International ETFs: What Diversification Outside the U.S. Adds

A broad ex-U.S. fund can combine developed and emerging markets, while other ETFs cover only one region, country, size segment, or factor. Read the benchmark description before assuming two international funds are substitutes.

Vanguard describes VXUS as tracking the FTSE Global All Cap ex US Index, which includes developed and emerging markets outside the United States across market-cap sizes.

International holdings can reduce dependence on the economic, valuation, sector, and company composition of one country. Diversification cannot prevent losses, and global markets can decline together.

The allocation decision should be based on the desired global exposure and the investor’s full portfolio rather than a forecast that one region is about to outperform.

When an unhedged international fund’s holdings are translated into U.S. dollars, currency changes can add to or subtract from the local-market return. Hedged funds use a different implementation and cost structure.

Foreign taxes may be withheld from dividends. Whether an investor can claim a foreign tax credit depends on account type and tax circumstances; fund reports and tax documents should be reviewed rather than assuming full recovery.

Check developed/emerging coverage, small-cap inclusion, country and sector weights, index provider, expense ratio, spread, securities-lending policy, domicile, and tax documents.

Avoid accidental duplication: a total-world fund already includes U.S. and international stocks, while a total international fund is designed to complement rather than replace U.S. exposure.
