Investing in mutual funds: the determinants of implied and actual net cash flows

Estimating the fund investors’ demand plays an important role in the mutual fund management. In this line, mutual fund demand can be measured as the total net cash flows experienced by the fund during a period. Due to a lack of the data for inflows and outflows in some countries and databases, many authors estimate the net cash flows using fund size and return information. This rough measure, although being a good approximation, implicitly assumes an error in its calculation. For a sample of 2985 US open-end funds, we find evidence that estimating this implied fund flows, the error generated is higher for smaller funds, funds with higher returns, and for those experiencing higher levels of inflows or outflows. This lack of precision leads to a distortion in the estimation of the effect of some determinants on the mutual fund demand, especially when longer periods are considered when constructing the net cash flows.     

Smart fund managers? Stupid money?

Abstract .  We develop a model of mutual fund manager investment decisions near the end of quarters. We show that when investors reward better performing funds with higher cash flows, near quarter-ends a mutual fund manager has an incentive to distort new investment toward stocks in which his fund holds a large existing position. The short-term price impact of these trades increase the fund's reported returns. Higher returns are rewarded by greater subsequent fund inflows which, in turn, allow for more investment distortion the next quarter. Because the price impact of trades is short term, each subsequent quarter begins with a larger return deficit. Eventually, the deficit cannot be overcome. Thus, our model leads to the empirically observed short-run persistence and long-run reversal in fund performance. In doing so, our model provides a consistent explanation of many other seemingly contradictory empirical features of mutual fund performance.     

Political Pressure or Rent Seeking? The Role of Mutual Funds in China's Split Share Structure Reform

In this paper, we provide further evidence on the role of mutual funds in China using the split share structure reform as an experiment. We find no supportive evidence for the political pressure hypothesis of Firth et al. (2010), but provide a set of unique results that are consistent with rent‐seeking behaviour by mutual funds. In addition, fund‐level governance can weaken the negative relationship between compensation ratio and fund ownership. Finally, we document a specific form of private benefits that can contribute to rent‐seeking behaviour by mutual funds.     

Information Sharing within the Networks of Delegated Portfolio Managers: Evidence from Plan Sponsors and Their Subadvisers

The authors study information sharing among delegated portfolio managers through networks connected by investment mandates between plan sponsors and their subadvisers. Specifically, they identify similarity in returns, holdings, and trading between mutual funds operated by subadvisers, and test whether such similarity is stronger when two funds share a mandate network. The authors find evidence consistent with information sharing among these delegated portfolio managers. A mutual fund on average shares more similar returns, holdings, and trading with funds in subadvisory mandate networks than with funds outside the networks. Preliminary evidence suggests that information about both general investment styles and individual firms is transferred within mandate networks.     

Risk aversion and portfolio allocation to mutual fund classes

The major factors affecting fund flows allocated to a range of mutual fund classes bearing different risk–return profiles are studied. The flexible functional form of the Almost Ideal Demand System (AIDS) is applied to identify the major drivers of Greek investors' demand patterns for equity, bond, balanced and money market funds, given the strong growth rates of the domestic fund market and the economy's latest entry into the EMU. An increase in household expenditure is shown to have a positive impact on mutual fund flows. An adverse price impact, however, may erode budget benefits towards a fund class, as the price factor appears to be important. The cross-price effects provide insight on complementarity and substitutability among the mutual fund classes. Variations in investors' risk aversion attitudes affect demand for mutual funds and can result in asset reallocation between the asset classes. The conclusions have useful policy implications particularly to asset fund management and portfolio allocation strategies and can be compared with established mutual fund markets.     

Market states and disposition effect: evidence from Taiwan mutual fund investors

We study the disposition effect across market states in the context of mutual fund investors in Taiwan. Using mutual fund data at the fund and individual levels during July 2001 to October 2008, we find that the disposition effect varies across market states. Our results suggest that investors redeem their mutual fund units more under a bear market than a bull market when they have extreme capital losses. When investors have moderate capital gains, they are less active in redeeming their mutual fund units under a bull market relative to a bear market. Under a neutral market, investors actively redeem mutual fund units in both winner and loser mutual funds except when they have extreme capital losses. Thus, disposition effect is not uniform; it varies by market condition. In addition, the disposition effect phenomenon also exists for Taiwan mutual fund investors as well. Our findings are robust to aggregate and individual investor levels.     

