Though it didn't quite measure up to 2006, investors still enjoyed nice profits in 2007. With the Dow setting new highs and the S&P advancing 4.8% so far, there were plenty of gains to go around.

My head was pretty inflated. I had a nice 33% appreciation from my shares in Coca-Cola, besting rival PepsiCo's 26% gain. Kudos for my investment in 3M too, which registered a market-beating 12.5% gain in 2007.   

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 this year:

U.S. Market Company

Return Year to Date

IBM (NYSE:IBM)

16%

Hewlett-Packard

26%

Alcoa (NYSE:AA)

26%

NVIDIA (NASDAQ:NVDA)

46%

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

International Market Company

Return Year to Date

VimpelCom (NYSE:VIP)

170%

Suntech Power (NYSE:STP)

150%

Sinopec

69%

Ctrip.com (NASDAQ:CTRP)

75%

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 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.
