我国沪深300指数基金择时和选股能力实证分析

本文运用T-M模型和H-M模型，采用2012—2013年的交易数据，对我国已上市的21只沪深300指数基金的择时选股能力进行实证分析。实证结果显示：我国沪深300指数基金经理的选股能力较差，基金经理未能给投资者带来超额收益；在择时方面，基金经理普遍具有一定的择时能力，但不具备强择时能力；基金经理的择时能力和选股能力呈强烈的负相关性。     

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。

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.     

Performance evaluation of balanced pension plans

This paper examines the ability of balanced pension plan managers to successfully time the equity and bond market and select the appropriate assets within these markets. In order to evaluate both market timing abilities in these balanced pension plans, we extend the traditional equity market timing models to also account for bond market timing. As far as we know, we are among the first to apply this multifactor timing model to investigate equity and bond market timing simultaneously. This performance evaluation has been conducted on two samples of Spanish balanced pension plans, one with Euro Zone and one with World investment focus. This allows us to decompose managers’ skills into three components: selectivity, equity market timing, and bond market timing. Our findings suggest that the average stock-picking ability of pension plans is positive. World schemes tend to have positive bond timing skills, while Euro Zone pension plans are on average not able to time equity or bond markets.     

资产配置策略与基金系QDII收益分析

本文从前十大重仓股占比、股票集中度、行业集中度、投资区域集中度、夏普指数等指标研究基金系QDII资产配置策略与其收益的关系。统计数据结果表明,过于集中的资产配置对QDII基金收益产生了负效应。同时,QDII基金在成立时机选择、资产配置和外汇投资战略上都欠妥当。由此可见,对于QDII产品而言,资产组合的构建需要符合分散国内系统性风险的原则,否则不会使QDII这种外汇投资基金具有特殊的优势。     

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.     

A global approach to mutual funds market timing ability

In this paper, we globally investigate market timing abilities of mutual fund managers from the three perspectives: market return, market-wide volatility and aggregate liquidity. We propose a new specification to study market timing. Instead of considering an average market exposure for mutual funds, we allow mutual fund market betas to follow a random walk in the absence of market timing ability. As a consequence, we capture market exposure dynamics which is really due to manager market timing skills while allowing dynamics to come from other sources than market timing. We find that on average 6% of mutual funds display return market timing abilities while this percentage amounts to respectively 13% and 14% for volatility and liquidity market timing. We also analyze market timing by investment strategies and for surviving and dead funds. Dead funds exhibit lower volatility and liquidity timing skills than live funds.     

What Style Liquidity Timing Skills Do Mutual Fund Managers Possess?

Recent studies claim that mutual fund managers demonstrate strong MARKET liquidity timing skills. We extend their liquidity timing tests to the four‐factor case and investigate liquidity timing skills with respect to the MARKET, SIZE, VALUE and MOMENTUM factors. Contrary to these claims, we find no evidence that fund managers adjust market exposure in anticipation of market liquidity changes. We find rather strong evidence that fund managers successfully overweight small stocks as market liquidity increases. Our study also demonstrates that it is easy to misidentify SIZE liquidity timing as MARKET liquidity timing in models that focus only on MARKET liquidity timing.     

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.     

Stability, Asymmetry and Seasonality of Fund Performance: An Analysis of Australian Multi‐sector Managed Funds

Using a sample of Australian Multi-sector trusts we examine selectivity and market timing performance and extend the analysis to include the relatively new measure of volatility timing. This is of particular relevance to our data set, as high levels of volatility persistence are prevalent in Australia. In addition we consider the stability, asymmetry and seasonality of the various performance and risk measures. A survivorship adjustment procedure is also employed in order to assess the impact of survivorship on selectivity, market timing and volatility timing performance.     

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.
