An interesting article in Smart Money (subscription required for online version), discussing The Next Frontier.  As the article notes:

“…finding investing opportunities sheltered from the fits and starts of the global economy requires going off the grid. Way off, in fact. Countries like Nigeria, Kazakhstan and Qatar are developing tradable markets, prompting adventurous investors to break out their pith helmets.

“People have become more and more comfortable investing outside the U.S.,” says Todd Henry, emerging-markets specialist at T. Rowe Price. “Now people are saying, ‘Where else can we go?'”

It goes one to discuss markets such as Jamaica, Mauritius, and Lithuania and contrasts the growth in such frontier opportunities versus the more traditional emerging markets such as Brazil, India, and China.
