Do you know which sector has driven much of the U.S. equity market growth since the financial crisis? The answer is technology — specifically the four technology-related platform industries of software & services, hardware, semiconductors & equipment, and media & entertainment. And they have climbed sharply across regions, with the United States leading and emerging markets keeping pace, powered by China’s ramp-up in R&D investment, and momentum in Europe, historically a step behind, from the EU’s digital transformation program. MSCI’s sector indexes provide a transparent way to track these structural shifts across countries and regions to support informed portfolio allocation decisions.
