The Corporate Response Tracker (CRT) is designed to monitor how major European firms — specifically the STOXX EUROPE 600 — are adjusting their investment footprints in the United States in response to evolving geopolitical, regulatory, and economic signals. Initially, the CRT looks at corporate investment decisions following President Trump’s April 2025 tariff announcement. The goal is to provide a timely and accessible snapshot of transatlantic corporate sentiment and strategic alignment.
