中国开放式基金选股和择时能力的实证分析

经过6年的发展,我国开放式基金发展迅速,截至2007年9月30日我国共有305只开放式基金,与此同时开放式基金对证券市场的影响也越来越大.开放式基金风险和收益、选股和择时能力等问题一直是国内外学者关心的一个话题.对开放式基金风险和收益、选股和择时能力的研究不仅关系到开放式基金本身的发展,也关系到投资者的切身利益.本文在收集2004年1月1日至2007年6月30日开放式基金3年半的数据基础上,应用国外成熟市场对开放式基金评价的指标,分析了中国开放式基金的选股能力和择时能力等问题,得出我国大部分开放式基金具有专家理财的特点,有一定选股能力但选时能力不是很强的结论.     

我国开放式基金绩效及选股和择时能力研究

近年来,开放式基金逐渐成为我国基金市场的绝对主体。开放式基金能否取得较好的绩效受到市场的普遍关注。本文选取了资金管理规模前20位的公司,并从中随机挑选1只基金,运用詹森指数、特雷诺比率、夏普指数和信息比率等单因素模型和Fama-French三因素模型对开放式基金的绩效进行分析,并使用T-M模型、H-M模型、C-L模型对基金经理人股票选股与择时能力进行分析。结果发现:第一,我国开放式基金经理的选股能力存在时变性,在上升期具备选股能力,在下跌期不具备选股能力,而无论是在上升期还是下跌期,基金经理普遍不具备择时能力。第二,在市场上升期基金经理比较注意对风险的把控,系统性风险较小,而在下跌期基金投资组合的系统性风险明显上升,基金经理冒险意愿上升,当市场出现大幅度下跌时,其不理性行为会加剧市场的波动。本文的研究结论有利于提升投资者的风险意识和理性意识、促进外部监管部门的精准监管审查,并能够激励基金经理人提高自身风险管控的能力。     

市场波动中的中国开放式基金是否存在选股择时能力——分时段下的比较研究

本文利用分时段比较研究中国三种主要开放式基金在股市涨落中是否存在选股择时能力,以帮助投资者对其形成初步的认识。研究发现,目前的两种主要评价模型更适合在市场相对平稳时期评价中国基金的选股择时能力。当市场剧烈波动时,模型解释力较弱;基金总体仅具有极为微弱的选股能力,择时能力欠佳,且不同类型基金在市场不同波动阶段选股择时能力差异较大;市场下降期往往同时具有一定的选股和择时能力,但其他时段两种能力则具有较强的负相关性。

中国公募基金挖掘了股票市场异象吗？

公募基金是我国重要的机构投资者之一,分析其投资逻辑对理解机构投资者行为和公募基金的选择至关重要。基于2005年至2019年主动管理偏股型开放式基金数据,本文检验了公募基金对A股市场87个异象因子的挖掘。为解决因子维度过大问题,本文采用非参方法从87个异象因子中提取有效信息的综合指标A-Score,并根据基金持仓构建基金的异象投资指标AIM(Anomalies Investing Measure)。结果显示:(1)中国公募基金挖掘了市场异象;(2)利用AIM可以选择表现更好的基金,并能获得0.45%的月度多空组合收益;(3)基金经理的选股能力、风格选择能力和风控能力是其挖掘异象收益的主要来源;(4)异象挖掘可以为基金带来长期资金流,同时也缓和了市场的错误定价。     

Life insurance companies as investment managers: New implications for consumers

This paper examines the attractiveness of the equity portfolios of life insurance companies as an alternative investment to mutual funds. In particular, this study analyzes the risk-adjusted investment performance of the stock portfolios of life insurance companies, attributable to their stock selection and market timing abilities. Using conventional measures of risk-adjusted portfolio performance, we find that life insurance companies exhibit performance similar to mutual funds. The evidence suggests that the life insurance companies, like their mutual fund counterparts, fail to exhibit differential stock selection or market timing abilities that are statistically significant. While the risk-adjusted investment performance of the two investment vehicles is similar, the variable annuity contracts of life insurance companies may offer an edge over mutual funds due to their ability to defer taxes.     

