The Impact of the Obama and Trump Presidential Election Cycles on the S and P500 奥巴马和特朗普总统选举周期对标准普尔500指数的影响

ABSTRACT. The relationship between the US presidential election cycle and the S&P500 index is examined in this paper. We focus our attention on President Barack Obama and President Donald Trump presidential election cycles, as there is a research gap examining these two presidency periods. A comparative study is limited as Obama served two terms in office while Trump only one. Daily data from January 20, 2009 to November 16, 2020 was analysed. The selected dataset covers Obamas two terms and Trumps single term in office to examine cointegration (long-run relationships) and volatility dynamics exhibited by the S&P500. The study is framed around economic and political uncertainty that was captured by the US Economic Policy Uncertainty index (EPU). The ARDL, the LASSO and the GARCH models were implemented to facilitate the analysis of long-run dynamics, and volatility patterns, and to deal with modelling over parameterisation issues. The results suggest the existence of a long-run relationship for both the Obama and Trump administrations, showing that the EPU index could be connected to the behaviour of the S&P500. The long-term association between political uncertainty and the performance of the S&P500 offers insights into the importance of monitoring market volatility during presidential cycles as investors can generate profit and losses derived of markets reactions to the presidential cycle, suggesting the importance of an active portfolio management strategy during times of election. The research findings indicate low-levels of volatility persistence registered during Obamas second presidential cycle. Higher levels of market uncertainty were identified during the first cycle, results that are not surprising, as the Obamas first term in office was impacted by the global economic and financial crisis. This period was characterised by a delicate economic and financial climate, followed by government active intervention to address the effects of the crisis. In the context of the Trump admin- istration, his single term in office was shaken by the outburst of the global health crisis. Volatility persistence levels exhibited during Obama's first term in office were manifest again towards the end of Trump administration, mirroring the impact of the new health crisis and the administration lack of strategy and incoherent approach to the domestic and international impact of COVID-19.
摘要本文考察了美国总统选举周期与标准普尔500指数之间的关系。我们把注意力集中在巴拉克·奥巴马总统和唐纳德·特朗普总统的总统选举周期上,因为对这两个总统任期的研究存在空白。奥巴马担任了两届总统,而特朗普只担任了一届总统,因此比较研究是有限的。分析了2009年1月20日至2020年11月16日的每日数据。所选数据集涵盖奥巴马的两届任期和特朗普的单届任期,以检验协整(长期关系)和标准普尔500指数表现出的波动动态。这项研究是围绕美国经济政策不确定性指数(EPU)所反映的经济和政治不确定性进行的。实施了ARDL、LASSO和GARCH模型,以促进对长期动态和波动模式的分析,并处理建模而不是参数化问题。研究结果表明,奥巴马政府和特朗普政府之间都存在一种长期关系,表明EPU指数可能与标准普尔500指数的表现有关。政治不确定性与标准普尔500指数表现之间的长期联系,让我们深入了解了在总统选举周期监测市场波动的重要性,因为投资者可以根据市场对总统选举周期的反应产生利润和损失,这表明了在选举期间积极的投资组合管理策略的重要性。研究结果表明,在奥巴马的第二个总统任期内,波动性持续保持在低水平。在第一个周期中,市场的不确定性水平较高,这并不令人惊讶,因为奥巴马的第一个任期受到了全球经济和金融危机的影响。这一时期的特点是微妙的经济和金融环境,随后是政府积极干预,以应对危机的影响。在特朗普政府的背景下,他的单一任期因全球卫生危机的爆发而动摇。奥巴马第一个任期内表现出的波动持续程度在特朗普政府任期结束时再次显现出来,反映了新的卫生危机的影响,以及政府对COVID-19的国内和国际影响缺乏战略和不连贯的方法。
