基金业绩归因与投资者行为

本文以2006年1月至2016年12月中国64家股票型主动管理基金为样本,从基金净资金流变化的角度,检验了投资者决策与基金业绩结构的关系,以期更好地理解投资者行为。本文结论有:(1)整体上,投资者在衡量基金经理能力时,更关注原始超额收益率或只基于市场风险调整风险敞口,这可能与中国市场投资工具仍然不够充分、风险难以有效对冲有关;(2)机构投资者相比个人投资者对风险敞口的识别更严格;(3)简单模型的优势集中在市场波动低、投资者情绪高的时期;(4)除基金经理能力外,净资金流变化对市场风险报酬也很敏感;(5)从alpha的角度,我国基金市场仍存在“赎回异象”,可能与“处置效应”有关,仍需提升投资者对风险的认知,引导市场形成更加科学的投资观念。     

海外投资者保护基金制度及借鉴

保护投资者尤其是保护中小投资者,是证券市场监管的核心内容,也是证券市场健康运行的基础.国际上,证券投资者保护机制已经有30多年的运行经验,很多方面值得我们借鉴.本文从法律框架、组织模式、资金来源、赔偿机制、运作情况等方面,对国际上主要国家和地区的证券投资者保护基金制度进行了比较,并结合我国证券市场特征,对我国证券投资者保护制度的建立和完善提出若干建议.     

基金组合披露、投资者关注与业绩持续性

本文以2006年至2014年间开放式股票型基金为样本,从投资者关注角度,研究分析了基金投资组合披露对其业绩持续性的影响。结果表明,超短期内投资者具有明显的反应不足,未能对组合披露足够关注。短期内组合披露会引发一定的市场关注,投资者模仿绩优基金投资组合并摒弃绩劣基金投资组合,投资者关注度会强化基金业绩持续性,且强化效应具有不对称性,投资者关注对绩优基金业绩持续性的影响更明显。此外,绩优基金可以将基金投资组合披露作为一种重要策略。     

阳光私募基金的投资者保护研究

私募证券基金在国外已经是一种有着成熟运作机制的投资工具,但国内的阳光私募基金还处在初级阶段.缺乏引导的阳光私募基金将不利于我国资本市场的发展,更不利于保护广大投资者的利益.因此本文从保护私募基金投资者利益角度出发,借鉴国外已有的相关制度,对我国阳光私募基金制度设计提出了初步设想.     

投资者情绪对基金业绩的影响研究——基于基金资金净流入视角

本文探索了投资者情绪对基金业绩的影响及其影响机制,通过构建中介效应模型分析投资者情绪对基金业绩的作用路径。研究结果表明我国开放式基金存在“智钱效应”,基金资金净流入较大的基金业绩表现要比资金净流入小的业绩好;投资者情绪对基金业绩有显著正相关关系,且当投资者情绪积极时会显著提高资金流入基金,从而使得基金业绩得到提升。通过进一步分析发现疫情等重大事件会增强投资者情绪对基金业绩的影响,提高基金业绩对投资者情绪的敏感度。

基金业绩、投资者有限注意力与基金申购

投资者注意力作为一种稀缺的认知资源对资产定价、投资决策等有重要影响。本文使用百度指数的用户关注度作为注意力的代理变量,考察了投资者有限注意力对基金投资决策的影响．分析了基金市场中影响投资者注意力的因素。当投资者购买基金时,由于面对可供选择的庞大数量基金．投资者的有限注意力将影响基金申购,而且有证据表明投资者注意到基金以后经过两到五周的时间才会中购基金;当投资者卖出基金时,由于仅面对少数几只己经买入的基金,投资者注意力不会影响基金赎回。此外,本文发现短期业绩较好和短期波动较大的基金更能吸引投资者的注意。同时基金的营销手段对于吸引投资者的注意力起到了良好的作用。

