More than half of the world's market cap 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 understanding some of the things we take for granted here in the U.S., because we live and breathe them. A few of these factors are economic policy, political currents, corporate governance, accounting standards, and cultural factors. In our recently launched Motley Fool Global Gains service, we take these factors and others into account to scour the earth looking 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 to see what other investors are thinking. What is Motley Fool CAPS, you ask? It's a community intelligence database that asks tens of thousands of investors to rate stocks to outperform or underperform the market. In turn, every investor is ranked, as is every stock. So as more people participate and more time passes, we hope to be able to determine the best investor and the best stock in America -- 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 PE below 20, a market cap of more than $10 billion and are rated as five-star picks (the highest possible) 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, but have market caps of less than $10 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 is easiest to gain exposure to the Taiwan economy, for example, with the iShares MSCI Taiwan Index (AMEX:EWT) ETF.
