Costly Search and Mutual Fund Flows

This paper studies the flows of funds into and out of equity mutual funds. Consumers base their fund purchase decisions on prior performance information, but do so asymmetrically, investing disproportionately more in funds that performed very well the prior period. Search costs seem to be an important determinant of fund flows. High performance appears to be most salient for funds that exert higher marketing effort, as measured by higher fees. Flows are directly related to the size of the fund's complex as well as the current media attention received by the fund, which lower consumers' search costs.     

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.     

The Effects of Advertising on Mutual Fund Flows: Results from a New Database

We examine 471,000 mutual fund company advertisements from 1997 to 2003 to study advertising's effect on fund inflows. We find advertising is generally ineffective in attracting inflows but was more effective during the bear market despite smaller advertising expenditures during this time. The top 10 advertisers in our sample were most successful in capturing inflows. These companies generated inflows with mutual fund ads; other companies succeeded when advertising their other products and their brand image. Within a fund family, advertising affects the flagship fund differently than the other funds. Sample firms appeared unable to choose correctly between print and TV ads.     

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.     

Mutual Fund Flows and Cross‐Fund Learning within Families

We develop a model of performance evaluation and fund flows for mutual funds in a family. Family performance has two effects on a member fund's estimated skill and inflows: a positive common‐skill effect, and a negative correlated‐noise effect. The overall spillover can be either positive or negative, depending on the weight of common skill and correlation of noise in returns. Its absolute value increases with family size, and declines over time. The sensitivity of flows to a fund's own performance is affected accordingly. Empirical estimates of fund flow sensitivities show patterns consistent with rational cross‐fund learning within families.     

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.     

Geography,Informal Information Flows and Mutual Fund Portfolios

This paper explores how informal information channels impact mutual fund performance. We measure the strengths of two location‐based information channels: 1) information transfers among fund managers (fund‐fund links) and 2) transfers between managers and the companies in which they invest (fund‐company links). We find that each channel increases investment performance in the absence of the other, but decreases it when acting in combination. Stock selection associated with the presence of one channel, but the absence of the other, earns positive future returns. Our results indicate that the economic benefits of informal information channels depend critically on the nature of their interactions.

Performance Chasing,Fund Flows and Fund Size in Real Estate Mutual Funds

Real estate mutual funds have grown dramatically in number, size, scope and assets under management over the last 15 years, but little assessment is evident. The present study addresses this limitation. Better prior period performance is associated with greater shares of fund inflows for a period. Returns, however, are negatively associated with increased fund flows and fund size. Investors chase past performance limiting fund managers’ ability to optimize investments. Under normal market conditions, but departing from typical mutual fund performance, real estate mutual fund returns generally exceed relevant benchmarks on a before expenses basis and match benchmark returns after expenses. The ability to meet and exceed benchmark returns, however, does not hold during the financial crisis period. Overall, more established funds are shown to have higher returns while fund turnover is not a determinant of returns.

Mutual Fund Managers’ Prior Work Experience and Their Investment Skill

This paper examines the relationship between mutual fund managers’ past professional backgrounds and their portfolio performance using Chinese mutual fund data from 2003 to 2016. We focus on managers with prior work experience either as industry analysts or as macroanalysts. We hypothesize that managers who worked as industry analysts exhibit superior stock picking skills, while managers with a background as macroanalysts time the market better. These hypotheses are supported by the data after controlling for observable fund and manager characteristics. Bootstrap analyses suggest that a significant difference in performance between these two types of managers cannot be attributed purely to luck.     

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.     

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.     

Mutual Fund Performance: An Empirical Decomposition into Stock-Picking Talent, Style, Transactions Costs, and Expenses

We use a new database to perform a comprehensive analysis of the mutual fund industry. We find that funds hold stocks that outperform the market by 1.3 percent per year, but their net returns underperform by one percent. Of the 2.3 percent difference between these results, 0.7 percent is due to the underperformance of nonstock holdings, whereas 1.6 percent is due to expenses and transactions costs. Thus, funds pick stocks well enough to cover their costs. Also, high-turnover funds beat the Vanguard Index 500 fund on a net return basis. Our evidence supports the value of active mutual fund management.     

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)     

Mutual Fund Herding and the Impact on Stock Prices

We analyze the trading activity of the mutual fund industry from 1975 through 1994 to determine whether funds "herd" when they trade stocks and to investigate the impact of herding on stock prices. Although we find little herding by mutual funds in the average stock, we find much higher levels in trades of small stocks and in trading by growth-oriented funds. Stocks that herds buy outperform stocks that they sell by 4 percent during the following six months; this return difference is much more pronounced among small stocks. Our results are consistent with mutual fund herding speeding the price-adjustment process.     

Equity Fund Performance Persistence with Investment Style: Evidence from Korea

Using a comprehensive database on equity funds in Korea, we investigate the performance and performance persistence with investment style employing the Fama and French three-factor model and the Carhart four-factor model. The paper finds that most investment styles in Korea noticeably outperform the passive benchmarks. In addition, positive performance persistence is observed among funds investing in large-cap stocks and stocks of high past performance. Finally, outperformance and positive performance persistence of equity funds are still present in various ranking and postranking horizons. These empirical findings are in sharp contrast with results from earlier studies on markets in developed countries, such as the United States.

Emerging Stars and Developed Neighbors: The Effects of Development Imbalance and Political Shocks on Mutual Fund Investments in China

This paper examines the influence of regional economic development on mutual funds investment decisions. Using fund holdings from 2003 to 2008, we find that Chinese mutual funds that collectively reside in the developed coastal region have the ability to select “star” firms from neighboring inland areas and overweight them in their portfolios. However, they present a clear local bias within the coastal region. Such investment behavior is robust to political interventions. In particular, changes in political climate make mutual funds seek fundamentals like growth prospects and diversification benefits. Overall, economic and political factors significantly influence mutual funds investment decisions in emerging China.     

对冲基金新特点及其对中国资本市场的影响

1997年亚洲金融危机以后,由于人们普遍认为对冲基金是这次危机的罪魁祸首,对冲基金格外受到各国的关注。近几年来,对冲基金表现出了新的特点,随着中国对外开放的扩大,对冲基金必然要影响中国的资本市场。近期看,对冲基金对中国的资本市场不会有太大的影响;从长远看,对冲基金进入中国资本市场是迟早的事情。而对冲基金的运作模式,将对我国金融体制改革的深化和资本市场的发展起到很好的借鉴作用。
