理解波动性冲击传导影响的第二个主要原因是了解国际投资组合将如何受到影响。国际金融投资组合必须以适当的方式加以维护，这样的投资组合不会受到任何风险，因为投资者将在这样的不确定性中损失太多。他们必须为风险做准备。风险管理考虑的是股票市场的变化，而新闻公告无疑是一个重要的影响因素。在这种背景下，有必要研究波动性冲击是如何产生的，因为它会带来新闻冲击。机会是为风险分析师创造的。一旦风险分析师能够理解市场波动是如何传播的，他们就能理解系统的传播和影响因素(Cakan等人，2015年)。然后，根据计划中的新闻传输或意外新闻传输的工作方式，他们将能够向客户提供交易策略。当他们与股票分析师合作时，人们更喜欢有利可图的交易策略(Donders和Vorst，1996年;Ederington和李,1996)。蒋等人(2010)提出的第三个理由是，对波动性溢出效应和新闻发布的分析，将对形势的基本面和波动性的蔓延产生影响。波动的蔓延及其定义在研究工作中不同，但人们观察到这是一些共识。传染被理解为以一种未曾预料的方式传播的冲击。有时，由于一体化市场的相互影响，有时会出现“溢出效应”，有时也会相互依赖，因为一体化市场也会并行存在。在新闻效应的影响下，传染与正常的问题有区别，因为它不是正常的相互依存关系。因此，根据江等(2010)的说法，当研究在理解传播过程中进行研究时，识别并隔离传染效应是很容易的。研究溢出效应及其与宏观经济新闻公告的关系的最后一个原因是，它是如何影响市场效率的。

The second main reason for understanding impact of volatility shock transmission is to know how international portfolio will be affected. International financial portfolios have to be maintained in the proper manner and no risks to such portfolios would be entertained as investors would stand to lose much in such uncertainty. They have to prepare for risks. Risk management considers changes in stock market, and news announcements are undeniably an important influencing factor. In this context, it becomes necessary to study how volatility shocks are created because of the news impact. Opportunities are created for risk analysts. Once the risk analyst is able to understand how volatility is transmitted in the market, they can understand the systematic transmission and impact factors (Cakan et al., 2015). Then based on how the scheduled news transmission or surprise news transmissions worked, they would be able to present trading strategies to their customers. Profitable trading strategies are preferred by people when they work with stock analysts (Donders and Vorst, 1996; Ederington and Lee, 1996). The third reason presented by Jiang et al. (2010) is that such analysis of volatility spillovers and news announcements will throw light on the fundamentals of the situation and the volatility contagion. A volatility contagion and its definition differs across research works but it has been observed that was some consensus. Contagion is understood as a transmission of shocks in an unanticipated manner. Sometimes normal spillover effects exist and at times interdependencies in the transmission of shock because of integrated markets will also exist in parallel. In the aftermath of a news effect, the contagion is differentiated from normal issues because it is not a normal interdependency. Therefore, according to Jiang et al. (2010) it would be easy to identify and segregate the contagion effects when studies are conducted on understanding the transmissions. The final reason to study spillover effects and their relation to macroeconomic news announcements is because of how it informs market efficiency.
