我国基金公司内部封闭式基金对开放式基金的补贴研究

由于封闭式基金与开放式基金的差异,基金公司倾向于补贴开放式基金而侵害封闭式基金的利益。经验证据表明,我国基金公司确实存在封闭式基金对开放式基金的补贴行为。论文进而构建了一个封闭式基金对开放式基金补贴模型,指出投资者偏好、市场预期的开放式基金销售量、激励机制、基金公司自身的管理能力是影响补贴行为的重要因素,并讨论了如何进行防范。     

Does corporate international diversification destroy value? Evidence from cross-border mergers and acquisitions

This paper investigates the valuation effects of corporate international diversification by examining cross-border mergers and acquisitions of US acquirers over the period 1990–2000. We find that, on average, acquisitions of “fairly valued” foreign business units do not lead to value discounts. In contrast, unrelated cross-border acquisitions result in a significant diversification discount of about 24% after accounting for the valuation of foreign targets. Furthermore, significant wealth gains accrue to foreign target shareholders regardless of the type of acquisition. Overall, our results suggest that international diversification does not destroy value while industrial diversification leads to discounts even after controlling for the pre-acquisition value of the target.     

Diversification,corporate governance and firm value in small markets: evidence from New Zealand

We find that diversified firms in New Zealand are associated with a value discount of 19–42 per cent relative to single‐segment (undiversified) firms. Although several competing explanations have been offered in the literature, we find that the strength of corporate governance explains between 15–21 per cent of this discount. Specifically, board size, busyness of directors, CEO ownership and whether or not compensation of directors includes equity‐based components collectively explain a large part of the reported discount. Our results from companies trading in New Zealand complement recent findings in the US by not only confirming the existence of a diversification discount but also emphasizing the role of poor governance in destroying shareholder wealth by pursuing a value‐destroying corporate strategy. All our results hold after controlling for potential endogeneity in the decision to diversify and the choice of corporate governance structure by employing two‐way fixed‐effects and dynamic‐panel generalized method of moments regression techniques.     

Do financial conglomerates create or destroy value? Evidence for the EU

There is an ongoing debate about whether firm focus creates or destroys shareholder value. Earlier literature has shown significant diversification discounts: firms that engage in multiple activities are valued lower. Various factors are important in determining the size of the discount, for example cross-subsidization and agency problems. The existing literature, however, generally focuses on non-financial firms or on banks combining investment and commercial banking. Our paper focuses specifically on the valuation of bank-insurance conglomerates. We find no universal diversification discount but significant variability. The discount is explained by the size (increasing), the familiarity with the conglomerate business model (decreasing) and the risk profile (decreasing). Our results are robust to the historical origin, the merger record and the age of the conglomerate, as well as peer group specification and outlier elimination.     

封闭式基金折价与管理绩效的实证研究

本文基于管理绩效理论,对我国封闭式基金折价现象进行实证研究。管理绩效理论认为,封闭式基金折价反映了投资者对于基金未来过低的管理能力的理性预期,未来管理绩效越差,折价越大。本文使用了多种基金绩效度量模型,分别采用引入时间哑变量和除去时间均值混合OLS回归方法以及Fama-Macbeth横截面回归方法,验证了折价率和未来管理绩效之间的关系。结果显示,封闭式基金折价和溢价反映了市场对于基金未来管理绩效的预期;当期折价率和未来管理绩效之间存在显著的正向关系,尤其在未来一个季度的时间内;这种关系不受非同步性交易效应和基金异质性的影响。本文同时发现,折价率对于未来管理绩效的解释能力强于过去的管理绩效对于未来管理绩效的解释能力。     

赎回权的价值与封闭式基金折价率研究——兼论“封转开”方案设计

本文比较了封闭式基金与对等的开放式基金之间的差异，认为缺少赎回权是封闭式基金产生折价的主要原因。在一个具有完全择时能力的封闭式基金投资者的假设条件下，本文推导并证实了赎回权价值上限和隐含折价率下限计算公式。基于赎回权，本文提出了“封转开”方案设计的一个新思路，希望对市场上正在热烈讨论的“封转开”问题有所启示。     

Taiwanese Mutual Fund Performance Under Different Central Bank of China Monetary Policy Environments

This study examines the performance of mutual funds under different Central Bank of China monetary policy environments in the emerging Taiwan market. To measure monetary policy changes effectively, we exploit changes in the discount rate and further categorize the monetary environment as either restrictive or expansive. We consider a restrictive monetary environment to be a period in which the discount rate rises, whereas an expansive monetary condition is a period in which the discount rate drops. It is found that all mutual funds, both domestic and international funds, exhibit a higher mean return, lower risk, and higher Sharpe and Treynor ratios under expansive monetary policy environments. Regression results show that domestic mutual fund returns are related significantly to local monetary policy. Furthermore, after controlling for the possible effect of macro factors on the association between the monetary policy dummy variable and mutual fund returns, the significant influence of monetary policy on domestic mutual fund returns remains robust. In contrast, changes in U.S. monetary policy stringency, in general, do not affect the performance of either domestic or international mutual funds in Taiwan.

