Abstract

The paper investigates the impact of the COVID-19 pandemic, using the event study approach for the Bucharest Stock Exchange, by which Bucharest Stock Indices and listed firms grouped by sectors were analyzed. The paper uses three important event days, 20 January 2020, 11 March 2020, and 15 March 2020. The findings demonstrate that initially investors were not concerned about the pandemic, showing that they did not realize the extent of globalization and transmission of events on financial markets. Both after 11 March and after 15 March 2020, stock indices have declined, investors becoming worried about the prospects of their dividends and the stock liquidity. The most affected sectors were those related to metallurgical industry, IT&C. After the lockdown, there was a reversal for some sectors like pharmaceutical and biotechnology, electricity production, transportation and distribution, and IT&C. Understanding the intensity and direction of the link between some sectors and indices may influence investment strategies and help in hedging, especially in times of pandemics.
