Stocks from developing countries have rallied strongly, but there still are opportunities to make money in this sector -- if you can handle the volatility. By Steven Goldberg, Contributing Columnist July 20, 2009 Emerging markets are on fire. From March 2 through July 15, the MSCI Emerging Markets index advanced a staggering 61% -- the sector's strongest rally ever over so brief a period. Is it too late to hop aboard? Keep in mind that the index plummeted 65% from October 29, 2007, until March 2. That means emerging markets are still trading at little more than half their value of 18 months ago. As for valuation, the MSCI index trades at about 13 times operating earnings for the past 12 months, according to Thomson Reuters I/B/E/S. "Emerging-markets stocks, in general, aren't cheap, but they aren't expensive," says Chris Laine, one of six managers who steer SSgA Emerging Markets (symbol SSEMX). "The easy money has been made."But emerging markets are growing while the developed world is not. Analysts who track emerging-markets stocks estimate that earnings will rise 7% to 10% over the next 12 months. Amid the worst global recession since the 1930s, those numbers are enticing -- even if, as so often happens with analyst forecasts, they turn out to be overly optimistic. Patient investors have been amply rewarded. The MSCI Emerging Markets index returned an annualized 9% over the past ten years through July 15, compared with an annualized 2% loss for Standard & Poor's 500-stock index. But virtually everyone who has ever put a nickel into emerging markets bears battle scars. In 1997-98, for instance, the MSCI index tumbled 57%, largely because currencies of one emerging country after another collapsed during the "Asian contagion." The trick in this dicey sector is to hold on -- regardless of the short-term pain. "Unless you're a gun-slinging hedge fund, emerging markets are not where you want to trade," Laine says. Advertisement Volatility comes with the territory. Even though many developing economies are arguably much healthier financially than the U.S., their stocks fell far more than ours did last year. The reason? Investors view emerging markets through two separate prisms. On one hand, they see some of the world's fastest-growing economies. On the other, they see some of the riskiest stocks on the planet. When stocks in developed nations rise or fall, emerging-markets stocks usually do the same-but much more so. Emerging markets are tethered to the developed world. The commodity-producing countries, such as Brazil and Russia, thrive when the global economy is robust enough to devour more and more oil, gas and other natural resources. The manufacturing countries, mainly in Asia, count heavily on exporting their products to the U.S., Japan and other developed nations. China, now the world's third-largest economy, and other emerging markets boast burgeoning middle classes, who can afford more consumer goods and services. That's a welcome trend. The world desperately needs Chinese consumers to spend more and U.S. consumers to save more. Emerging markets pose special risks. Companies often don't treat shareholders as owners. A company, particularly one partly owned by the government, often has higher priorities than rewarding shareholders. It's also difficult to obtain solid information about companies in emerging markets. Politically, the dangers of revolutions, coups, government defaults and nationalization are much greater in emerging markets than in the developed world.

I think most investors -- except those with short time horizons -- should keep roughly 10% of their stock money in emerging markets. Five first-rate funds How to invest? Start by avoiding almost all narrowly focused country and regional mutual funds and exchange-traded funds. A diversified emerging-markets fund will give you all the thrills and spills you can handle. I fail to understand what makes people think they can predict what will happen in India better than they can guess the future for, say, Target -- where they may shop regularly. You can choose from several outstanding funds. SSgA Emerging Markets picks stocks primarily using sophisticated computer programs. The fund has essentially tracked the MSCI index over the past ten years. T. Rowe Price Emerging Markets (PRMSX), with an identical expense ratio of 1.24%, has beaten the index by an average of one percentage point per year over the same period. Fans of index funds are well served by Vanguard Emerging Markets Stock Index (VEIEX) or Vanguard Emerging Markets Stock ETF (VWO), which charge annual fees of 0.32% and 0.20%, respectively. Advertisement If you use an adviser, American Funds New World A (NEWFX) is a unique offering. It keeps about 25% of its assets in multinational companies that do a lot of business in emerging markets-and usually holds some emerging-markets debt as well as stocks. Over the past ten years, it has trailed the MSCI index by about half of a percentage point per year but has exhibited 20% less volatility. That's a big plus in a sector in which hanging on during rough markets can be the hardest part of the game. Steven T. Goldberg (bio) is an investment adviser and freelance writer.
