In this paper, we extend the current literature by seeking answers to two questions: (1) were/are traditional stock markets or FinTech markets more volatile during the Russia–Ukraine War? (2) Which market returns were/are higher during the Russia–Ukraine War—traditional stocks or Fintech stocks. We explored whether cumulative abnormal returns and the stock price of the Fintech market, proxied by Global X Fintech ETF, of firms listed in 28 different countries’ stock markets differ during the Russia–Ukraine War than before the war. Our data set covers the period from June 1, 2021, through November 22, 2022. Our results found that traditional stock markets have been more volatile than Fintech stock markets during the Russia–Ukraine War than before the war. On the other hand, we can see that traditional market returns have been lower than Fintech market returns during the Russia–Ukraine war than before the war.
