This study investigates how the corporate bond's characteristics and Betas affect bond returns by using extensive Korean corporate bonds data from 2001 to the first half of 2007. Overall, our results indicate that bond characteristics provide significant explanations to excess returns while market factors (i.e., Betas) do not. It is strikingly different from the U.S. study of Gebhardt et al. (2005), which showed that market factors notably affect the excess returns of U.S. corporate bonds. 相似文献

This paper investigates the liquidity of two different electronic trading systems – the APT system at LIFFE and the DTB system. First we describe the different characteristics of the trading systems and give potential reasons as to why they might differ in liquidity. Second we investigate empirically the liquidity provided by the two trading system. The comparison is especially interesting because the Bund Futures instruments traded are identical and the markets are open simultaneously. The intra-day data used in the study is from August 1997 to February 1998. The results show that the APT has smaller spread but the DTB is slightly deeper. 相似文献

This study examines the occurrence of informed trading in public debt issued by companies in the United States. I find that earnings surprises are positively associated with bond price changes prior to the release of financial report data to the public, for firms with non‐investment‐grade ratings. Additionally, I find that the effect appears to be driven by firms with publicly traded equity. Evidence further indicates an increase in trading activity during the time window between report period end date and filing date, for firms with larger earnings surprises. 相似文献

We develop a general form logarithmic vector multiplicative error model (log-vMEM). The log-vMEM improves on existing models in two ways. First, it is a more general form model as it allows the error terms to be cross-dependent and relaxes weak exogeneity restrictions. Second, the log-vMEM specification guarantees that the conditional means are non-negative without any restrictions imposed on the parameters. We further propose a multivariate lognormal distribution and a joint maximum likelihood estimation strategy. The model is applied to high frequency data associated with a number of NYSE-listed stocks. The results reveal empirical support for full interdependence of trading duration, volume and volatility, with the log-vMEM providing a better fit to the data than a competing model. Moreover, we find that unexpected duration and volume dominate observed duration and volume in terms of information content, and that volatility and volatility shocks affect duration in different directions. These results are interpreted with reference to extant microstructure theory. 相似文献

Using a quasi-natural experiment, this study examines the effects of margin trading and short selling on bond yield spread in China. It finds that both margin trading and short selling can reduce bond yield spread. Additionally, it finds that margin trading lowers firms’ debt ratios and increases their credit ratings, which explains the reduced spread. In other words, margin trading can impact investors’ decisions by revealing positive information about a firm. Another finding is that short selling lowers the bond yield spread by decreasing earnings management, suggesting that short selling has an impact on investors’ decisions through its effect on corporate governance. Our results suggest that margin trading transmits positive information and short selling impacts firms’ policies. These results provide support for future regulations of margin trading and short selling. 相似文献

This paper empirically examines whether insider trading sanctions in the USA in the 1980s reduced insider trading in advance of mergers and acquisitions (M&A). Using a sample consisting of 291 firms, both merged and non‐merged in 1983 and 1989, I measured insider trading volume and the “news media effect.” I conclude that the sanctions reduced insider trading on average, and also resulted in larger noise trading on M&A‐related news and rumors. No evidence was found that insiders were increasingly camouflaging their trades by concentrating them on days on that they knew trading volume would be abnormally high, such as on days containing M&A‐related news. 相似文献

Using data on Canadian bond futures, we examine how high-frequency traders (HFTs) interact with institutions building large positions. In contrast to recent findings, we find HFTs in the data act as small-sized liquidity suppliers, and we reject the hypothesis that they engage in back running, a predatory trading strategy. Using a quasi-experiment in November 2011, in which a number of HFTs started trading the bond future, we run a difference-in-differences event study and find more competition among HFTs improves implementation shortfall, effective spreads, and short-term price impacts for institutional trading in Canadian bond futures. 相似文献

This paper is a continuous time version of Holden and Subrahmanyam (Economics Letters 44 (1994) 181). The paper extends Kyle (Econometrica 53 (1985) 1315) by introducing risk aversion on the side of the monopolist informed trader and allows for the liquidity traders instantaneous demand to depend on cost of trading, as well as on the risk of the stock. The main result of the paper is that, in equilibrium, the price pressure decreases with time regardless of the elasticity of the liquidity demand function. 相似文献

本章主要从数量的角度分析了银行间债券市场的主体交易行为。由于传统金融市场理论与银行间市场的实际情况存在不符的情况,作者试图用行为经济学理论来解释银行间市场的主体交易行为。由于数据方面的原因,本实证分析仅局限于银行间现券交易。实证结果显示,银行间市场不同主体之间的行为存在显著的差异性。最后,论文引入行为因子,对传统债券定价模型进行修正。 相似文献

本文基于政府债券规模和流动性的双重视角,构建动态随机一般均衡模型,通过理论分析和数值模拟,研究二者对实体经济发展和金融风险变量的影响。研究显示:政府债券规模的增加促进了投资,刺激了产出和劳动供给,但过度扩张对实体经济也带来"挤占投资"和物价上升、消费下降等负面效应,同时通过债券作为金融资产的特性向金融部门蔓延并形成金融风险集聚;政府债券流动性增强一定程度上刺激了投资,促进了物价稳定,但也存在"挤占消费"和引起经济波动等负面效应;而政府债券流动性的提升有利于缓释金融风险,对实体经济长期可持续发展有益,但流动性过高也会带来系统性金融风险集聚。本文从促进政府债券一级市场和二级市场协同发展、总量和结构合理匹配、政府债券与实体经济有机契合、政府债券流动性管理与金融供给侧密切衔接等方面提出政策建议。 相似文献

传统的久期模型实现风险免疫的前提条件是利率变动幅度非常小。当利率变化较大幅度时,久期匹配不足以实现良好免疫,此时凸性对价格变动有正的影响。此外,传统的久期和凸性分析都没有考虑违约风险的存在,这将导致免疫失败。现代金融机构的宏观套期保值必须在考虑违约风险的基础上将久期和凸性分析加以结合,以实现良好的免疫。 相似文献
