Investors were pretty sharp in 2006. As the S&P shot ahead 15% and the Dow set new highs, there were plenty of gains to go around.

My head was pretty inflated. I had a nice 18% appreciation from my shares in Starbucks. Kudos for my investment in ExxonMobil (NYSE:XOM) too, up 39%.

But my personal bubble burst when I saw what I could have gained. You may feel a little inadequate as well.

The big letdown
Consider investors who found their way into four of the more popular and better-performing stocks in the S&P 500 last year:

U.S. Market Company

2006 Return



Cisco Systems


Sears Holdings (NASDAQ:SHLD)


Boeing (NYSE:BA)


Not too shabby. But take a gander at the performance of some large, well-known international stocks:  

International Market Company

2006 Return

China Life Insurance


Millicom International Cellular


China Mobile (NYSE:CHL)


Core Labs (NYSE:CLB)


Of course, one could stack the table with any stocks to alter the comparison. But in general, great opportunities exist outside the United States. In fact, for every market-beating investment in a U.S.-based company, I'll guess that I can find an international stock that did better.

Why am I so confident? Because on average, the U.S. market isn't growing nearly as quickly as those of many foreign markets. From September 2002 to the end of 2006, 19 countries beat the U.S. market's return. And not by a nose, either -- try Hungary (up 268%) and Austria (up 375%).

It's out there -- go get it
If you truly want to own the best stocks in the world this year, you need to look globally.

But don't just buy anything. Look for the same characteristics you'd want in any U.S.-based investment, and vet your picks even more closely -- added political and economic risks demand that you do so.
