For those readers who embrace my CORE and EXPLORE approach (this is actually my version of John Bogle’s approach) with respect to Asset Allocation, you can see why I suggest considering country funds for a small percentage of your EXPLORE portfolio. Country funds fulfill the cardinal rule of diversification as their correlations to the USA markets are much lower. Over the past 30 years, the world’s top performing market has come from this group 100% of the time (outside the USA).
