英国论文代写-美国财政部公告对股票的影响。研究人员Brenner et al.(2009)研究了美国财政部公告的影响，类似于Balduzzi et al.(2001)的研究。重点关注公司债券市场，并注意到资产收益的联动形式。在这项研究中已经注意到了第一个版本及其影响。此外，本研究利用了意外通知，并在此过程中利用了未计划的通知。通过应用简约多元模型，研究人员能够评估价格形成通常基于经典定义，然而，对于令人惊讶的新闻公告存在一些二分法。股票波动对新闻公告的反应是不对称的。公司债券在出人意料的消息发布时表现出一种不对称的一致性。在这种背景下，好消息、坏消息和其他形式的新闻对量级的影响必须加以区分，在这种情况下也可以观察到不对称。论文范文英国论文代写-美国财政部公告对股票的影响分享给留学生阅读。
The second major set of differences was observed in the case of the scheduled and the unscheduled news releases. It was observed that scheduled news released had a more calming effect on the market as information was reduced in the market that led to resolutions in information uncertainty. Where uncertainty was reduced, then there was a decrease in volatility (Scharnagl and Stapf, 2015). In the case of unscheduled news releases on the other hand, information uncertainty was created. Hence, this resulted in increase in implied volatility. While the researchers Jinag et al. (2012) were able to identify that there was increase and decrease in volatility when there are announcements, they were not able to assess the magnitude of volatility spillovers. The magnitude changes do not come under their prediction, and this is one research limitation that could be addressed in this paper. Furthermore, the model work of Jiang et al. (2012) and Krieger et al. (2015) also used in this current work because how their model was able to predict spillover effects based on news broadcasts in the case of both extreme market events and other international markets.
Researchers Brenner et al. (2009) studied the effects of public announcements in the US treasury similar to the work of Balduzzi et al. (2001). The focus is on corporate bond market, and the form of co-movement of assets returns is noted. The first release and the impact have been noted in this research. Furthermore, this research makes use of surprise announcements and in doing so have made use of unscheduled announcements (Charles and Darné, 2014). With the application of a parsimonious multivariate mode, the researchers were able to assess that price formations are usually based on the classical definitions, however, there were some dichotomies understood with respect to surprise news announcements (Zolotoy et al., 2017). Volatility of stock shows an asymmetric reaction to the news announcements (Tanha et al., 2014). Corporate bonds exhibit a form of asymmetric alignment when it comes to surprise news announcements. Good news, bad news and other forms of news effect on magnitude must be differentiated in this context, asymmetricity could be observed in such cases, too. For instance, as Boyd et al. (2005) argued, in a very short period of time, unemployment news released in the market could result in majorly negative impact. Nevertheless, in some situations such as the equity market, there could be also a positive impact. Treasury bond would not show much change in volatility, and changes can be observed in such situations where there would be an ongoing expansion. Good news and bad news in the context of uncertainties are further exacerbated in their impact on volatility based on the time in which the news is released. Additionally, it is necessary to consider the form of market instrument that is used and other forms of macro-economic constraints that are present in the market already.
