MARKET VOLATILITY AND PERVERSE TIMING PERFORMANCE OF MUTUAL FUND MANAGERS

Prompted by the recent volatility in equity markets, I investigate performance evaluation methods and the mutual fund managers' ability to select undervalued investments and time major market movements during the high-market-volatility period of the 1980s. Specifically, I examine mutual fund managers' stock-selection and market-timing abilities by employing a five-factor risk-adjusted model based on Carhart's four-factor loading model and Bhattacharya and Pfleiderer's quadratic timing model adjusted for perverse timing behavior. Individually, some managers persistently affect fund performance through the selection of undervalued investments, however, at the expense of timing performance. In addition, funds that demonstrate an ability to time major market movements showed persistence in timing performance before and after the October market crash of 1987.     

Time‐Varying Fund Manager Skill

We propose a new definition of skill as general cognitive ability to pick stocks or time the market. We find evidence for stock picking in booms and market timing in recessions. Moreover, the same fund managers that pick stocks well in expansions also time the market well in recessions. These fund managers significantly outperform other funds and passive benchmarks. Our results suggest a new measure of managerial ability that weighs a fund's market timing more in recessions and stock picking more in booms. The measure displays more persistence than either market timing or stock picking alone and predicts fund performance.     

Security Concentration and Active Fund Management: Do Focused Funds Offer Superior Performance?

We examine gross fund returns based on the number of securities held and find no evidence that focused funds outperform diversified funds. After deducting expenses, focused funds significantly underperform. Controlling for various fund characteristics, fund performance is positively related to the fund's number of holdings both before and after expenses. We find evidence linking focused fund underperformance to agency and liquidity problems. Finally, the attrition rate of focused funds is higher than that of diversified funds. These results do not support the view that managers holding focused portfolios have superior stock‐picking skills or that focused funds provide value to investors.     

Recession managers and mutual fund performance

We find that fund managers who began their careers during recessions produce superior returns. This superior performance is not unconditional, as they exhibit better market timing than their non-recession counterparts in recessions, but do not demonstrate better stock picking in booms. Exploring managers' portfolio choices across years, we find that recession managers tilt their investments towards defensive, rather than cyclical, industries during and before recession periods. Overall, our findings support the argument that the economic conditions under which an individual initially entered the labour market exert a long-term impact on her career outcomes and decision-making.     

Timing and selectivity in Portuguese mutual fund performance

We extend the international evidence on timing and selectivity skills of fund managers by applying the Henriksson and Merton [Henriksson, R., Merton, R., 1981. On market timing and investment performance. II. Statistical procedures for evaluating forecasting skills. J. Bus. 54, 513–533] model to Portuguese based mutual funds investing in local, European and International equity.

The results show that managers do not exhibit selectivity and timing abilities, and there is even some evidence of negative timing. Furthermore, we observe a distance effect on stock selection performance, since fund managers that invest locally seem to perform better that those who invest in foreign markets. However, this effect is reverted with respect to market timing skills of fund managers, suggesting that International fund managers are more focused in market timing strategies.     

Time-varying fund manager skills of socially responsible investing (SRI) funds in developed and emerging markets

We examine stock selectivity and timing abilities in the market-wide return, volatility and liquidity of SRI fund managers. We find that multi-dimensional fund manager skills are time-varying and persistent in the short run, with developed market funds exhibiting longer persistence in all dimensions. Fund manager skills tend to be affected by fund characteristics (i.e., expense ratio, fund size, turnover and management tenure) and market characteristics (i.e., ESG market capitalization, mandatory ESG regulation and 10–2 yield spread). Fund managers of developed (emerging) market funds outperform (underperform) the market indices. For both fund types, fund managers possess exceptional volatility and liquidity timing despite poor return timing. Moreover, fund managers focus more (less) on timing the market’s return and less (more) on picking stocks when the prospect of recession keeps increasing (decreasing). Interestingly, if fund managers attempt to time the market-wide return or liquidity, stock selectivity will be worsened by their timing behavior.     

