基于风格层面的开放式基金反馈交易行为的实证研究

文章通过结合Sharpe模型的参数构造一个基于风格层面的基金反馈交易检验模型,对我国在2004年之前成立的开放式股票型基金的反馈交易行为进行实证研究,结果发现：基金普遍采取正反馈交易策略,价值型基金比成长型基金具有明显的正反馈交易特征;在熊市时期,债券型基金的正反馈交易特征最为突出;在牛市时期,成长型基金和债券型基金则表现出明显的负反馈交易特征;历史业绩突出的基金更容易在随后时期内采取正反馈交易策略,这种策略在熊市中会恶化业绩,而在牛市中往往会提高其随后的业绩。     

Information content of prior period mutual fund performance rankings

This paper examines the relationship between prior and subsequent period performance rankings for all domestic equity mutual funds followed by Morningstar over the period 1976–1992. Evidence of statistically significant persistence in relative performance was detected in the full sample during the period 1980–1992. However, further examination revealed that persistence in mutual fund performance was no longer evident when the full sample was partitioned by investment objective. In this context, prior period mutual fund performance provides minimal insight into subsequent period performance and, therefore, is of little value in the mutual fund selection process.

运用面板模型,将交易策略指标纳入Sharpe指数多因素门限模型,分别考察在前期Sharpe指数为正和为负的情况下,惯性和反转交易策略对基金绩效的影响。对2006年第一季度至2010年第三季度中国开放式基金面板数据的分析表明:惯性策略在总体上会对投资绩效产生负面影响,而反转交易策略对投资绩效的影响则始终是不显著的。     

Measuring the financial and social performance of French mutual funds: A data envelopment analysis approach

Socially responsible investors pursue both financial and non-financial goals. In this paper, we attempt to assess the performance of French socially responsible mutual funds (SRMFs). We consider the data envelopment analysis (DEA) approach, which allows us to assign a unique efficiency score while combining financial and social characteristics, using various combinations within different types of risk (total risk, market risk, and downside risk). We report the list of funds found to be DEA efficient using various output-oriented models. We also compare our obtained results with the traditional and modern measures used in the literature (Sharpe, Treynor, and the information ratio). We contribute to the literature by testing the validity of the DEA methodology in the financial context. The findings have important implications for fund selection processes and would be mainly of interest to investors and fund managers who integrate environmental, social, and governance criteria into their investment choices.

Harmony,Justice, Confusion,and Conflict in Family Firms: Implications for Ethical Climate and the “Fredo Effect”

In this study, we analyze the financial performance and the managerial abilities of religious mutual fund managers, implementing a comparative analysis with conventional mutual funds. We use a broad sample, free of survivorship bias, of religious equity mutual funds from the US market, for the period from January 1994 to September 2010. We build a matched-pair conventional sample in order to compare the results obtained for both kinds of mutual fund managers. We analyze stock-picking and market timing abilities, topics widely neglected for the specific case of religious mutual fund managers. We also study style timing abilities. As far as we are aware, this aspect has not been studied previously for religious mutual fund managers. Our results indicate that religious mutual fund managers underperform both the market and their conventional counterparts. This result is driven by negative stock-picking ability which could be generated by excluding “Sin” stocks from their portfolios. Moreover, they are not able to time the market or any of the following styles: size, book-to-market, and momentum.     

Market penetration strategies and the fee–performance relationship: the case of Spanish money mutual funds

This article shows that market penetration strategies are common practice during the product introduction stage in the money mutual funds in Spain. During this stage there is no relation between fees and performance because this strategy is optimal. In order to analyse this relationship during the other stages of the product life cycle, funds under three years old were omitted from the analysis. Among the remaining funds, those with the highest fees are found to present a higher gross return than the low-fee funds, although the difference is not statistically significant. Nevertheless, in terms of net returns, low-fee funds are observed to stochastically dominate high-fee funds for any risk-averse investor. These findings hold for any managerial skill level or segmentation by the mutual fund family type.     

The Ethical Mutual Fund Performance Debate: New Evidence from Canada

Although the academic interest in ethical mutual fund performance has developed steadily, the evidence to date is mainly sample-specific. To tackle this critique, new research should extend to unexplored countries. Using this as a motivation, we examine the performance and risk sensitivities of Canadian ethical mutual funds vis-à-vis their conventional peers. In order to overcome the methodological deficiencies most prior papers suffered from, we use performance measurement approaches in the spirit of Carhart (1997, Journal of Finance 52(1): 57–82) and Ferson and Schadt (1996, Journal of Finance 51(2): 425–461). In doing so, we investigate the aggregated performance and investment style of ethical and conventional mutual funds and allow for time variation in the funds’ systematic risk. Our␣Canadian evidence supports the conjecture that any␣performance differential between ethical mutual funds and their conventional peers is statistically insignificant.      

