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.     

On Mutual Fund Investment Styles

Most mutual funds adopt investment styles that cluster arounda broad market benchmark. Few funds take extreme positions awayfrom the index, but those who do are more likely to favor growthstocks and past winners. The bias toward glamour and the tendencyof poorly performing value funds to shift styles may reflectagency and behavioral considerations. After adjusting for style,there is evidence that growth managers on average outperformvalue managers. Though a fund's factor loadings and its portfoliocharacteristics generally yield similar conclusions about itsstyle, an approach using portfolio characteristics predictsfund returns better.     

Who Gambles in the Stock Market?

This study shows that the propensity to gamble and investment decisions are correlated. At the aggregate level, individual investors prefer stocks with lottery features, and like lottery demand, the demand for lottery-type stocks increases during economic downturns. In the cross-section, socioeconomic factors that induce greater expenditure in lotteries are associated with greater investment in lottery-type stocks. Further, lottery investment levels are higher in regions with favorable lottery environments. Because lottery-type stocks underperform, gambling-related underperformance is greater among low-income investors who excessively overweight lottery-type stocks. These results indicate that state lotteries and lottery-type stocks attract very similar socioeconomic clienteles.     

Good Stewards, Cheap Talkers, or Family Men? The Impact of Mutual Fund Closures on Fund Managers, Flows, Fees, and Performance

We examine a sample of 125 equity mutual funds that closed tonew investment between 1993 and 2004. We find that funds closefollowing a period of superior performance and abnormal fundinflows. Fund managers raise their fees when they close to compensatemanagers for losses in income due to the restrictions in sizeimposed by the fund closure decision. Managers reopen when fundsize declines. However, they do not earn superior returns afterreopening, suggesting that the fund closure decision does notprovide information about superior fund managers. (JEL G14,G23)     

Performance aspects of Greek bond mutual funds

This paper examines the performance characteristics of Greek bond funds and the impact of fund flows on portfolio returns. The evidence shows that on average bond funds do not offer risk-adjusted profits exceeding the returns of the benchmark index, which is in consistence with the US and international evidence. Returns before fees are slightly superior to the returns of the benchmark index, but when fees are considered they lag considerably. The security selection and market timing skills of fund managers are also tested using both an unconditional and a conditional model to test for the impact of public information variables. We also find that fund flows impact negatively on market timing.     

Portfolio manager home-country culture and mutual fund risk-taking

I find that home-country culture affects portfolio managers’ investment risk-taking and performance. I focus on security value, which measures the degree to which people in a country assign importance to security, safety, and stability. Funds managed by managers from countries with higher security value exhibit lower fund return volatility, trade less frequently, and follow benchmarks more closely. These funds also tend to avoid lottery-type stocks and hence perform significantly better. However, the impact of home-country security value decays as managers spend more time away from their home countries.     

Returns from Investing in Equity Mutual Funds 1971 to 1991

Several recent studies suggest that equity mutual fund managers achieve superior returns and that considerable persistence in performance exists. This study utilizes a unique data set including returns from all equity mutual funds existing each year. These data enable us more precisely to examine performance and the extent of survivorship bias. In the aggregate, funds have underperformed benchmark portfolios both after management expenses and even gross of expenses. Survivorship bias appears to be more important than other studies have estimated. Moreover, while considerable performance persistence existed during the 1970s, there was no consistency in fund returns during the 1980s.     

Fund Manager Succession in Closed-End Mutual Funds

Managing the succession process by the hiring and firing of key executives is one of the important functions of a board of directors. In this research we study successions of fund managers in the closed‐end mutual fund industry. The agency issues inherent in closed‐end mutual funds makes them a unique laboratory for such a study. Our results suggest that while the overall abnormal returns of these manager changes are statistically insignificant, that the returns are more positive for funds with large expense ratios and for funds trading at a discount. We also find the abnormal returns are negatively related to the percentage of inside director stock ownership. Corporate bond funds and international equity funds react more negatively to these announcements than other types of funds. The abnormal returns do not appear to be related to board composition, but board composition does vary across fund type, and may therefore indirectly influence the results.     

Derivative use,fund flows and investment manager performance

Prior literature which examines the use of derivatives by investment managers does not discern between different types of derivative trading strategies. This study is the first to examine and gather data on a particular type of derivative trading strategy undertaken by investment managers. We examine the extent to which equity fund managers use index futures to manage fund flows and the effect this has on their alpha and market timing measures of performance. Our results show that funds that do not use derivatives exhibit lower returns and negative market timing skills when they experience fund flow. The performance of funds that use derivatives, however, is independent of investor’s liquidity demands. In fact, the unconditional performance of the average user fund is statistically equivalent to the performance of the average non-user fund conditional on zero fund flow. Our results provide evidence that derivatives can be beneficial for mutual fund holders under certain conditions.     

Do Managerial Skills Vary Across Fund Managers? Results Using European Mutual Funds

This paper uses stochastic dominance techniques to examine whether managerial skills vary across fund managers in European equity funds. The use of these techniques allows us to compare different investment alternatives in an uncertain setting under very simple assumptions regarding investor behaviour. The results for style-adjusted returns are consistent with varying degrees of managerial skill and cannot be explained by the impact of the choice of style-adjustment procedure, country, fee policy, and fund age, fund size or survivorship bias. This result allows us to conclude that style-adjusted returns may provide a reliable guide for selecting European investment funds.     

