保本基金的投资组合保险策略运用及建议

保本基金的运作核心是投资组合保险策略，我国保本基金均采用简单参数的组合保险策略。在国内零息债券缺乏、股市波动大的情况下，如何设定最低保险额度、合理的风险放大倍数以及动态调整风险资产比例，成为保本基金运作的难题。本首先简要介绍了投资组合保险策略原理，在此基础上分析了国内保本基金的组合保险策略，然后结合运作原理提出改进建议。     

投资组合保险策略的运作原理

保本基金与组合保险策略 投资组合保险1理论起源于20世纪80年代的美国.由伯克利大学金融学教授Hayne E Leland和Mark Rubinstein创始的这项技术自1983年被首次应用于Wells Fargo Investment Advisors、AetnaLife、Casualty三家金融机构的投资管理运作实践中,并在80年代中期得到蓬勃发展.该理论对于较不愿承受风险的投资者或处于下跌的市况来说.是一种很好的投资策略.

两全其美选"保本"

证监会网站的信息显示,截至2011年1月25日,共计有11只保本基金等待在未来半年内完成审核。2011年上半年末我国保本型基金的数量和规模或可扩容一倍以上,被业内人士形容为爆发式的发展。纵观海外保本基金的历史,其获得快速发展都是在银行存款利率持续低位,股市前景不明朗,投资者投资意愿低迷的市场环境下,投资者亟须能规避市场风险、兼顾保值增值的投资产品出现之时。保本基金(Guaranteed Fund)产品通常设计为在固定的保本周期持有结束时(国内一般为3年,海外有长达7～12     

我国保本基金的保本策略研究

保本基金作为一种国际上流行的基金品种,在我国已取得了一定的发展,但由于国内金融市场的特殊性,保本基金保本策略的创新和应用仍然处于较初级的阶段。随着股指期货的推出,各种创新型保本策略在国内有了较大的发展空间。本文结合当前我国金融市场环境,将股指期货引入保本基金策略,并运用实证分析、Monte Carlo模拟的方法对各种策略的优势、局限性以及适用情况进行全面的评估与比较,为其实际应用提供有价值的理论参考。     

平均价格投资组合保险策略研究

根据连续时间条件下CPPI策略的操作原理,引入亚式期权,本文构造了一种基于平均价格的投资组合保险策略.通过采用上证综合指数,对APPI策略在多头、空头和震荡三个时期进行历史数据实证模拟,并与标准CPPI策略做对比.结果发现：多头时期APPI策略表现不如CPPI策略;空头和震荡时期,保险效果则优于标准CPPI策略.

Style and performance of international socially responsible funds in Europe

This paper analyses the performance and investment styles of internationally oriented Socially Responsible Investment (SRI) funds, domiciled in eight European markets, in comparison with characteristics-matched conventional funds. To the best of our knowledge, this is the first multi-country study, focused on international SRI funds (investing in Global and in European equities), to combine the matched-pairs approach with the use of robust conditional multi-factor performance evaluation models, which allow for both time-varying alphas and betas and also control for home biases and spurious regression biases.In general, the results show that differences in the performance of international SRI funds and their conventional peers are not statistically significant. Regarding investment styles, SRI and conventional funds exhibit similar factor exposures in most cases. In addition, conventional benchmarks present a higher explaining power of SRI fund returns than SRI benchmarks. Our results also show significant differences in the investment styles of SRI funds according to whether they use “best-in-class” screening strategies or not. When compared to SRI funds that employ simple negative and/or positive screens, SRI “best-in-class” funds present significantly lower exposures to small caps and momentum strategies and significantly higher exposures to local stocks.     

Risk Management: Coordinating Corporate Investment and Financing Policies

This paper develops a general framework for analyzing corporate risk management policies. We begin by observing that if external sources of finance are more costly to corporations than internally generated funds, there will typically be a benefit to hedging: hedging adds value to the extent that it helps ensure that a corporation has sufficient internal funds available to take advantage of attractive investment opportunities. We then argue that this simple observation has wide ranging implications for the design of risk management strategies. We delineate how these strategies should depend on such factors as shocks to investment and financing opportunities. We also discuss exchange rate hedging strategies for multinationals, as well as strategies involving “nonlinear” instruments like options.     