Gold price risk and the returns on gold mutual funds

A model is presented for estimating the theoretical gold price elasticity of the value of mutual funds investing in gold mining companies. The theoretical elasticity shows that if the funds invest in companies whose assets are comprised primarily of operating gold mines, then the return of an investment in the fund will be at least as great as an investment in gold (i.e., the gold price elasticity of the gold fund is greater than 1). Empirical tests of the above propositions are presented. Empirical tests also show, however, that the gold mutual funds contain a substantial amount of risk which is not explained either by market risk or gold price risk. Accordingly, gold mutual funds and gold bullion do not bring identical risks to an investor's portfolio.     

Pricing of Mutual Fund Services in Retirement Plans: Evidence from Open-End Equity Funds

Management fees of mutual funds are more costly to investors than is often realized. Moreover, research indicates that in many cases, the fees are not related to performance, contrary to what might be expected from an efficient market. This study uses sample data to illustrate the consequences of inefficiency to an individual investor. It then turns to an empirical examination of the determinants of the ratio of management fees to total assets (MER), investigating market concentration, fund performance, and non-performance characteristics as explanatory variables. All of these classes of variables contributed to the variation of MERs . JEL Classification G23     

Mode of entry mode into a foreign market: the case of U.S. mutual funds in Canada

U.S. mutual fund companies offer funds in Canada through two channels: foreign direct investment or trade in advisement services. The total value of U.S.-controlled funds amounts to 18% of the Canadian equity fund market. This paper investigates how the fund-level and firm-level characteristics affect the channel used to enter the Canadian market. Empirical results indicate that the funds offered through FDI are not especially successful in the U.S. market but are associated with dominant companies, whereas the funds offered through trade in advisement services are highly successful in the U.S. market and are from companies with relatively few successful funds.     

The Use and Abuse of Mutual Fund Expenses

Prior research shows that mutual fund investors are often aware of up-front charges like sales loads, but they are less mindful of annual operating expenses, even though both types of fees lower overall performance. This study documents the historical trend and recent abuse of annual mutual fund expenses. As the industry becomes more adept at segmenting customers by level of investment sophistication, we claim that load mutual fund companies take advantage of this ability and charge higher expenses to their target customer: the less-knowledgeable investor. No-load fund companies, which tend to attract the more sophisticated investor, offer lower expenses. For example, over 2000–2004 the average annual expense ratio of load equity funds was 50 basis points higher than no-load equity funds. We show evidence of this widening cost disparity since the early 1990s among new and existing equity, bond, and index funds. We also document a growing abuse of sales distribution or 12b-1 fees among funds that are closed to new investors, almost all of which are load funds. Thus, load fund investors are more susceptible to paying higher expenses and receiving lower returns over time. Todd Houge is an Assistant Professor of Finance at the University of Iowa.

The Investment Performance of Socially Responsible Investment Funds in Australia

Interest in the notion of the possible financial sacrifice suffered by socially responsible investment (SRI) fund investors for considering ethical, social and environmental issues in their investment decisions has spawned considerable academic interest in the performance of SRI funds. Both the Australian and international research literature have yielded largely mixed results. However, several of these studies are hampered by methodological problems which can obscure the significance of reported results, such as the use of small sample sizes, inconsistencies in the time frames selected to analyse performance and different modelling frameworks used to estimate investment returns. This study attempts to redress some of these issues by investigating the returns performance of 89 ethical funds in Australia over the period 1986–2005. Using a multi-factor CAPM model [Fama, E. F., and K. R. French (1996) J. Finance 51(1), 55] (which controls for factors such as size, book-to-market value and momentum) we find that ethical funds significantly under-perform the market in Australia, particularly in the most recent 5 years of our sample period (2000–2005). Risk adjusted returns (using Jensen’s alpha) indicate that average annual underperformance is around 1.52% in the 2000–2005 period for our sample and .88% over the whole sample period. Our results contrast with many previous studies (both Australian and international), which have not found statistically significant differences in the performance of ethical funds relative to market benchmarks and/or a matched sample of conventional funds.

Management structure and the performance of funds of mutual funds

A rapidly growing mutual fund category is funds of funds (FOFs) which invest in other mutual funds instead of individual securities. This study reports on FOFs' characteristics and performance relative to traditional equity mutual funds and finds that FOFs compare favorably. FOFs with identified managers outperform their unidentified counterparts, and FOFs that invest in-family outperform both traditional equity funds and those FOFs investing out-of-family. Finally, replicating FOFs' holdings can be prohibitively expensive since they commonly hold funds with high minimum initial investments, closed funds and/or funds that are restricted to a particular investor type.     

