Mutual Fund Performance: Evidence from the UK

This paper uses a large sample containing the complete return histories of 2300 UK open-ended mutual funds over a 23-year period to measure fund performance. We find some evidence of underperformance on a risk-adjusted basis by the average fund manager, persistence of performance and the existence of a substantial survivor bias. Similar findings have been reported for US equity mutual funds. New findings not previously documented for other markets include evidence that mutual fund performance varies substantially across different asset categories, especially foreign asset categories. We also identify some new patterns in performance related to the funds' distance from their inception and termination dates: underperformance intensifies as the fund termination date approaches, while, in contrast, there is some evidence that funds (weakly) outperform during their first year of existence.     

False Discoveries in UK Mutual Fund Performance

We use a multiple hypothesis testing framework to estimate the false discovery rate (FDR) amongst UK equity mutual funds. Using all funds, we find a relatively high FDR for the best funds of 32.8% (at a 5% significance level), which implies that only around 3.7% of all funds truly outperform their benchmarks. For the worst funds the FDR is relatively small at 7.6% which results in 22% of funds which truly underperform their benchmarks. For different investment styles, this pattern of very few genuine winner funds is repeated for all companies, small companies and equity income funds. Forming portfolios of funds recursively for which the FDR is controlled at a ‘acceptable’ value, produces no performance persistence for positive alpha funds and weak evidence of persistence for negative alpha funds.     

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.

Truth in Mutual Fund Advertising: Evidence on Future Performance and Fund Flows

We examine a sample of 294 mutual funds that are advertised in Barron's or Money magazine. The preadvertisement performance of these funds is significantly higher than that of the benchmarks. We test whether the sponsors select funds to signal continued superior performance or they use the past superior performance to attract more money into the funds. Our analysis shows that there is no superior performance in the postadvertisement period. Thus, the results do not support the signaling hypothesis. On the other hand, we find that the advertised funds attract significantly more money in comparison with a group of control funds.     

XBRL、代理成本与绩效水平——基于中国开放式基金市场的证据

从2010年开始,中国证监会强制要求所有基金公司采用XBRL在唯一指定的官方网站上披露年报等信息,同时提供在线XBRL阅读器以方便投资者查阅相关信息。基于此,本文考察XBRL的采用对于开放式基金代理成本及其相关经济后果的影响,研究发现,强制采用XBRL,降低了开放式基金的代理成本,同时提升了开放式基金的绩效水平。研究表明这一新的披露方式,减少了投资者的信息搜索成本以及投资者与基金经理之间的信息不对称,从而促进了投资者作为委托人对于代理人行为的有效监督。     

Investors Do Respond to Poor Mutual Fund Performance: Evidence from Inflows and Outflows

We examine the relation between mutual fund performance and gross flows for a large sample of actively managed U.S. mutual funds. Unlike previous studies that have only examined periods of generally increasing net flows, our sample includes periods of both increasing and decreasing net flows. We find that outflows are related to performance, with investors withdrawing money from poor performers. We also find that outflows and inflows respond asymmetrically to performance, outflows increase more aggressively following poor performance, and inflows increase more aggressively following good performance. Additionally, we find a symmetric performance net flow relation.     

Evaluating Mutual Fund Performance

We study standard mutual fund performance measures, using simulated funds whose characteristics mimic actual funds. We find that performance measures used in previous mutual fund research have little ability to detect economically large magnitudes (e.g., three percent per year) of abnormal fund performance, particularly if a fund's style characteristics differ from those of the value-weighted market portfolio. Power can be substantially improved, however, using event-study procedures that analyze a fund's stock trades. These procedures are feasible using time-series data sets on mutual fund portfolio holdings.     

European Mutual Fund Performance

This paper presents an overview of the European mutual fund industry and investigates mutual fund performance using a survivorship bias controlled sample of 506 funds from the five most important mutual fund countries. The latter is done using the Carhart (1997) 4-factor asset-pricing model. In addition we investigate whether European fund managers exhibit 'hot hands', persistence in performance. Finally the influence of fund characteristics on risk-adjusted performance is considered. Our overall results suggest that European mutual funds, and especially small cap funds are able to add value, as indicated by their positive after cost alphas. If we add back management fees, four out of five countries exhibit significant out-performance at an aggregate level. Finally, we detect strong persistence in mean returns for funds investing in the UK. Our results deviate from most US studies that argue mutual funds under-perform the market by the amount of expenses they charge.     

