研究人员布伦纳等人(2009)研究了公众公告在美国财政部的影响，类似于Balduzzi et al .(2001)。重点是企业债券市场，并指出资产回报的共同变动形式。第一个版本和影响已经在这个研究中被注意到。此外，这项研究还利用了意外的公告，并使用了计划外的公告(Charles和Darne,2014)。由于采用了一种简洁的多变量模式，研究人员能够评估价格的形成通常是基于经典定义的，然而，对于意外的新闻公告(Zolotoy et al .，2017)，有一些二分类的理解。股票的波动性显示了对新闻公告的不对称反应(Tanha et al .，2014)。公司债券在出人意料的新闻发布会上表现出一种不对称的一致性。好消息、坏消息和其他形式的新闻效应必须在这一背景下进行区分，在这种情况下也可以观察到不对称城市。例如，Boyd et al .(2005)认为，在很短的时间内，市场上发布的失业消息可能会产生严重的负面影响。然而，在某些情况下，如股票市场，也可能产生积极影响。美国国债在波动性上不会有多大的变化，在这种情况下，也可以观察到变化。在不确定因素的背景下，好消息和坏消息进一步加剧了它们对波动性的影响，这是基于新闻发布的时间。此外，有必要考虑市场工具的形式和其他形式的宏观经济约束已经出现在市场上。

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.
