Abstract

This study examines the short-term stock market response of eleven Greek energy firms to the April 2, 2025, U.S. tariff announcement. Using an event study methodology over an 11-day window, results reveal limited reaction on the event day but significant negative abnormal returns in the days that followed. A temporary rebound occurred, though not sustained. The findings highlight the sensitivity of small-market energy firms to international trade policy shocks, even when not directly targeted.
