Where I Disagree with Nobel Prize Winner Eugene Fama
Posted October 24, 2013on:
OK sure, I can understand his point. Why invest outside of the US when the US markets already account of 40% of world capitalization? “The U.S. market is so well-diversified already that combining it with global markets doesn’t really matter,” so said Fama.
However, I think it actually does matter ….
Proportionally, the US market is getting smaller. Right after the second world war, the US market accounted for 70% of world capitalization, now it only accounts for 40%. For a country that boasts only 5% of of the world’s population, this is still exceptionally high.
For the foreseeable future, there are better than even odds that the combined markets outside of the US will grow faster than the US market will do alone. Why forego those opportunities?
The diversification benefit you’d get is certainly not negligible either. During the so-called ‘lost decade’ of 2000 to 2009, the US market, as measured by the S&P 500, had a net loss of 9.1%, while international developed markets went up by an anemic 12.4%, but emerging markets went up by a whopping 154.3%.
It would have made a bog difference if you have a piece of emerging markets in your portfolio.
