamic model produces estimates of the short-run relationships, long-run relationships, impulse response functions, and forecast variance decompositions. We find evidence that REIT mutual fund flows are positively and significantly related to prior returns, while prior REIT mutual fund flows do not significantly influence REIT returns. However, contemporaneous flows do appear to have an initial positive effect, which is partially reversed one period later. The positive contemporaneous effect, however, is the result of unexpected REIT mutual fund flows, while the expected portion is insignificant.     

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。     

Running From a Bear: How Poor Stock Market Performance Affects the Determinants of Mutual Fund Flows

Abstract:  Using a proprietary data set to study how past performance affects the determinants of mutual fund flows for a sample of load fund investors, I provide evidence that the determinants of fund flow depend on market conditions for both redemptions and purchases. Specifically, I show that, for redemptions, relative performance and risk adjusted performance are important determinants during a period of record flows into mutual funds. Conversely, during a period of poor performance, absolute performance becomes much more important and relative performance and risk adjusted performance become less important. For purchases, absolute performance, risk adjusted performance, and most relative performance measures become more important during the bear market.

Taiwanese Mutual Fund Performance Under Different Central Bank of China Monetary Policy Environments

This study examines the performance of mutual funds under different Central Bank of China monetary policy environments in the emerging Taiwan market. To measure monetary policy changes effectively, we exploit changes in the discount rate and further categorize the monetary environment as either restrictive or expansive. We consider a restrictive monetary environment to be a period in which the discount rate rises, whereas an expansive monetary condition is a period in which the discount rate drops. It is found that all mutual funds, both domestic and international funds, exhibit a higher mean return, lower risk, and higher Sharpe and Treynor ratios under expansive monetary policy environments. Regression results show that domestic mutual fund returns are related significantly to local monetary policy. Furthermore, after controlling for the possible effect of macro factors on the association between the monetary policy dummy variable and mutual fund returns, the significant influence of monetary policy on domestic mutual fund returns remains robust. In contrast, changes in U.S. monetary policy stringency, in general, do not affect the performance of either domestic or international mutual funds in Taiwan.     

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.     

Risk-Adjusted Performance of Mutual Funds: Evidence from China

In this article, we evaluate the performance of mutual funds in China between 2006 and 2014. We first estimate time-varying abnormal returns of each mutual fund using an active peer benchmark-augmented factor pricing model. An index of riskiness is then estimated and used to calculate the augmented performance measure (APM). By construction, the APM separates the managerial premium of the fund from systematic risk premium, so it is better than the economic performance measure. The APM incorporates information beyond the first and second moments of the distribution of fund abnormal return; therefore, it is more informative than the Sharpe ratio.     

Termination Risk, Multiple Managers and Mutual Fund Tournaments

This study analyzes the risk-taking behavior of mutual funds in response to their relative performance over the 1992 to 1999 period. Our results show that managers of funds whose performance is closer to that of the top performing funds have greater incentives to increase their portfolios' risk than managers at the top who exhibit a tendency to lock in their positions. The evidence suggests that termination risk imposes a constraint on the risk taking behavior of under-performing fund managers and the winner takes all phenomenon generates a strong incentive for the fund managers to be the top manager. We also analyze the difference in the risk taking behavior of funds managed by multiple managers and single managers.

Family Matters: Rankings Within Fund Families and Fund Inflows

Abstract:  This paper examines the influence of the position of a fund within its family on its subsequent net-inflows. Our empirical study of the US equity mutual fund market shows that reaching a top position within the family leads to large inflows. These inflows accrue beyond those expected, given the performance of the fund in its respective market segment. The effect is much stronger in large families than in small families. We also find that inflows significantly increase if a fund moves into the top positions within its family from one year to another. These results lead to competition within the fund family and to important risk taking incentives for fund managers.

Seasonality, Market Timing and Performance Amongst Benchmarks and Mutual Fund Evaluation

Abstract:  Mutual fund performance is normally measured by comparing results of active management with those obtained by one or several benchmarks that should represent the fund's investment. In this context, this paper examines the effect on mutual fund assessment if a relevant benchmark is omitted. This effect is analysed in three elements of active management: stock selection, market timing, and seasonality. The latter is defined as fund management at specific moments of time with the objective of achieving positive abnormal returns to improve performance. For a sample of Spanish mutual funds, we find that the omission of style benchmarks, particularly that corresponding to small-cap stocks, leads to greater evidence of negative market timing and positive seasonality at year beginning. However, the positive abnormal returns of the seasonality at year end, month end and especially at the beginning of July hold regardless of benchmark omission. The paper therefore also analyses the relation between performance and seasonality, finding that positive seasonality at year beginning and at July beginning improves performance; however, at other moments it implies a possible window dressing strategy in mutual fund management.     

On the Use of Multifactor Models to Evaluate Mutual Fund Performance

We show that multifactor performance estimates for mutual funds suffer from systematic biases and argue that these biases are a result of miscalculating the factor premiums. Because the factor proxies are based on hypothetical stock portfolios and do not incorporate transaction costs, trade impact, and trading restrictions, the factor premiums are either over- or underestimated. We argue that factor proxies based on mutual fund returns rather than on stock returns provide better benchmarks to evaluate professional money managers.     

打造以基金托管人为核心的独立监督实体

我国将资产托管制度引入基金治理的10年来取得了良好效果,但由于发展历史较短及资本市场正处在新兴阶段,托管人的独立监督作用仍然面临质疑.根据托管业的10年实践检验和基金治理的国际经验.本文认为打造以托管人为核心的独立监督实体非常必要.现阶段应采取以托管人为核心,监管机构、交易所等为有效组成部分的模式打造我国的独立监督实体.同时托管人与其他独立监督实体组成部分之间应该建立密切的联系、沟通机制,以形成合力监督.另外,托管人应该以提高独立性为核心,与管理人及相关方建立严格的利益隔离机制;也需要进一步提高独立监督能力,满足独立监督标准.     

封闭式基金折价与管理绩效的实证研究

本文基于管理绩效理论,对我国封闭式基金折价现象进行实证研究。管理绩效理论认为,封闭式基金折价反映了投资者对于基金未来过低的管理能力的理性预期,未来管理绩效越差,折价越大。本文使用了多种基金绩效度量模型,分别采用引入时间哑变量和除去时间均值混合OLS回归方法以及Fama-Macbeth横截面回归方法,验证了折价率和未来管理绩效之间的关系。结果显示,封闭式基金折价和溢价反映了市场对于基金未来管理绩效的预期;当期折价率和未来管理绩效之间存在显著的正向关系,尤其在未来一个季度的时间内;这种关系不受非同步性交易效应和基金异质性的影响。本文同时发现,折价率对于未来管理绩效的解释能力强于过去的管理绩效对于未来管理绩效的解释能力。
