Global Diversification Is Preferable
Finance theory holds that correctly constructed equity indexes will have very similar returns over long timeframes.
But the journey to this destination differs:
The narrower the index, the rockier the trip, whilst a broader approach helps smooth the journey.
A global approach is more diversified than a country-specific one.
Moreover, a global approach accounts for performance rotation.
No nation’s or region’s companies are inherently superior.
Leadership rotates—frequently.