期末溢价与基金家族策略——来自中国公募基金市场的证据

本文发现中国公募股票基金存在报告期末溢价,且这一现象与基金家族策略有关,是基金家族内部协调基金业绩的新手段。研究发现,基金在季度末比平时有更高的超额收益,且在下一季度初反转。基金重仓股在季度末也有类似的超额收益与反转,表明基金在报告期末拉抬股价从而产生期末溢价现象。进一步研究发现,家族内部规模大、成立时间长和往期业绩好的基金在季度末的溢价现象更严重。这类“高价值基金”与同家族“低价值基金”在季度末的净值收益率之差显著为正,而与不同家族的 “低价值基金”在季度末的净值收益率没有显著差别。此外,我们发现在家族内共同持股现象更严重的基金中,期末溢价更为显著。这些证据表明,基金的期末溢价是基金家族策略的一种新手段,会进一步扭曲基金收益排名,损害投资者利益。     

Mutual Fund Family Size and Mutual Fund Performance: The Role of Regulatory Changes

We examine whether the previously documented positive association between fund family size and fund performance is affected by significant regulatory changes (i.e., Regulation Fair Disclosure (Reg FD), the Global Settlement (GS), and increased scrutiny as a result of trading scandals) that have occurred in the last decade. Using Reg FD as a beginning point for these structural changes, we find that, while fund family size was positively associated with fund performance in the period prior to the regulatory changes, this advantage is significantly weaker in the period subsequent to the regulatory changes. Consistent with the weakened advantage of fund family size in fund performance, we find that the greater stock‐picking skill of larger fund families, measured using the earnings announcement returns of the stocks they trade, also weakened subsequent to the regulatory changes. Using narrower event windows around the regulatory changes, we find that the previously documented superior return of large fund families was partly attributable to selective disclosure. We also find that fund families implicated in the trading scandals experienced a decline in their performance during the scandal period. Finally, we examine the role of large investment banks in providing an advantage to large fund families. Family size was positively associated with the extent to which funds traded in the same direction as forecast revisions by analysts from large investment banks in the period prior to Reg FD and the GS and this association declined significantly after the two regulatory events.     

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.     

Short-Term Persistence in Mutual Fund Performance

We estimate parameters of standard stock selection and markettiming models using daily mutual fund returns and quarterlymeasurement periods. We then rank funds quarterly by abnormalreturn and measure the performance of each decile the followingquarter. The average abnormal return of the top decile in thepost-ranking quarter is 39 basis points. The post-ranking abnormalreturn disappears when funds are evaluated over longer periods.These results suggest that superior performance is a short-livedphenomenon that is observable only when funds are evaluatedseveral times a year.     

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.     

The Persistence of Mutual Fund Performance

This paper analyzes how mutual fund performance relates to past performance. These tests are based on a multiple portfolio benchmark that was formed on the basis of securities characteristics. We find evidence that differences in performance between funds persist over time and that this persistence is consistent with the ability of fund managers to earn abnormal returns.     

On Persistence in Mutual Fund Performance

Using a sample free of survivor bias, I demonstrate that common factors in stock returns and investment expenses almost completely explain persistence in equity mutual funds' mean and risk-adjusted returns. Hendricks, Patel and Zeckhauser's (1993) “hot hands” result is mostly driven by the one-year momentum effect of Jegadeesh and Titman (1993) , but individual funds do not earn higher returns from following the momentum strategy in stocks. The only significant persistence not explained is concentrated in strong underperformance by the worst-return mutual funds. The results do not support the existence of skilled or informed mutual fund portfolio managers.     

Portfolio Manager Ownership and Mutual Fund Performance

This paper examines the association between a mutual fund manager's personal fund investment and mutual fund performance. From a data set of newly released managerial ownership disclosures, I find that fund ownership levels are diverse and, in many instances, quite large. Mutual fund returns are increasing in the level of managerial investment, consistent with personal ownership realigning decision-maker and shareholder interests. Also consistent with the reduction of agency costs, I find that managerial ownership is inversely related to fund turnover. However, there is no evidence of an association between managerial ownership and a mutual fund's tax burden.     

Measuring Mutual Fund Performance with Characteristic-Based Benchmarks

This article develops and applies new measures of portfolio performance which use benchmarks based on the characteristics of stocks held by the portfolios that are evaluated. Specifically, the benchmarks are constructed from the returns of 125 passive portfolios that are matched with stocks held in the evaluated portfolio on the basis of the market capitalization, book-to-market, and prior-year return characteristics of those stocks. Based on these benchmarks, “Characteristic Timing” and “Characteristic Selectivity” measures are developed that detect, respectively, whether portfolio managers successfully time their portfolio weightings on these characteristics and whether managers can select stocks that outperform the average stock having the same characteristics. We apply these measures to a new database of mutual fund holdings covering over 2500 equity funds from 1975 to 1994. Our results show that mutual funds, particularly aggressive-growth funds, exhibit some selectivity ability, but that funds exhibit no characteristic timing ability.
