Domestic stocks enjoyed a profitable 2006, but the year proved even better for international equities. Indeed, international stocks outperformed the S&P 500 for the fifth consecutive year. That fact hasn't been lost on investors -- inflows into emerging market funds topped the amount that flowed into domestic funds in 2006.

Foreign stocks have been hot over the past few years, but they seem to have cooled a bit in recent months. Still, that shouldn't be a problem. As long as you devote approximately 20% of your portfolio -- diversified among equities from developed countries and emerging markets -- to international stocks, you will benefit over the long term, despite the ebbs and flows of individual markets.

A simple allocation strategy
When allocating to international stocks, investors should aim to do the following:

  1. Balance your stock selections among both large-cap stocks and small-cap stocks.
  2. Look for stocks in developed countries such as France and Japan, as well as emerging markets such as India and Brazil.
  3. Pay attention to valuations, just as you would with domestic stocks.

This last point is particularly significant, since international stocks have had a great run over the past five years. Discerning investors can still find good values, however. In a recent article in The New York Times, Paul Lim notes that "valuations are still lower outside the United States." And Bill Mann, in a recent issue of his Global Gains investment service, has also noted several undervalued markets.

The proof of the pudding is in the eating
We used this broad-based approach to picking international stocks for The Motley Fool International Stock Report, published in March 2006. Our selections and subsequent returns are provided below:

*Calculated from March 13, 2006, to May 11, 2007, including dividends.

As you can see, we were able to outperform the global MSCI EAFE index by 11 percentage points, and our domestic S&P 500 by 23 percentage points by balancing large caps such as AstraZeneca and Sanofi-Aventis with more volatile small caps such as Gruma and Flamel. As one of the editors for the report, I can say that we hunted for stocks with compelling valuations -- though I confess that there was disagreement about Baidu even before it doubled last year.

It's difficult to know what the next year will bring for this basket of stocks. Take BP, for example. Despite its lackluster performance in the past year against industry titans ExxonMobil (NYSE:XOM), Sunoco (NYSE:SUN), and Chevron (NYSE:CVX), it remains well positioned to take advantage of strong long-term demand for energy products worldwide. Furthermore, the appointment of Tony Hayward as the company's new CEO could be a catalyst here.

On the same note, AstraZeneca has trailed many of its American counterparts like Merck (NYSE:MRK) over the past year. Is it in store for a rebound? The recent addition of MedImmune (NASDAQ:MEDI) may fuel its growth in coming years.

There's no need to see the future
These 12 stocks outperformed because we looked for good companies trading at the right prices. As you search for international stocks for your own portfolio, keep these guidelines at the front of your mind.