Irrational Mutual Fund Managers: Explaining Differences in Their Behavior

Documenting the disposition effect for a large sample of mutual fund managers in the United States, we find that stock-level characteristics explain the cross-sectional variation of the effect. The disposition effect, which is the tendency to sell winner stocks too early and hold on to loser stocks for too long, is more pronounced for fund managers who invest in stocks that are more difficult to value. Using different measures of stock and market uncertainty, we show that mutual fund managers display a stronger disposition-driven behavior when stocks are more difficult to value. We also find that the level of the disposition effect is monotonically increasing with the level of systematic risk (i.e., beta). In addition, we document that the trading behavior of mutual fund managers is partly driven by attention-grabbing stocks (dividend-paying stocks). Overall, our results suggest that stock-level uncertainty and trading of attention-grabbing stocks amplify the disposition effect and that differences in the effect can be explained by mutual fund managers' investment styles. Given that mutual funds hold a large fraction of the U.S. equity market, our findings add to the ongoing discussion whether professional investors can create stock mispricings and shed new light on market efficiency.

Revisiting the Lemons Market

This article extends the standard competitive adverse selection model by allowing for qualitatively different information structures of agents on the informed side of the market. Using the stylized framework of the market for used cars, we examine the welfare properties of equilibria under the assumption that a fraction of the sellers remains uninformed about a parameter that is relevant for their own transaction. Whether market performance increases or decreases in the number of uninformed sellers is shown to depend on (1) the potential gains from trade in the market and (2) the average quality of the sellers' information structure.     

The Relationship between Australian Mutual Fund Fees and Risk‐Adjusted Performance in Differing Economic Conditions

We find that Australian mutual fund investors should avoid high fee funds as these funds generate relatively low after‐fee risk‐adjusted returns both unconditionally and in weak economic conditions. This result is different from some of the previous findings which showed that US mutual funds with relatively high expense ratios may generate relatively higher risk‐adjusted returns during recessions relative to non‐recessions, although their unconditional alphas may be negative. We find some support for the Glode hypothesis in surviving Australian wholesale funds. High‐fee surviving Australian wholesale funds perform relatively strongly in both weak economic conditions and unconditionally. High‐fee funds in other types of Australian mutual funds generally do not perform strongly either in weak economic conditions or unconditionally. Amongst low‐fee funds, we commonly find that those that perform well unconditionally and well in weak economic conditions do charge more than those that perform well unconditionally and poorly in weak economic conditions. Amongst low‐fee funds, it is often true that those that perform poorly unconditionally but well in weak economic conditions can charge more than those that perform poorly unconditionally and poorly in weak economic conditions.     

Average drawdown risk reduction and risk tolerances

We investigate the effects of average drawdown risk reduction on US mutual funds. Due to numerous evidence of the asymmetric distribution of portfolio returns, the asymmetric risk measures have extensively been used in risk management during the recent decades with extensive usages on the n-degree lower partial moment (LPM) methodology. Unlike the previous literature, we use the n-degree average drawdown risk measure, which is a special case of n-degree LPM, to empirically investigate the impacts of n-degree average drawdown risk reduction on the risk tolerances generated by the US mutual funds.The evidence shows that skewness does not impose any significant problem on the n-degree A-DRM model. Moreover, the effect of changing the tolerances of average drawdown risk in the n-degree A-DRM models is a reduction in the fund returns. The n-degree CA-DRM optimization model reduces investors׳ risk more than other models. Thus, the A-DRM can be accommodated with risk-averse investors׳ approach. The efficient set of mean–variance choices from the investment opportunity set, as described by Markowitz, shows that the n-degree CA-DRM algorithms create this set with lower risk than other algorithms. It implies that the mean–variance opportunity set generated by the n-degree CA-DRM creates lower risk for a given return than covariance and CLPM.     

Do mutual fund flows affect the French corporate bond market?

We study whether investors’ withdrawals from mutual funds affect corporate bond prices. As mutual funds have become major players in the financial markets, they are likely to exert downward pressures on asset prices when facing investors’ redemptions, particularly in the less liquid markets such as corporate bonds. We use a novel dataset on the French bond funds and show that both flows in and out of mutual funds lead to a significant effect on the corporate bond yields. This effect is asymmetric as redemptions provoke a change in yields of greater magnitude than inflows. Moreover, all corporate bonds are not equally affected by investors’ withdrawals from funds: The more a bond is detained by funds, the higher the impact of redemptions on its yield. These three results are robust to various changes in econometric specifications.     