Mutual Fund Tax Clienteles

Mutual funds are held by investors in taxable and tax‐qualified retirement accounts. We investigate whether the characteristics, investment strategies, and performance of mutual funds held by these diverse tax clienteles differ. Examining both mutual fund distributions and mutual fund holdings, we find that funds held primarily by taxable investors choose investment strategies that result in lower tax burdens than funds held primarily in tax‐qualified accounts. Despite these differences, we find no evidence that any investment constraints that may arise from these tax‐efficient investment strategies result in performance differences between funds held by different tax clienteles.     

Institutional Traders' Behavior in an Emerging Stock Market: Empirical Evidence on Polish Pension Fund Investors

Abstract:   In this paper, we contribute to the literature on institutional herding and feedback trading by analysing the investment behavior of pension funds on the Polish stock market. Pension funds entered into the stock market due to the national pension system reform in 1999, providing a unique opportunity to receive deeper insight into the behavior of institutional investors in an emerging capital market. Our results show that Polish pension fund investors are to a greater extent involved in herd‐like behavior and pursue feedback trading strategies more often than their counterparts in mature markets. This finding is primarily attributed to a stringent investment regulation and high market concentration. We do not detect, however, that trading by the pension funds exerts significant influence on the future stock prices.

Investing in mutual funds when returns are predictable

This paper forms investment strategies in US domestic equity mutual funds, incorporating predictability in (i) manager skills, (ii) fund risk loadings, and (iii) benchmark returns. We find predictability in manager skills to be the dominant source of investment profitability—long-only strategies that incorporate such predictability outperform their Fama-French and momentum benchmarks by 2 to 4%/year by timing industries over the business cycle, and by an additional 3 to 6%/year by choosing funds that outperform their industry benchmarks. Our findings indicate that active management adds significant value, and that industries are important in locating outperforming mutual funds.     

What drives the performance of convertible-bond funds?

This paper examines the performance of US mutual funds that invest primarily in convertible bonds. Multivariate cross-sectional analyses show a significant relation between a fund’s performance and its asset composition: the higher the difference in the percentage of assets invested in convertible bonds compared to the percentage invested in stocks, the higher the performance, on average. We show that this result can be explained by factors associated with investment opportunities in the convertible-bond market and trading strategies related to convertible arbitrage, as typically performed by hedge funds. Overall, convertible-bond fund performance measured by alpha is comparable to a passive investment in stocks, bonds, and convertible bonds. This performance is the result of weak selection skills and successful timing strategies related to convertible arbitrage.     

Dynamic preferences for popular investment strategies in pension funds

In this paper, we characterize dynamic investment strategies that are consistent with the expected utility setting and more generally with the forward utility setting. Two popular dynamic strategies in the pension funds industry are used to illustrate our results: a constant proportion portfolio insurance (CPPI) strategy and a life-cycle strategy. For the CPPI strategy, we are able to infer preferences of the pension fund’s manager from her investment strategy, and to exhibit the specific expected utility maximization that makes this strategy optimal at any given time horizon. In the Black–Scholes market with deterministic parameters, we are able to show that traditional life-cycle funds are not optimal to any expected utility maximizers. We also prove that a CPPI strategy is optimal for a fund manager with HARA utility function, while an investor with a SAHARA utility function will choose a time-decreasing allocation to risky assets in the same spirit as the life-cycle funds strategy. Finally, we suggest how to modify these strategies if the financial market follows a more general diffusion process than in the Black–Scholes market.     

私有信息优势还是投研分析能力?——绩优基金与绩劣基金信息挖掘行为比较分析

基于开放型股票投资基金的重仓股数据,本文分析绩优基金与绩劣基金的信息挖掘行为有何异同,以判断基金绩效是否来自于其信息分析能力。研究发现,绩优基金交易行为的信息挖掘特征更为显著,而绩劣基金则未表现出信息挖掘行为。而且,实证分析发现,绩优基金更高的信息挖掘水平并非取决于信息获取优势,二者网络中心度并无显著差异。但是,择时择股等能力的显著差异意味着绩优基金相对较高的信息挖掘水平来源于其更优的投研能力。此外,绩优基金的信息挖掘行为随着市场环境变化而调整。     

证券投资基金投资组合与投资策略的匹配性研究

对证券投资基金行为选择的研究，一直是金融经济学关注的焦点问题之一。本文对我国证券投资基金投资组合的构建和调整与其投资策略的匹配性问题进行了研究，发现绝大部分证券投资基金存在实际投资所承担的风险远远偏离其投资策略所表明的风险偏好类型。同时，由于市场环境的变化，无论是风险偏好型还是风险中性的基金，在实际投资中大多转型成了风险规避型基金。
