Abstract

International diversification has hurt US-based investors for over 30 years, but the long-run case for it remains relevant. Both financial theory and common sense favor international diversification, which is buttressed by empirical evidence that is very supportive at longer horizons and for active strategies. Finally, it would be dangerous to extrapolate the post-1990 outperformance of US equities, as it mainly reflects rising relative valuations. If anything, the current richness of US equities may point to prospective underperformance.

国际多元化——这么多年过去了仍然不疯狂

30多年来，国际多元化一直在伤害美国投资者，但长期来看，这一点仍然重要。金融理论和常识都支持国际多元化，这一点得到了经验证据的支持，这些证据在长期来看非常支持积极的战略。最后，推断1990年后美国股市的跑赢表现是危险的，因为这主要反映了相对估值的上升。如果说有什么不同的话，那么目前美国股市的丰富性可能预示着未来的表现不佳。