The Market Timing Ability of UK Mutual Funds

Abstract:  We apply a recent nonparametric methodology to test the market timing skills of UK equity and balanced mutual funds. The methodology has a number of advantages over the widely used regression based tests of Treynor-Mazuy (1966) and Henriksson-Merton (1981) . We find a relatively small number of funds (around 1%) demonstrate positive market timing ability at a 5% significance level while around 19% of funds exhibit negative timing and on average funds miss-time the market. However, controlling for publicly available information we find very little evidence of market timing ability based on private timing signals. In terms of investment styles, there are a small number of successful positive market timers amongst Equity Income and 'All Company' funds but not among either Small Stock funds or Balanced funds, although a few small stock funds are found to time a small stock index rather than a broad market index.     

The impact of the Arab Spring and the Ebola outbreak on African equity mutual fund investor decisions

Financial development and stock markets have been widely considered to be key factors in economic growth. Among institutional investors, mutual funds play a key role in providing financial resources to stock markets, particularly in developing countries. Different from other investments, mutual fund flows could be affected by retail investors’ behavior and their overreaction to specific events. We considered 78 equity mutual funds that are geographically specialized in African countries and observed monthly flows and performance for the period of 2006–2015. We find that two major events, Ebola and the Arab Spring, significantly affected the fund flows, controlling for fund performance, expenses and market returns. Retail investors over-reacted to these major events, withdrawing their savings from the African mutual funds. This result is particularly strong when connected to the media coverage of these events: the higher the number of articles about Arab Spring and Ebola, the higher the withdrawals. These irrational investors’ behavior damaged the funds’ managers market timing ability, and reduced the equity capital injection into African stock markets. Our results have several implications for both holders of frontier market mutual funds and the overall asset management industry.     

SELECTIVITY,MARKET TIMING,AND RANDOM BETA BEHAVIOR OF MUTUAL FUNDS: A GENERALIZED MODEL

This paper presents a generalized varying parameter model to investigate the performance of mutual funds. The model allows beta nonstationarity to include both market timing and random beta behavior; therefore, it can be regarded as a general case of previous research. Forty-three funds with a wide range of objectives are examined. The generalized varying parameter results indicate that about 30 percent of the funds show selectivity, 19 percent have random betas, and 14 percent indicate significant, yet negative, market timing performance. Therefore, mutual funds, as a group, show no market timing ability. The apparent ability to select undervalued securities, however, seems to conflict with the efficient markets hypothesis.

Dividend or growth funds: What drives individual investors' choices?

We study dividend fund buying behavior using over 80,000 individual Chinese mutual fund investors from a private Chinese mutual fund account dataset. Based on a variety of specifications and logistic regressions, we empirically investigate investors' characteristics in choosing dividend-paying and/or growth mutual funds under different market scenarios. To the best of our knowledge, this research represents an initial attempt to study individual dividend investors in mutual fund markets. We find that older Chinese investors prefer dividend-paying funds less than growth funds, but this depends on different market conditions, and the age effect shows a nonlinear mode when considering age grouping. Moreover, investors' prior experience plays a crucial role in choosing the fund type; however, the conclusions vary with market scenarios. In addition, female investors prefer more dividend-paying funds than do male investors, but investing experience counteracts this difference. We also find that geographic location is a contributor when investors decide the fund type.     

The dynamics between stock returns and mutual fund flows: empirical evidence from the Greek market

This paper examines the interaction between mutual fund flows and stock returns in Greece. Specifically, we investigate the possibility of a causality mechanism through which mutual funds flows may affect stock returns and vice versa. The statistical evidence derived from the error correction model indicates that there is a bidirectional causality between mutual fund flows and stock returns. Cointegration results show that mutual funds flows cause stock returns to rise or fall. This may be explained by the fact that, in Greece, equity mutual funds are obliged by law to invest a certain percentage of their cash in stocks. Thus, inflows and outflows of cash in equity funds seem to cause higher and lower stock returns in Greek stock market.     

Mutual Funds and Stock and Bond Market Stability

The unprecedented growth of mutual funds has raised questions about the impact of mutual fund flows on stock and bond prices. Many believe that the equity bull market of the 1990s is attributable to the huge flows of funds into equity mutual funds during this period and that a withdrawal of those funds could send stock prices plummeting. This article investigates the relationship between aggregate monthly mutual fund flows (sales, redemptions, and net sales) and stock and bond monthly returns during a 30-year period beginning January 1961 utilizing Granger causality and instrumental variables analysis. With one exception, flows into stock and bond funds have not affected either stock and bond returns. The exception is 1971–1981, when widespread redemptions from equity mutual funds significantly depressed stock returns. In contrast, the magnitude of flows into both stock and bond funds are affected significantly by stock and bond returns.
