Η σχετική συμπεριφορά των χρηματιστηρίων της Ε.Ε. κατά τη διάρκεια της πανδημίας Covid-19

Abstract

This dissertation aims to study the behaviour of European Union stock exchanges during the coronavirus pandemic. In order to achieve the survey, daily data of the representative stock indices of all stock exchanges of the Member States of the European Union and the STOXX EUROPE 600 stock index, which is used as a benchmark, were used. The sampling period consists of January 1, 2018 until October 30, 2020. In order to understand the behaviours of stock indices during the coronavirus period, sampling is divided into three periods, which are characterized as: a) pre-crisis period, b) crisis period and c) recovery period. At the end of the research, it can be concluded that in the crisis period all stock markets show negative average returns with the exception of the Romanian stock market, which shows a positive average return. The volatility of European stock markets is higher during the crisis period than in the other two periods. In addition, the findings show that European stock markets are linked during the crisis period, as they show high positive correlations. The Romanian stock exchange is an exception here as well. Finally, as it can be seen, the German stock market was swept away by the fall of the European market during the crisis period. However, the Romanian stock market has benefited from its already existing negative correlation mainly with the market index.
