Who benefits in a crisis? Evidence from hedge fund stock and option holdings

We use a unique data set of hedge fund long equity and equity option positions to investigate a significant lockup-related premium earned during the tech bubble (1999–2001) and financial crisis (2007–2009). Net fund flows are significantly greater among lockup funds during crisis and noncrisis periods. Managers of hedge funds with locked-up capital trade opportunistically against flow-motivated trades of non-lockup managers, consistent with a hypothesis of rent extraction in providing crisis era liquidity. The success of this opportunistic trading is concentrated during periods of high borrowing costs, in less liquid stock markets, and is enhanced by hedging in the equity option market.     

Interaction between securitization gains and abnormal loan loss provisions: Credit risk retention and fair value accounting

This study investigates whether managers use asset securitization gains to substitute loan loss provision (LLP) management for earnings management, and, if so, whether the percentage of credit risk retained affects such a relationship. The literature provides evidence that managers have used securitization transactions to boost earnings. Using 2001?2014 data for a sample of bank holding companies, I find that managers use securitization gains and LLPs as partial substitutes and that earnings management from securitization gains grows at an increasing rate to substitute income increasing LLP management as the level of risk retention increases. These findings are consistent with the argument that the higher the level of risk retention, the greater the potential impact on achieving earnings targets, given banks’ exercise of discretion over securitization gains through estimation of fair value of retained interest. In addition, I document that the substitution effect between the two tools is non‐existent in the post‐SFAS 166/167 period. Taken together, the findings have timely implications for accounting standards by informing the effect of risk retention that I measure through earnings management techniques. Moreover, my findings provide additional support for improved disclosures on assets‐backed securities.     

终身证券市场禁入的正当性难题及其化解

我国证券监管所采用的终身证券市场禁入，剥夺了行为人参与证券市场的资格或机会，需要接受“正当性”的拷问。基于公共利益理论、利益平衡分析等论证证券市场禁入的正当性，未深入到行为人自身内部寻找正当性根据，均存在一定的局限性。证券市场禁入的正当性基础，应当回归到行为人自身，注重行为人自身“适合”参与证券市场的可期待性。终身证券市场禁入具有鲜明的“惩罚性”，面临着责任追究无边界等正当性难题。化解这一难题的路径是去除证券市场禁入的“惩罚性”，允许被禁入对象“救赎”自己，建立终身证券市场禁入的适时退出程序，明确终身证券市场禁入的退出标准，动态跟踪监测被禁入对象个体情况，适时赋予其参与证券市场的“第二次机会”。     

How does reinsurance and derivatives usage affect financial performance? Evidence from the UK non-life insurance industry

A three-equation structural model is applied in this study to facilitate our examination of 1994–2011 regulatory returns data on UK non-life insurers, from which we find that those insurers using more reinsurance tended to have inferior financial performance, whilst those insurers with a predisposition towards risk management tended to have used both reinsurance and derivatives. We also find that those insurers with high loss ratios were found to have inferior financial performance. Our analysis sheds some light on the relationships between financial performance, reinsurance and derivative usage.     

VIX futures term structure and the expectations hypothesis

Tests of the expectations hypothesis reveal that the slope of the VIX futures term structure predicts the direction but not the magnitude of the evolution of the short-end of the curve, but predicts neither the direction nor the magnitude of short-term changes in the long-end of the curve. Relative value seeking spread trades, constructed to exploit such violations, deliver excess returns with annualized Sharpe ratios equal or greater than those of volatility-writing strategies deployed by VIX ETN's for a majority of the 32 spread trade combinations tested. I demonstrate that profits from beta-neutral variations of the spread trades, which are not compensation for taking on equity downside risk by design, are propagated by inflows of capital into VIX futures markets, after controlling for factors that measure changes in the availability of hedge fund capital, risk appetite, and momentum. At the heart of profits, and by extension the term structure anomalies, is a disproportionally elevated basis propagated by long VIX demand that enters the futures market through ETN channels.     

价值溢价与一月效应——来自上海A股市场的经验证据

以2000年1月至2011年12月沪市A股上市公司为样本,按Size-B/M方法构建6投资组合,考察我国股市的价值溢价是否存在一月效应现象,检验大盘股、小盘股价值溢价在1月和非1月是否不同,并采用CAPM模型检验价值溢价的一月效应。实证结果发现:1)采用账面市值比B/M划分成长-价值型股票组合,大盘股和小盘股股票都存在价值溢价;2)大盘股和小盘股的价值溢价在1月与非1月存在不同的模式——大盘股在1月存在显著的价值溢价,而小盘股的价值溢价主要在非1月的月份出现;3)CAPM模型能够解释我国股市从2007年1月至2011年12月期间的价值溢价。相对小盘股,大盘股的价值溢价的一月效应更为显著。     

我国资产证券化发展的现状与风险防范分析

证券化已成了世界现代经济生活中的普遍现象,对现代经济产生了巨大影响。我国从2005年12月起对银行业信贷资产进行证券化试点,正经受着"美国次贷危机"经验教训的洗礼。本文介绍了我国大陆在资产证券化领域近12年的摸索、讨论和试点情况,并在分析了资产证券化对我国金融体制建设的现实意义之后,提出了我国目前信贷资产证券化及资产支持证券风险防范的6个主要方面。     

QFⅡ与中美证券投资基金发展比较研究

加入WTO后,包括证券投资基金在内的我国金融服务业将逐步实施对外开放。2002年12月QFⅡ(合格的境外机构投资制度)制度正式实施,标志着外资将正式介入我国证券市场。我国的证券投资基金虽然经过连年的快速发展,但与美国等发达国家相比,规模仍然偏小,操作水平与投资理念也有较大差距。因此,作为新兴市场,我国的证券投资基金业在面临挑战的同时,也会有巨大的发展空间。     

我国证券市场的板块联动效应及模糊聚类分析

以上海证券市场的各分类样本指数为研究对象,首先分析了传统的五大类指数、A股、B股之间的相互及其与大盘的关联性,验证了B股市场运行的独立性。然后随机抽样了24个分类板块指数,研究了它们之间的相关性,并运用模糊聚类分析法对其进行了聚类分析。最后根据实证研究结果,对投资者提出有一定参考意义的投资操作建议。
