• The European Central Bank (ECB) reported in its May 2026 Financial Stability Review that asset price valuations have reached particularly high levels in the technology and AI sectors. • Euro area investors hold significant exposures to these sectors, with price/earnings ratios remaining historically elevated across multiple equity markets. • Data indicates that US equity indices are currently trading at notably higher valuation levels compared to European markets.
