Are International ETFs Worth It?

The Complete Answer

International ETFs are worth holding for most investors because they diversify away the risk of betting everything on a single country. US stocks have led for the past decade-plus, but that has not always been true — international markets outperformed for much of the 2000s, and leadership rotates in long, unpredictable cycles.

A single fund like VXUS gives you thousands of companies across developed markets (Europe, Japan, Canada, Australia) and emerging markets (China, India, Taiwan, Brazil) in one purchase, at an expense ratio around 0.05-0.08%. That is roughly 40% of the world's stock-market value that a US-only portfolio ignores entirely.

A commonly cited allocation is 20-40% of your stock holdings in international. Vanguard's target-date funds, for reference, put about 40% of their equity sleeve abroad. Within that band the exact number matters less than choosing one and sticking with it through stretches when it underperforms US stocks.

The honest caveat is that international has lagged the US for years, which tests patience. But diversification only helps if you hold it before you know which region will win. If you would rather not decide, a total-world fund like VT holds US and international together at global market weights and rebalances the split automatically.