Investor Response to Mutual Fund Policy Variables

The effects of investment performance and macro-economic influences on money flow to individual mutual funds previously have been investigated and found to provide little explanatory power. In this article we investigate an additional category of factors that may logically be thought to affect the flow of money to funds, namely, the fund policy factors over which managers have some degree of control. These are: load/no-load status, sales commission structures, minimum dollar investment levels, and expenses. We establish associations between these factors and new money flows. Several significant relationships are found. Overall, however, the policy variables we investigated explain little of the variability in new money flows. A competitive equilibrium appears to exist such that no single fund attracts new money at disproportionately high rates through its policies. Our results, like those obtained for performance and macro-economic variables, highlight the inability of mutual fund research to date to explain adequately the flow of new money to individual funds.     

On Mutual Fund Investment Styles

Most mutual funds adopt investment styles that cluster arounda broad market benchmark. Few funds take extreme positions awayfrom the index, but those who do are more likely to favor growthstocks and past winners. The bias toward glamour and the tendencyof poorly performing value funds to shift styles may reflectagency and behavioral considerations. After adjusting for style,there is evidence that growth managers on average outperformvalue managers. Though a fund's factor loadings and its portfoliocharacteristics generally yield similar conclusions about itsstyle, an approach using portfolio characteristics predictsfund returns better.     

European Mutual Fund Performance

This paper presents an overview of the European mutual fund industry and investigates mutual fund performance using a survivorship bias controlled sample of 506 funds from the five most important mutual fund countries. The latter is done using the Carhart (1997) 4-factor asset-pricing model. In addition we investigate whether European fund managers exhibit 'hot hands', persistence in performance. Finally the influence of fund characteristics on risk-adjusted performance is considered. Our overall results suggest that European mutual funds, and especially small cap funds are able to add value, as indicated by their positive after cost alphas. If we add back management fees, four out of five countries exhibit significant out-performance at an aggregate level. Finally, we detect strong persistence in mean returns for funds investing in the UK. Our results deviate from most US studies that argue mutual funds under-perform the market by the amount of expenses they charge.     

Evaluating Mutual Fund Performance

We study standard mutual fund performance measures, using simulated funds whose characteristics mimic actual funds. We find that performance measures used in previous mutual fund research have little ability to detect economically large magnitudes (e.g., three percent per year) of abnormal fund performance, particularly if a fund's style characteristics differ from those of the value-weighted market portfolio. Power can be substantially improved, however, using event-study procedures that analyze a fund's stock trades. These procedures are feasible using time-series data sets on mutual fund portfolio holdings.

Mutual Fund Family Size and Mutual Fund Performance: The Role of Regulatory Changes

We examine whether the previously documented positive association between fund family size and fund performance is affected by significant regulatory changes (i.e., Regulation Fair Disclosure (Reg FD), the Global Settlement (GS), and increased scrutiny as a result of trading scandals) that have occurred in the last decade. Using Reg FD as a beginning point for these structural changes, we find that, while fund family size was positively associated with fund performance in the period prior to the regulatory changes, this advantage is significantly weaker in the period subsequent to the regulatory changes. Consistent with the weakened advantage of fund family size in fund performance, we find that the greater stock‐picking skill of larger fund families, measured using the earnings announcement returns of the stocks they trade, also weakened subsequent to the regulatory changes. Using narrower event windows around the regulatory changes, we find that the previously documented superior return of large fund families was partly attributable to selective disclosure. We also find that fund families implicated in the trading scandals experienced a decline in their performance during the scandal period. Finally, we examine the role of large investment banks in providing an advantage to large fund families. Family size was positively associated with the extent to which funds traded in the same direction as forecast revisions by analysts from large investment banks in the period prior to Reg FD and the GS and this association declined significantly after the two regulatory events.

The Persistence of Mutual Fund Performance

This paper analyzes how mutual fund performance relates to past performance. These tests are based on a multiple portfolio benchmark that was formed on the basis of securities characteristics. We find evidence that differences in performance between funds persist over time and that this persistence is consistent with the ability of fund managers to earn abnormal returns.
