Dopady geopolitické nejistoty na vybrané akciové trhy

Černý, Ondřej

This thesis examines the impact of geopolitical uncertainty on four selected stock markets. We analyse the effect on stock market volatility and returns using the GARCH and the EGARCH models and daily stock returns and GPR index value. Furthermore, using categorical indices GPA and GPT, we inspect whether the effect of uncertainty caused by threats differs from that caused by acts. Additionally, we examine whether the impact changed between the period before and after 9/11. The main findings from our results suggest that a rise in each of the risk indices, i.e. global GPR, GPA and GPT, increases the volatility of all of the stock markets and the returns of the two. Also, geopolitical threats negatively influence Hong Kong stock returns, whereas geopolitical acts do not impact them. Furthermore, the impact of at least one of the uncertainty on stock return or volatility changed in the case of all the selected stock markets.
