Value at risk and the cross-section of hedge fund returns

Using two large hedge fund databases, this paper empirically tests the presence and significance of a cross-sectional relation between hedge fund returns and value at risk (VaR). The univariate and bivariate portfolio-level analyses as well as the fund-level regression results indicate a significantly positive relation between VaR and the cross-section of expected returns on live funds. During the period of January 1995 to December 2003, the live funds with high VaR outperform those with low VaR by an annual return difference of 9%. This risk-return tradeoff holds even after controlling for age, size, and liquidity factors. Furthermore, the risk profile of defunct funds is found to be different from that of live funds. The relation between downside risk and expected return is found to be negative for defunct funds because taking high risk by these funds can wipe out fund capital, and hence they become defunct. Meanwhile, voluntary closure makes some well performed funds with large assets and low risk fall into the defunct category. Hence, the risk-return relation for defunct funds is more complicated than what implies by survival. We demonstrate how to distinguish live funds from defunct funds on an ex ante basis. A trading rule based on buying the expected to live funds and selling the expected to disappear funds provides an annual profit of 8–10% depending on the investment horizons.

技术创新、金融市场泡沫与金融制度的适应性效率

金融市场对于技术创新的重要性是不言而喻的。但金融市场的发展不可避免地会产生泡沫。严重的泡沫会导致金融市场的崩溃,从而对经济增长造成灾难性的后果。政府对金融市场泡沫的不同干预方式又会将金融市场锁定在不同的发展路径。我们发现,政府的角色十分关键,金融市场的发展,一方面需要政府的良好执法来建立竞争性市场秩序,并降低既得利益集团对金融市场创新的阻挠;另一方面,又需要避免政府过多的行政干预所导致的对投资者权力的破坏。只有这样,才能有效地将泡沫效应转化为推动金融市场创新的原动力。     

How do great shocks influence the correlation between oil and international stock markets?

We investigate the impacts of great shocks (2003 Iraq War and 2008 Financial Crisis) on the correlations between oil and US/China stock markets, utilizing a novel MADCC (mixed asymmetry dynamic conditional correlation) model. This model successfully captures the coexistence of opposite signed asymmetries. We find that great shocks indeed increased the correlations. Further, results from the news impact surfaces indicate that correlations between oil and stock markets are higher to joint negative shocks; however, correlation between stock markets has stronger response to joint positive shocks.     

脱硫石膏制品体积稳定性试验研究

本试验对比了不同组分的石膏试件在升温、降温及干湿循环过程中的体积变形(以伸缩率计),分析了温度、湿度对石膏制品体积稳定性的影响.结果表明,脱硫石膏制品的伸缩率较小,在0.1‰～0.2‰之间,但随环境温度的改变体积变化较大,温度变形系数在1.5×10-5/℃以上.     

上市公司企业内部控制报告的完善

近年来,无论在资本市场发达的美国、欧洲,还是在市场刚刚起步的我国,都发生了一系列令人触目惊心的财务舞弊案件。有效的内部控制是防范上市公司财务舞弊的首道也可能是最后一道防线。内部控制报告已经成为内部控制是否有效的关注点,因而有必要对上市公司内部控制报告进一步展开研究。通过对内部控制报告的理论分析,本文建议我国上市公司应借鉴萨班斯法案构建较为完善的内部控制报告框架体系,并提出应通过完善注册会计师内部控制审核标准,进而提高内部控制的质量。
