Domestic vs International Stocks

Compare US (domestic) and international stocks — concentration risk, diversification, and long-run performance.

Overview

The US accounts for roughly 60% of global market cap, so an all-US portfolio is concentrated in one country. International stocks add geographic diversification, currency exposure, and access to economies the US market doesn't cover. Returns trade leadership across decades.

Choose Domestic Stocks when...

You will always hold domestic — the question is the weight. Heavier US allocations are reasonable but 100% US ignores 40% of the global market.

Choose International Stocks when...

Add international exposure for diversification, lower correlation, currency exposure, and access to companies and economies absent from US indexes.

Our Verdict

A globally diversified portfolio holds both. Market-cap-weighting puts you at roughly 60% US / 40% international; many US investors home-bias to 70/30 or 80/20. Avoid 100% US — the post-2010 outperformance is one decade in a long history of leadership rotation.
