I'll cut right to the chase: International stocks will do wonders for your portfolio.

If you're anything like me -- a U.S.-based retail investor looking for stocks to help build a comfortable retirement nest egg -- you need to look abroad for stock investments.

Perhaps you already have ...
It's not because you need them for diversification. My colleague Todd Wenning showed that the correlation between U.S. and foreign stocks has become quite close. No, you need them for the incredible growth potential they pack -- growth that, in some cases, you won't find anywhere here in the United States.

Consider these incredible performers in 2007:



2007 Return


Shanghai Stock Exchange Composite



Bombay Stock Exchange





Hong Kong

Hang Seng Index


South Korea

Seoul Composite


For comparison, the Dow came in 11th at 6.4% growth and the S&P 500 came in 13th with a 3.5% return.

There are many pearls to uncover
If you'd listened to the media up through the beginning of 2008, you may have had the impression that China was the only hot economy. While China did crowd the list of top-performing "world stocks" in 2007, if you'd focused on that country alone, you would have missed out on these top returns.

Where do we go now?
While U.S. markets have wiped out all the gains made by the last bull market over the past five years, international bourses in Norway, Denmark, Spain, Greece, and elsewhere have still preserved investors' gains.

Compare AstraZeneca's returns this year to Schering-Plough (NYSE:SGP), which has lost nearly 40% of its value. Contrast the gains Fairfax Financial has made with the government-orchestrated takeover of American International Group (NYSE:AIG).

Predictably, what was good last year hasn't been good this year. It was a similar story the previous year: Whereas Peru, Venezuela, and Vietnam were the top three performers of 2006, they fell to 14th, 79th, and 22nd place, respectively, toward the end of last year. While China was good to investors, returning more than 95% in 2007 and roughly 130% in 2006, it has been hit especially hard in 2008.

And even though the index has struggled, some individual companies have been brought down to levels so appealing that Motley Fool Global Gains advisor Bill Mann called the recent sell-off in China the investment opportunity of a lifetime.

So the lesson isn't that you should -- or shouldn't -- invest in China ... necessarily. The point is that international stocks will do wonders for your portfolio. Ignoring them is unwise.

The Foolish bottom line
For too long, adding an EAFE (Europe, Asia, Far East) index fund was as close as one could get to going global. These days, you can find regional and even country-specific funds.

Investing in international stocks is no different from investing in domestic stocks. Don't try to predict the next hot trend. Instead:

  • Invest in businesses, not stocks.
  • Pay close to attention to valuation -- i.e., don't overpay for a story.
  • Stay diversified.
  • Be patient, and have fun.

Just promise me you won't try to predict the next big winner from the headlines. Focus on fundamentals, competitive advantages, growth prospects, and, as ever, valuation.
