Global Investment Returns Yearbook 2025

The Global Investment Returns Yearbook, compiled by Professor Paul Marsh and Dr. Mike Staunton of London Business School and Professor Elroy Dimson of Cambridge University, has established itself as the definitive source for analyzing the long-term performance of global financial assets. The 2025 edition, launched by UBS Investment Bank and the Chief Investment Office of UBS Global Wealth Management, represents a milestone as it allows us to compare the market performance of the first quarter of the 21st century with that of the 20th century.

The Global Investment Returns Yearbook leverages 125 years of historical data to provide investors with unprecedented insights to help them navigate current market issues. In light of increasing market concentration and correlation, this year's Yearbook includes a special chapter on global and multi-asset diversification.