Unobserved ties between corporate executives and mutual fund managers

After corporate executives relocate from origin firms to destination firms, only 3.6 percent of mutual fund managers follow the departing executives: they divest from origin firms while initiating investments in destination firms. This phenomenon is more pronounced for those funds that earned superior returns from investments in the origin firms, and that demand more information regarding the destination firms. Further, comigration funds’ holding changes in destination firms more accurately predict cumulative abnormal returns around earnings announcements than do their investments in other stocks and non‐comigration funds’ new investments. Hiring the migrating executives does not improve the destination firms’ operating performance.     

Active management, fund size, and bond mutual fund returns

Conventional wisdom holds that bonds are relatively homogenous investments compared to equities. Consequently, factors that explain variation in returns among bond mutual funds may differ in magnitude from those for equity mutual funds. In this study, a time-series cross-sectional analysis is employed to investigate the relationship between a bond fund's risk-adjusted return and specific fund attributes. Results indicate that a bond fund's past performance does not predict future performance and that bond fund managers are generally ineffective at increasing risk-adjusted returns. However, unlike equity mutual funds, bond mutual funds do appear to enjoy economies of scale.     

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.     

The Determinants and Implications of Mutual Fund Cash Holdings: Theory and Evidence

In this article, I examine the determinants and implications of equity mutual fund cash holdings. In cross-sectional tests, I find evidence generally supportive of a static trade-off model developed in the article. In particular, small-cap funds and funds with more-volatile fund flows hold more cash. However, I do not find that fund managers with better stock-picking skills hold less cash. Aggregate cash holdings by equity mutual funds are persistent and positively related to lagged aggregate fund flows. Aggregate cash holdings do not forecast future market returns, suggesting that equity funds as a whole do not have market timing skills.     

On the concentration of mutual fund portfolio holdings: Evidence from Taiwan

This paper tests the alternative hypotheses of investment selection skills versus overconfidence of equity mutual funds managers in Taiwan. We find that fund holdings’ concentration levels are high and positively related to funds’ risk-adjusted returns in tranquil market periods; however, the concentration levels are low and more negatively related to risk-adjusted returns in turmoil market periods. The time varying concentration-performance relation is not driven by fund size. Our finding implies that fund managers have superior investment selection skills when the market is less volatile, but they exhibit overconfidence when the market is in turmoil, suggesting an investment strategy of shifting from concentrated funds to more broadly diversified funds when market condition becomes worse.     

What style-timing skills do mutual fund “stars” possess?

Recent studies suggest that certain growth-oriented fund managers have substantial skill but do not stipulate the particular skills that they possess. We examine in detail the style-timing abilities of growth-oriented equity mutual funds over the period from 1993 to 2006. We find that an important contributor to the persistent abnormal returns is growth timing, i.e., switching stocks along the value/growth continuum, and that this explains at least 45% of the abnormal returns reported. No other style-timing skills are observed. Our results also demonstrate that it is easy to misidentify growth timing as market timing.     

Mutual Fund Incubation

Incubation is a strategy for initiating new funds, where multiple funds are started privately, and, at the end of an evaluation period, some are opened to the public. Consistent with incubation being used by fund families to increase performance and attract flows, funds in incubation outperform nonincubated funds by 3.5% risk‐adjusted, and when they are opened to the public they attract higher flows. Postincubation, however, this outperformance disappears. This performance reversal imparts an upward bias to returns that is not removed by a fund size filter. Fund age and ticker creation date filters, however, eliminate the bias.     

Alpha and Persistence in Real Estate Fund Performance

This paper investigates whether fund managers investing in the direct real estate market can systematically and persistently deliver superior risk-adjusted returns. The research that has been published has typically focused on the performance of managers trading public real estate securities. Our study draws on a unique data set of commercial real estate funds collated by the Investment Property Databank (IPD) in the United Kingdom, covering up to 280 funds over the period 1981 to 2006. The widespread finding is that very few managers appear to be able to generate excess risk-adjusted returns. Furthermore, there is little evidence of performance persistence in either fund returns or risk-adjusted fund returns.     

On the Industry Concentration of Actively Managed Equity Mutual Funds

Mutual fund managers may decide to deviate from a well‐diversified portfolio and concentrate their holdings in industries where they have informational advantages. In this paper, we study the relation between the industry concentration and the performance of actively managed U.S. mutual funds from 1984 to 1999. Our results indicate that, on average, more concentrated funds perform better after controlling for risk and style differences using various performance measures. This finding suggests that investment ability is more evident among managers who hold portfolios concentrated in a few industries.     

Prudent man or agency problem? On the performance of insurance mutual funds

Active equity mutual funds managed by insurance companies underperform peer funds by over 1% per year. There is no evidence that insurance funds make less risky investments; instead they have lower risk-adjusted returns and their fund flows are less sensitive to performance when they perform poorly. Across insurance funds, those with heavy advertising, directly established by insurers or using parent firms' brandnames, and those whose managers simultaneously manage substantial non-mutual-fund assets, are more likely to underperform. We conclude that insurers' efforts to cross-sell mutual funds aggravate agency problems that erode fund performance.