Do funds selected by managers’ skills perform better?

We construct a simple intuitive rating mechanism to evaluate stock picking and market timing skills of equity and hybrid equity fund managers in China. We find that both our skill-rated 5-star (SR-5S) fund and the Morningstar 5-star (MS-5S) fund portfolios outperform the market. The SR-5S fund portfolio outperforms its counterpart MS-5S portfolio in most situations, depending on whether portfolio performance is measured by the abnormal returns of the CAPM model, the Fama-French three-factor (FF3) model, the Carhart four-factor (CH4) model and the Fama-French five-factor (FF5) model. Both market timing skill and stock picking skill affect the performance difference between the SR-5S fund and MS-5S fund portfolios. Additionally, the departure of a SR-5S or MS-5S fund manager is associated with fund performance declines, and the declines in performance for SR-5S funds are generally larger than the declines for the MS-5S funds.

New Zealand mutual funds: measuring performance and persistence in performance

The present study investigates the performance of New Zealand mutual funds using a survivorship‐bias controlled sample of 143 funds for the period of 1990–2003. Our overall results suggest that New Zealand mutual funds have not been able to provide out‐performance. Alphas for equity funds, both domestic and international, are insignificantly different from zero, whereas balanced funds underperform significantly. There is no evidence of timing abilities by the fund managers. In the short term, significant evidence of return persistence for all funds is observed. This persistence, however, is driven by ‘icy hands’ rather than ‘hot hands’. Finally, we find the risk‐adjusted performance for equity funds to be positively related to fund size and expense ratio and negatively related to load charges.     

Pension fund manager skills over the economic cycle: the (non-)specialization cost

We study whether pension fund managers, as professionals of important social and financial products, are able to add value for their clients and adapt to economic changes. To this end, we analyze the performance and skills (market timing and stock picking) over the economic cycle from both pension fund and manager perspectives. This double analysis allows examining whether skills reside in managers and/or funds and control for manager substitutions. Despite the long-term nature of pension funds, we find that both fund and manager skills vary with market conditions, showing better evidence of stock-picking in booms, and of market timing in recessions. Nonetheless, top (bottom) funds and managers exhibit both (incorrect) skills in booms and in recessions. Some of the top (bottom) funds and managers are the best (worst) in both abilities in the same periods, but not in different periods, showing that not all managers have the ability to adapt to market conditions. Additionally, managers with limited skills tend to specialize because diversification requires multi-task skills and the non-specialization of these managers usually results in incorrect skills.     

Global equity fund performance, portfolio concentration, and the fundamental law of active management

This paper investigates the relation between portfolio concentration and the performance of global equity funds. Concentrated funds with higher levels of tracking error display better performance than their more broadly diversified counterparts. We show that the observed relation between portfolio concentration and performance is mostly driven by the breadth of the underlying fund strategies; not just by fund managers’ willingness to take big bets. Our results indicate that when investors strive to select the best-performing funds, they should not only consider fund managers’ tracking-error levels. More important is that they take into account the extent to which fund managers carefully allocate their risk budget across multiple investment strategies and have concentrated holdings in multiple market segments simultaneously.     

The Timing and Stock Selection Abilities of Bank Funds: Evidence Based on Meta-Analysis

This study investigates the risk-adjusted investment performance of the equity portfolios of bank trust departments, over the 1975–1992 period, attributable to their micro stock selection and macro market timing abilities. This paper first employs a widely known parametric statistical procedure developed by Henriksson and Merton to test jointly for the presence of either superior stock selection or market timing abilities. The paper then utilizes an alternative technique, called meta-analysis, to further examine the regression results obtained under the Henriksson–Merton model. The meta-analysis essentially eliminates such study artifacts as sampling and measurement errors through cumulation of results across studies. The findings of the joint test, based on the Henriksson–Merton model, do not support either superior stock selection abilities or market timing skills on the part of bank equity fund managers: selectivity measures are positive and timing measures are generally negative, but both measures are statistically insignificant. In contrast, the evidence based on the meta-analysis suggest that the managers of bank equity investment funds possess superior stock selection abilities and somewhat negative timing skills. Therefore, the results of this study suggest that, even though bank trust departments, like other categories of institutional investors, are unable to outperform a passive buy and hold investment strategy through timing the equity market, they are able to improve their investment performance through superior stock selection abilities.     

