The study contains the results of the efforts to identify the stock markets reaction to the emergence of a pandemic in 2020. For the comparative analysis, daily data on the closing stock indices prices of the Russian Federation and the United States of America were used. Based on the conclusions of the comparative and graphical analysis, the main two hypotheses were tested about the significance of the unique crisis, which led to large-scale changes in the economy of many countries, including the transformation of financial markets. The relevance of this work lies in identifying the potential for building new research chains to detect and analyze other factors that affect the behavior of a wide range of markets in developing and developed countries during economic decline.