The Elephant In The Ground: Managing Oil And Sovereign Wealth

One of the most important developments in international finance and resource economics in the past twenty years is the rapid and widespread emergence of the $6 trillion sovereign wealth fund industry. Oil exporters typically ignore below-ground assets when allocating these funds, and ignore above-ground assets when extracting oil. We present a unified stylized framework for considering both. Subsoil oil should alter a fund’s portfolio through additional leverage and hedging. First-best spending should be a share of total wealth, and any unhedgeable volatility must be managed by precautionary savings. If oil prices are pro-cyclical, oil should be extracted faster than the Hotelling rule to generate a risk premium on oil wealth. Finally, we discuss how our analysis could improve the management of Norway’s fund in practice.     

WHY HAVE U.S. HOUSEHOLDS INCREASINGLY RELIED ON MUTUAL FUNDS TO OWN EQUITY?

U.S. households have increasingly used mutual funds to own equity outside of retirement accounts owing to two developments. The first is a decline in equity mutual fund loads, which are negatively correlated with stock ownership rates, which have doubled owing to greater ownership through mutual funds. The second is improved confidence in future family finances. Both effects are consistent with recent models of equity participation, in which lower asset transfer costs and lower income risk induce equity investing by middle‐income households, who—in practice and owing to diversification considerations—are more likely to indirectly hold stocks through mutual funds.     

The Role of Market Sentiment in Asset Allocations and Stock Returns

Abstract

The authors investigate the role of mutual fund flows in incorporating market sentiment into asset prices. They show that retail investors adjust their investments among mutual fund categories in response to changes in market sentiment. Consistent with sentiment-induced price pressure through fund flows, they further find that firms favored by mutual funds, such as large-cap, dividend payers, and firms with high institutional ownership are sensitive to market sentiment. The authors construct a pricing factor representing sentiment risk and find that the sentiment factor is significant in standard asset pricing models and robust to various sorting procedure.     

Does past performance affect mutual fund tracking error in Taiwan?

This study examines the relationship between fund past performance and manager choice of portfolio risk in Taiwan. Employing the exponential generalized autoregressive conditional heteroscedasticity and linear regression models, the results demonstrate that historically poor average performance does not increase mutual fund tracking error (TE) or portfolio risk. Additionally, yearly tournament behaviour, namely mid-year losers increasing their last-half year TEs, only appears in funds with higher management fees. This implies that managers of high management fee funds actively increase TE in response to poor historical performance, to enable them to beat the market during future months or the second half of the year.

On causality in the size-efficiency relationship: the effect of investor cash flows on the mutual fund industry

One of the perceived advantages in mutual fund management is the presence of economies of scale resulting from fund size. This article analyses the impact of mutual fund cash flows on the relation between size and performance, demonstrating that performance determines asymmetric variations in fund assets, particularly in mutual equity funds. Therefore, the more efficient funds generate broad enough cash flow entry that increases the relative size of the fund, leading to an implicit and positive relation between size and performance. So, if the average size over the period sample is used as a measure of size, such a relation would be biased. When the initial size is used, this bias is avoided and, in general, an insignificant relation is found between size and performance. These results are controlled by mutual fund costs using gross returns to estimate performance. The evidence is robust, and shows only weak evidence of a negative relation between size and performance for the balanced funds that is driven by a low positive relation between costs and size; precisely, the contrary that is expected from the hypothesis of the presence of economies of scale.     

Benchmarking superannuation funds based on relative performance

In this article, we assess fund performance using data envelopment analysis (DEA). For each inefficient fund, DEA provides a set of role model funds whose best practices may be emulated for performance improvement. We find that the role models of most inefficient funds consist entirely of funds different from their own type. To overcome this situation, we suggest a multi-step DEA procedure. The procedure starts by categorizing funds on a hierarchical basis. We establish the hierarchy based on the frequency of efficient funds that belong to each fund type. Thereafter, a set of role model funds for each inefficient fund is found by pooling the funds in its own category and the funds that belongs to the categories at the lower levels in the hierarchy and applying DEA. This procedure is repeated by augmenting the pool with funds at the next higher level and so on until all the sampled funds are included. At each step, a set of role models is identified. An inefficient fund can thus reach the efficient frontier in stages. Statistical evidence suggests that membership and proportion of risky assets may have a negative association, and the fund size may have a positive association with fund performance.
