Abstract

This work aims to systematize the empirical studies on the effects of events related to the COVID-19 pandemic on stock market indices. Two conceptual frameworks are identified: capital market efficiency and behavioral finance. The literature review —at first of a systematic type complemented with a narrative one— shows that informative events can be classified into health-related (announcements by the World Health Organization, evolution of the pandemic, vaccines) and non-health-related (government measures). The analysis of stock indices shows an initial negative effect on returns and a positive effect on volatility. The comparison between developed and emerging economies shows unequal repercussions of new information.