On the failure of mutual fund industry regulation

Mutual funds grant retail investors access to professional asset management and facilitate exposure to financial markets. The academic literature and regulators have traditionally focused on issues such as portfolio diversification, performance, liquidity, and management fees in attempts to analyze and improve market efficiency. Scarce attention has been paid to market risk management. There is unanimity on this issue throughout the world. The lack of regulatory attention creates a gap, which is partially covered by mutual fund rating agents and asset management analysts. Those agents base their ratings on various rating methodologies — which engenders a wide array of difficulties, especially for retail investors. We employ proprietary data on historic mutual fund ratings in Israel and show that retail investors do not necessarily benefit from this diversity of opinions. Furthermore, we find that the voluntary implementation of quantitative risk measurement techniques by certain mutual funds tends to be associated with fewer outflows and greater inflows in these funds. Interestingly, the application of (backward-looking) value-at-risk analysis is associated with fewer outflows, while (forward-looking) stress-testing techniques are associated with greater inflows. Given the similarity of mutual fund industry environments across the globe, our results have worldwide applicability.     

Managed commodity funds

The performance of managed commodity fund investments during the years l982 through 1996 is examined, both as stand-alone investments and as assets in diversified stock and bond portfolios. Nine stylized commodity fund investments are examined: randomly-selected, single-CTAs, pool, and fund portfolios; equally weighted market portfolios (EWMPs) of CTAs, pools, and funds; and value-weighted portfolios (VWMP) of CTAs, pools, and funds. Further, two subperiods are examined: 1982–1988 and 1989–1996. Based on an analysis using Sharpe ratios as the performance criterion, several types of managed commodity funds make both good stand-alone investments and good portfolio assets; an EWMP of CTAs and a VWMP of pools receive the highest ranking among the alternative commodity fund investments. It is also shown that commodity indexes are not a substitute for a managed commodity fund investment. A number of issues warrant further study: Can investors still earn consistently attractive risk-adjusted returns on managed commodity fund investments if they do not hold diversified portfolios of CTAs and pools? Also: How can such high speculative returns be earned in efficient commodity markets? And: Are CTA and pool returns high because commodity fund managers have superior trading skill? An important issue for future research is to determine whether in fact CTAs do possess such skill. © 1999 John Wiley & Sons, Inc. Jrl Fut Mark 19: 377–411, 1999

Increasing returns: Competing for customers in the global market

This paper discusses emerging, increasing returns notions, comparing it to the diminishing returns model of the industrial era, with the consequent implications for the global manager. Increasing returns, it is argued, comes from a different set of management premises: capitalising on the time value of individual customers in new “market spaces”, rather than from making and moving more “things” in traditional product/market categories; leveraging intangibles, abundant and infinite, which increasingly deliver the value to customers; and sharing markets, resources and technologies with others in new “competitive spaces”, rather than adopting proprietary behaviour, in order to get critical market mass and lock in. These premises, if consciously managed and translated into strategy, the paper argues, lead to an accumulating advantage and disproportionate returns for corporations.     

MUTUAL FUND PORTFOLIO CHOICE IN THE PRESENCE OF DYNAMIC FLOWS

We analyze the implications of dynamic flows on a mutual fund's portfolio decisions. In our model, myopic investors dynamically allocate capital between a riskless asset and an actively managed fund which charges fraction‐of‐fund fees. The presence of dynamic flows induces “flow hedging” portfolio distortions on the part of the fund, even though investors are myopic. Our model predicts a positive relationship between a fund's proportional fee rate and its volatility. This is a consequence of higher‐fee funds holding more extreme equity positions. Although both the fund portfolio and investors' trading strategies depend on the proportional fee rate, the equilibrium value functions do not. Finally, we show that our results hold even if investors are allowed to directly trade some of the risky securities.     

Are socially responsible exchange-traded funds paying off in performance?

This study examines the Socially Responsible (SR) exchange-traded funds (ETFs) by comparing their risk-adjusted performance with a matched group of conventional ETFs in the U.S. equity market. In contrast to prior studies that focus on actively managed mutual funds, we find that the risk-adjusted returns of SR ETFs are significantly lower than those of conventional ETFs during the 2005–2020 period. Such underperformance is only observed in non-crisis periods but not in economic crisis periods (i.e., the 2020 pandemic recession and 2008 financial turmoil). We attribute the observed underperformance of SR ETFs during the non-crisis periods to their limited diversification of unsystematic risks resulting from various negative or positive screens employed in the funds. We also find that net fund flows of the SR ETFs are less sensitive to past negative performance than are conventional fund flows. Collectively, our findings suggest that, instead of seeking wealth maximization, socially conscious investors may choose SR ETFs to gain non-economic utility.
