Recently, Foolish colleague Todd Wenning wrote that global stocks are "catching up" to our stalwarts here at home. That's not quite right. The uglier truth is that American stocks, as a group, are underperformers when compared with the wider world.

For example, the world's finest stock of the past 10 years wasn't Apple (NASDAQ:AAPL) or even Hansen Natural. (Their great 10-year returns aren't even in the same ballpark.)

So without further ado, the world's finest stock is ...

Gammon India, which -- wait for it -- rose more than 2,000 times in value for the investor who bought a position in 1996. Put more simply: A $10,000 investment made then would be worth more than $20 million today.

Meet Gammon India
Not that you'd have been able to get those sorts of returns. For one, you would have had a hard time finding Gammon India -- it had a market cap of roughly $350,000 in 1996 and traded on the Mumbai Exchange. Even if you did find it, other intricacies of investing directly on foreign exchanges, such as taxation of capital gains and currency rates, may have significantly affected your returns.

Nevertheless, there's a lesson in this 2,000-bagger that applies to any Fool. Gammon India wasn't and isn't some bubble gum-and-bailing wire outfit reminiscent of the companies that took off in the dot-com bubble. Instead, it's a civil-engineering company that was founded in 1919. Today, Gammon India is one of its home country's largest construction companies and is capitalized at more than 32 billion rupees -- roughly $700 million.

Wide world of gains
In other words, many of the world's best stocks are in relatively simple businesses through which they create extraordinary value. Sometimes, they're hidden in plain sight and are accessible to any Fool. Here's a list of superior stocks from the past decade that hail from other parts of the world but, unlike Gammon India, trade on U.S. exchanges.

Unfortunately, many of the best international stocks aren't traded as American depositary receipts (ADRs). That means you'll either have to pick them off of the Pink Sheets or open an account to invest directly in international exchanges, such as London's FTSE, Germany's Xetra DAX, or the Mumbai Exchange.

A guide for going global
Such complexity is what makes international investing both thrilling and dangerous. Getting help an excellent idea, and you have two ways to obtain it on the cheap. First, you can opt for a low-cost mutual fund with a proven track record, such as Dodge & Cox International Stock, whose largest investments include GlaxoSmithKline (NYSE:GSK) and Infineon Technologies (NYSE:IFX).

Second, and if you're in the market for higher returns than a diversified fund might provide, you can opt for a service that specializes in scanning the world for winners. Bill Mann has just launched such a service, dubbed Motley Fool Global Gains. Click here to try it free for 30 days, and you can see the team's inaugural picks. Among the other perks you'll receive is a short report on brokers with international investing capabilities and a discussion board that covers the same topic in depth.

If you want to go it alone, invest in a good screener and look for the same sorts of characteristics that the Global Gains team uses to define a great stock. Among the list: positive and rapidly growing free cash flow, multiples to earnings and cash flow that appear cheap when compared with the industry in general and rivals in particular, a clean balance sheet, and tenured management.

Stalking the 10-bagger overseas
Peter Lynch has famously advocated for buying what you know, right here in the good ol' U.S. of A. But even Lynch spent time overseas studying foreign stocks that others wouldn't buy, such as Volvo. That's a key reason why he earned better-than-29% average annual returns as the head of Fidelity Magellan.

Could similar returns be in your future? Maybe, but you'll never know for sure if you ignore what's over there in favor of what's here. So don't. Instead, get globetrotting, and you'll give your portfolio a chance to earn the 10-bagger returns it deserves.
