ABSTRACT

Because of the Covid pandemic, the financial market, particularly the stock market, suffered a significant decline. The stock market peaked on February 19, 2020, just before the COVID-19 epidemic resulted in a precipitous decline in share prices. During the crisis, several sectors demonstrated a high degree of interdependence, which piqued our interest and prompted us to look into it further. As a result of the findings, the dependence structure between sectors is relatively similar during the pre-pandemic and post-pandemic periods, with relatively fewer linkages between sectors. The dependence of the industrial sector index has also risen and fallen in varying degrees over time. However, when the world is experiencing a COVID crisis, the performance between sectors is much more consistent, with certain sectors demonstrating stronger connections than others.
