Inside the “Zelensky Moment”: What European Investment Patterns Reveal About Geopolitical Risk

The study: This graph shows the percentage change in defense stock investments by all investors in their sample in the period after 2019Q2 (Zelensky’s election as President of Ukraine) up to 2025Q2, compared to 2010Q4 to 2019Q2. The authors distinguish between the buckets “>100” indicating a more than 100% increase, “(0,100]”, which indicates more than zero and up to 100% increase, and “(-50, 0]” indicating a decrease less than −50% up to zero.
The study: Relative changes in defense holdings.
This figure shows the total investments in defense stocks each quarter, scaled by their total market value for two groups: Former Iron Curtain countries (Bulgaria, Croatia, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia, Slovenia) and all Other European countries in their sample. For comparability purposes, both time series are indexed such that 2014Q1 equals 100.
