Mr. Kroijer,
All countries are not the same. All stock markets do not work efficiently. If the market were truly efficient in pricing, the Great Recession would not have occurred, since the value of financial instruments would have been reflected in stock prices in an ongoing basis. Geopolitical risk and corruption are not the same in every country. As a world citizen, you would be aware of the different business practices that occur in Denmark, the U.S., and U. K., relative to China, Russia, or Nigeria. Allocating capital based on market capitalization with no regard to any other factor does not make sense.
