Abstract

The рurрose of this research was to examine cointegration relationships among the stock market indices before and after the global financial crisis. The cointegration effects were analysed also in the context of the COVID-19 pandemic. The sample included 20 years of data at daily, weekly, and monthly frequencies for stock рrice indices in the United States (S&Р 500), Europe (STXE 600), Japan (Nikkei 225), China (SSE composite), Australia (S&P/ASX 200), and Brazil (IBOVESPA). Two interesting empirical facts were documented. First, the global financial crisis does not seem to have played a significant and uniform role in influencing the cointegration relationship, as only for the monthly sample the number of cointegrating relationships changed after the crisis. Second, the daily sample allowed to explore the period during the COVID-19 pandemic. The findings suggest that this event increased the number of cointegrating relationships, perhaps due to the global nature of such phenomenon which affects both developed and emerging economies contemporaneously. On the other hand, the financial crisis affected mainly developed economies, and the spillovers to emerging markets took place at a later stage as a second-round effect. In line with the previous findings in the existing literature, the results of the study have shown that cointegration stock market indices is dependent on the period of analysis and the frequency of the data.
