Abstract As the volatility of each country's industrial stock market has increased since Corona 19, the correlation between each country's industrial stock market is growing. Since 2008, as oil prices soared, the tension in international oil supply and the seriousness of air pollution, global warming and environmental friendliness, new energy vehicles developed rapidly, and among new energy vehicles, Korea Hyundai, China BYD and American Tesla were the most famous, and therefore the COVID-19 There is a need for research on the correlation between the Hyundai, BYD, and Tesla stock markets after the war. In this study, the correlation between Hyundai, BYD, and Tesla stock markets before and after COVID-19 was analyzed using the VAR model and the shock response function. Looking at the empirical analysis results of the VAR model and the shock response function, it can be seen that the correlation between Hyundai, BYD, and Tesla stock markets after COVID-19 is stronger than before COVID-19. Tesla, in particular, is strengthening its links to the other two markets.