全国社会保障基金发展的问题与展望

从2001年建立初至今,尽管全国社会保障基金规模稳步增长、投资收益水平逐步提高、管理体制和治理结构不断完善,但也还存在着规模较低、投资限定过严、资金来源缺乏稳定性等一些问题,并且未来发展方向也不尽明确。上述问题的解决对于全国社会保障基金的进一步发展具有重要的作用和意义。     

Past Returns and Investment Trust Discounts

Abstract:   The relationship between past net asset value returns and the current discount on investment trusts is investigated. The relationship is weaker for the component that is common to all trusts in the same sector, and is significantly stronger for more liquid trusts. The time lag before returns have their full impact on discounts is consistent with the requirements of distinguishing 'skill' from noise. Although discounts vary widely even within the same sector, the range of variation appears to be consistent with an arbitrage equilibrium, in which the profits of exploiting apparent pricing anomalies are just insufficient to invite arbitrage trades.     

我国证券投资基金的积极资产组合管理能力研究

本文以19支开放式基金和23支封闭式基金为研究样本,通过改进PCM模型,设计适用于非有效市场或弱有效市场的指标S,来考察我国证券投资基金在2005年1月1日至2007年6月30日这段研究区间内的积极资产组合管理能力,并对开放式基金和封闭式基金的积极资产组合管理能力进行比较分析。研究发现,开放式基金和封闭式基金均有较强的积极资产组合管理能力;封闭式基金的积极资产组合管理能力整体要高于开放式基金,特别是在上涨和震荡行情中;同时,市场走势的波动也会对基金的积极资产组合管理能力产生一定的影响。     

封闭式基金之谜的噪音理论解释

运用中国封闭式基金数据实证分析得出,资产代理人的缺失是现时噪音理论的缺陷,作为初期风险资产供给者的资产代理人,其行为特征会影响风险资产初期的价格函数;把噪音分为行业噪音与营销噪音可以解释封闭式基金上市溢价现象;资产代理人有多种的利益动机启动营销噪音,从而导致风险资产的初期溢价。     

Maximizing an equity portfolio excess growth rate: a new form of smart beta strategy?

It has been claimed that, for dynamic investment strategies, the simple act of rebalancing a portfolio can be a source of additional performance, sometimes referred to as the volatility pumping effect or the diversification bonus because volatility and diversification turn out to be key drivers of the portfolio performance. Stochastic portfolio theory suggests that the portfolio excess growth rate, defined as the difference between the portfolio expected growth rate and the weighted-average expected growth rate of the assets in the portfolio, is an important component of this additional performance (see Fernholz [Stochastic Portfolio Theory, 2002 (Springer)]). In this context, one might wonder whether maximizing a portfolio excess growth rate would lead to an improvement in the portfolio performance or risk-adjusted performance. This paper provides a thorough empirical analysis of the maximization of an equity portfolio excess growth rate in a portfolio construction context for individual stocks. In out-of-sample empirical tests conducted on individual stocks from 4 different regions (US, UK, Eurozone and Japan), we find that portfolios that maximize the excess growth rate are characterized by a strong negative exposure to the low volatility factor and a higher than 1 exposure to the market factor, implying that such portfolios are attractive alternatives to competing smart portfolios in markets where the low volatility anomaly does not hold (e.g. in the UK, or in rising interest rate scenarios) or in bull market environments.     

情绪投资组合模型及其实证分析--基于前景理论

投资者情绪对其决策有直接的影响,投资者的风险厌恶系数与其已有的投资业绩有关。本文在假设投资者风险厌恶且其风险厌恶系数受其损益情绪影响的条件下,以投资者损益情绪效用最大化为决策目标,建立基于投资者损益情绪的投资组合模型,有效地刻画出投资者的损益情绪对投资组合决策的影响。采用上证市场的行业指数进行实证分析,并与Markowitz模型进行对比,结果表明,情绪投资组合模型的组合效果更好。
