MSCI, FTSE, S&P: Index Families

How "world" is a world ETF?

MSCI World covers 23 countries. But 73% of it is US companies (MSCI, 30 September 2026).

Add 24 emerging markets and you get MSCI ACWI: still 64% US.

FTSE All-World: about 4,250 shares in nearly 50 countries.

The S&P 500 is one country: 100% US.
