Abstract

Under the dramatic impact of Covid-19, the global economy has decreased sharply, and many countries have experienced negative economic growth during the pandemic. This study uses Fama and French Five-Factor model to investigate the reasons causing these changes and provide referential suggestions on how to invest in stocks of the medical industry during black swan events. Based on the Fama-French five-factor model and data selected from the Center for Research of Security Prices (CRSP), this article explains stocks return in the medical field from May 2019 to February 2020. Specifically, the detailed influence of Covid-19 in health, medical equipment, and drug industries is analysed according to market risk premium, size, book-to-market value, profitability, and investment. The result shows that βMKT becomes larger and βSMB becomes smaller in Health Industry. Meanwhile, βHML in Medical Equipment becomes insignificant and βRMW becomes significant after COVID-19. And the result of drugs shows the βSMB is larger than 1, which indicates investment in a small value company is better. For the whole Medical field, low-profit stock portfolios are profitable.
