Assessing the Impact of the COVID-19 Pandemic on the Greek Energy Firms: An Event Study Analysis

This study examines the impact of the COVID-19 pandemic on the stock returns of 11 Greek energy listed companies. Using an event study approach covering a window of 10 days before and 10 days after the general lockdown (23/3/2020), we show that the pandemic influenced returns of the majority of the listed energy firms. However, diverging from the event day sees the negative effects dissipating.
