Equity market neutral hedge funds and the stock market: an application of score-driven copula models

In this article, we study the time-varying market neutrality of equity market neutral hedge funds. We use data from the Hedge Fund Research? Equity Market Neutral Index (HFRX EH), which represents the performance of a portfolio of individual equity market neutral hedge funds. For each day, we measure different levels of association of the Standard and Poor’s 500 (S&;P 500) index and the HFRX EH. We use non-linear dynamic conditional score models of location, scale and copula that, to the best of our knowledge, have not yet been applied in the body of literature on hedge funds. We study whether the neutrality of the HFRX EH that is evidenced in the body of literature for the period of April 1993–April 2003 also holds for the following decade, for the period of May 2003–December 2016. We estimate different average levels of association for the pre-, during- and post-periods of the US financial crisis of 2008. We find that the association of the S&;P 500 and the HFRX EH, on average, is significantly positive for the pre- and post-periods of the financial crisis, and it is significantly negative for the period during the financial crisis.     

我国基金经理投资行为实证研究

我国证券市场快速发展,推动了基金业的迅猛增长,随着基金数量的增多,作为管理基金的基金经理的作用和地位正在迅速上升。基金经理的投资决策行为势必会影响到基金的业绩,如何综合评价基金经理的投资行为,是摆在我们面前的一大课题。本文在对国内外学者有关基金经理投资行为文献评析的基础上,提出了投资行为度的概念,并运用多元回归计量方法和突变评价法对我国基金经理的投资风格、投资策略、投资绩效、择股时机选择能力、风险管理能力以及个人行为模式和基金业绩之间的关系等进行了实证检验,得出了一些有意义的结论。最后从行为金融理论角度分析了中国证券投资基金经理行为偏离的根本原因,并提出相应的政策建议。

Exchange traded funds: leverage and liquidity

This paper examines the differences between leveraged and unleveraged Exchange Traded Funds (ETFs), particularly for liquidity and volatility characteristics. The impact of leverage on intraday liquidity (spread and depth) is analysed in two periods – one of normal volatility and the other of abnormal/high volatility. There is a significant difference in spread and depth of leveraged and unleveraged ETFs in periods of both normal volatility and high volatility; however, this difference is more pronounced in higher volatility periods. In high volatility periods, liquidity typically diminishes in all ETFs, and this is even more so for the leveraged ETFs. When leveraged ETFs are segregated into multiples based on their power to replicate the underlying benchmark (i.e. multiples of ?3, ?2, ?1, 2, 3), the difference in spreads between normal and high volatility periods is typically larger. The double-leveraged ETF has the most significant difference between the positive and negative counter parts. However, the relationship in the progression of the multiples does not change linearly to correspond with the level of volatility. This may be due to the nonlinear relation between volume and volatility. We shed light on the magnification effect of financial leverage on microstructure of the ETFs.     

Capacity Constraints and Hedge Fund Strategy Returns

Hedge funds have generated significant absolute returns (alpha) in the decade between 1995 and 2004. However, the level of alpha has declined substantially over this period. We investigate whether capacity constraints at the level of hedge fund strategies have been responsible for this decline. For four out of eight hedge fund strategies, capital inflows have statistically preceded negative movements in alpha, consistent with this hypothesis. We also find evidence that hedge fund fees have increased over the same period. Our results provide support for the Berk and Green (2004) rational model of active portfolio management.

主权财富基金投资法律环境新变化——评IMF“圣地亚哥原则”

主权财富基金在国际金融发展中的地位日益重要，由于其具有浓厚的政府控制特质，因而受到投资接受国的严格监管。为避免严格监管引发金融保护主义、阻碍跨国投资，由各方共同参与制定的国际规则将成为平衡彼此利益的有效手段，国际货币基金组织（IMF）组织制定的“圣地亚哥原则”是这一进程中最受瞩目的成果之一。对主权财富基金投资法律环境新变化的考察与研究无疑会对我国主权财富基金具有启发与借鉴意义。     

Closed-End Fund Expenses and Investment Selection

Investment returns on closed‐end funds are highly volatile. Because expenses have a definite negative impact on closed‐end fund returns, investors should include the expense ratio as a criterion for fund selection in addition to performance, investment objective, and risk of the fund. This paper constructs a model of the expense ratio of closed‐end funds to explain cross‐sectional differences in the expense ratios for the period between 1989–1996. We relate closed‐end fund expenses to fund characteristics and identify the factors that can help investors choose low expense closed‐end funds.