Information Diffusion among International Fund Managers: Multicountry Evidence

Investors seeking exposure to global equity markets commonly buy international mutual funds managed by locally based fund managers. How competitive is this form of intermediated investing? We investigate whether international equity fund managers mimic each other's portfolio holdings and analyze the performance implications of these actions. Managers based in the same country have more stocks held in common than those of their peers in other countries. Correlated trading among domestic fund managers contributes significantly to this pattern. Cross‐border managers' portfolio holdings and trades are also relevant to the actions of domestic managers. Stock selection strategies based on mimicry and differentiation both deliver short‐term superior performance. Mimicked sales occur while prices are rising.     

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.     

Performance attribution of mutual funds in India: outperformance or mis‐representation?

We conduct a novel holdings‐based performance attribution, particularly suited to emerging markets, for equity‐oriented active mutual funds in India. Although, we find significantly positive alphas for an average fund, the stated benchmarks are grossly mis‐specified. A style‐adjusted benchmark could beat the stated benchmarks by greater margins than the funds themselves. While funds’ trading activity consistently adds value, cash drag and market timing usually diminish value. Although, the best‐performing funds exhibit superior security selection abilities, their outperformance does not persist. However, despite the lack of persistence winner funds continue to generate significantly higher alphas than loser funds for quite some time.     

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 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.     

Is Concentration a Good Idea? Evidence from Active Fund Management

In this paper, we examine whether mutual fund managers in Taiwan produce superior performance through concentrated investment strategy, and find that mutual funds with higher degree of concentration have higher investment performance and lower risk during the period 2001–2009. Moreover, when the degree of industry concentration of fund holdings is higher, there is less impact on stock market performance. However, the premium of the market portfolio has more impact on the performance of funds when there is lower degree of industry concentration. We also find that the stock-picking and market-timing abilities of mutual fund managers result in funds with high degree of industry concentration having more returns and lower risks than the funds with low degree of industry concentration.     

Asset Allocation and Selectivity of Asian Mutual Funds During Financial Crisis

This paper evaluates the ability of US-based Asian mutual fund managers in coping with the 1997 Asian financial crisis. We find that the actively managed mutual funds under-perform with respect to the market portfolio by 1.71% in average monthly return. Such poor performance is caused by fund managers' relative weakness in country selection as well as in stock picking. Fund managers are also found to be more skillful in picking the correct market when the market is going up than going down. Our results are consistent with the literature that asset allocation in Asian mutual funds is a dominating factor relative to selectivity in explaining fund returns during the financial crisis. In addition, there exists a negative relation between asset allocation ability and selectivity of fund managers.     

A comparative performance of conventional and Islamic unit trusts: Market timing and persistence evidence

It is expected that the returns and resistance of Islamic mutual funds will be different from conventional mutual funds as the former have limited choices for portfolio diversification. This article analyses the performance of conventional and Islamic unit trusts for the period February 1995 to July 2012 in the Malaysian market, one of the most developed Islamic mutual fund markets. The performance analysis is based on four parameters: (i) risk-adjusted returns of unit trusts; (ii) market timing abilities; (iii) selection performance; and (iv) persistence. The results of this study suggest that the returns of both conventional and Islamic unit trusts have outperformed the market throughout the sample period. The results for market timing and selectivity are mostly the same for both categories of funds. However, Islamic unit trusts seem to have better resistance to market downturn than conventional unit trusts. The results of this research can be used by investors to identify funds or create portfolios that are more suitable for a recessionary scenario and for fund managers to better manage their portfolio performance during times when markets are likely to fall. The findings in this article are highly relevant for policymakers, investors and fund managers to determine policy matters, deciding on investment and marketing strategy for Islamic mutual funds.
