More than half of the world's market cap now sits outside the United States, and the largest IPO in history now belongs to a Chinese bank, ICBC. This distinction could be temporary, depending on how Japan proceeds with its postal savings bank. Either way, it means that many of the world's most established and dynamic growth opportunities are not American companies.

Scouring the globe for value
Successful international investing requires many of the same skills required to evaluate a U.S. company. But in addition to understanding the fundamentals of a business, international investing requires us to grasp economic policy, political currents, corporate governance, accounting standards, and cultural factors in the countries in question -- things we take for granted here in the U.S.A. In our recently launched Motley Fool Global Gains service, we take these factors and others into account in our international search for the most attractive opportunities for subscribers.

I don't have a handful of thoroughly researched ideas to offer you here, but I am having fun mining our new Motley Fool CAPS service for other investors' opinions. CAPS is a community intelligence database that asks investors to rate stocks. In turn, every investor is ranked, as is every stock. As more people participate and more time passes, we hope we'll be able to find the best investor and best stock in the United States -- and, potentially, the world. (Admittedly, we'll have to roll this thing out of beta testing before we can start talking about global domination.)

Six all-star foreign companies
The following three stocks all have been recommended by at least 10 CAPS participants, have a P/E below 20, a market cap of more than $10 billion, and are rated the maximum five stars by the CAPS community. As you'll see, there are some easily recognizable names on the list.

And the following three companies have all the same qualities as the companies above, but have market caps of less than $8 billion. As you might expect, these companies aren't exactly household names.

In CAPS, you'll also find ratings on all of the exchange-traded funds that track the markets around the globe. In some cases, it's easiest to gain exposure to the Swiss economy, for example, with the iShares MSCI Switzerland Index (AMEX:EWL) ETF. 

When you go digging for the world's best stock ideas in a volatile market, it's still crucial to do your due diligence.
