我国证券投资基金预测能力的决定因素研究

基金预测能力是评价基金业绩的重要指标。本文利用扩展的T-M模型与H-M模型实证检验了基金的预测能力,发现有近45%的基金具有显著的选股能力,另近25%的基金具有显著的负择时能力。在基金预测能力检验的基础上,本文从基金特征、基金经理特征及基金家族特征入手探讨了影响基金预测能力的因素。通过Logit模型回归发现,基金公司规模、基金经理薪酬占总费用的比例及"自下而上"的资产配置理念对基金的选股能力具有显著的正面影响,而基金自身规模对选股能力具有负面效果。从择时能力上看,基金年限与基金经理薪酬占总费用的比例对基金的负择时具有显著"贡献",而基金公司规模对基金的负择时具有显著抑制作用。此外,没有发现基金经理特征影响基金预测能力的证据。

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.     

Portfolio concentration and fund manager performance

This research examines the relationships among portfolio concentration, fund manager skills, and fund performance in Taiwan's equity mutual fund industry, yielding several empirical findings as follows. First, after controlling for other factors, concentrated equity funds tend to have smaller net asset values, larger fund flows, higher turnover rates, and a younger age and prevail in smaller fund families. Second, concentrated fund managers buy and sell stocks more smartly based on economic trends or market factors than do diversified fund managers, i.e., they have better market‐timing abilities. Third, only partial evidence supports the premise that concentrated equity funds have better next‐quarter risk‐adjusted performances than do diversified ones, as these fund managers' skills positively correlate to risk‐adjusted fund performance. Fourth, fund managers who have better stock‐picking abilities and intensively invest in certain industries generally exhibit better Carhart's alpha in the next quarter than do other fund managers. Fifth, fund managers' stock‐picking abilities more closely relate to long‐term performance than do their market‐timing abilities. Lastly, positive performance persistence is much stronger than negative performance persistence, but concentrated funds do not have stronger performance persistence than do diversified funds.     

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.     

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.     

Do hedge funds dynamically manage systematic risk?

Defining systematic risk management (SRM) skill as persistently low fund systematic risk, we find evidence of time varying allocation of hedge fund management effort across the business cycle. In weak market states, skilled managers focus on minimization of systematic risk via dynamic reallocations across asset classes at the cost of fund alpha and foregoing market timing opportunities. As markets strengthen, attention shifts to asset selection within consistent asset classes. The superior performance of low systematic risk funds previously documented arises due to the superior asset selection ability of managers in strong market states. Incremental allocations by investors arise due to this superior performance and not due to recognition of SRM skill.     

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.     

Mutual fund liquidity timing ability in the higher moment framework

Using mutual fund data in Thailand, this study shows that fund managers can time the market-wide liquidity in the higher moment framework. High-performing fund managers demonstrate significantly positive liquidity timing ability, while low-performing fund managers do not. Thus, high-performing fund managers increase (decrease) the funds' exposure to the market during a high (low) market liquidity period, while low-performing fund managers do not show the liquidity timing ability. Moreover, only top-performing bank-related mutual funds possess the liquidity timing ability, supporting the information advantage hypothesis. Nonbank-related funds do not possess the liquidity timing ability at both the aggregate and portfolio levels. Several robustness tests confirm the findings.     

Emerging Market Exposures and the Predictability of Hedge Fund Returns

We examine emerging market and global macro hedge funds and find a significant positive relation between hedge funds’ future returns and their exposure to both emerging market equities and emerging market currencies. We present evidence that the strong predictive power of emerging market betas is related to the superior market‐timing ability of these fund managers. Results are robust after controlling for commonly used hedge fund factors, the emerging market equity index, lagged fund returns, liquidity risk, and fund characteristics. Our results suggest that hedge funds can earn positive excess returns by timing their exposure to emerging market securities.     

Coskewness timing ability in the mutual fund industry

The ability of mutual fund managers to time coskewness successfully can help them manage their portfolio’s exposure to potential losses and improve their fund’s performance. This study assesses whether mutual fund managers are able to manage the market exposure of their investment portfolios given a change in coskewness. We demonstrate that fund managers investing in Small Blend and Small Growth stocks possess the ability to time coskewness. On average, the fund managers of these two investment objectives increase the market exposures of their portfolios about 2.749 % and 1.340 %, respectively, based on their anticipations on future coskewness. Superiority is driven from the fact that the fund managers in small capitalization stocks are successfully able to manage the tail risk of their funds’ portfolios. The fund-by-fund results confirm that the number of individual funds succeeding in timing market skewness of the Small Blend and Small Growth investment objectives is larger than the remaining types. The main findings are robust when controlling for other types of timing ability, the periods of financial turbulence, and the construction of coskewness.
