Data Analysis and Visualization for Dow & Jones Industrial Average Facing COVID-19 Pandemic

Abstract

This paper investigates the Dow Jones Industrial Average performance facing the crash triggered by COVID-19. We find that all constitute stocks experienced negative returns during the peak of a collision, but different constitutive sectors show us different elasticity in responding to the crisis. There are three sectors that offer such striking performances: Technology, Pharmacy&Biotech, and Oil that we conducted most parts of the research for analyzing these sectors. The Technology and Pharmacy&Biotech sectors had a satisfactory rate of loss compared to other sectors, whereas the Oil sector’s stock values fell dramatically. The analysis reveals not only the reasons why the index and its sectors reacted differently to the crash but also how should investors or anyone interested in the stock market conduct proper investment strategies for a potential future crisis.
