NEW YORK ( TheStreet) -- Frightened by slowing global growth and the European debt crisis, investors dumped emerging market stocks last year. Diversified emerging markets funds dropped 19.9%, according to Morningstar. That was a disappointing performance in a year when the S&P 500 gained 2%. Should you avoid the emerging markets? Probably not. For starters, stocks in the emerging markets remain reasonably priced. According to Morningstar, portfolios of emerging markets funds have a price-earnings ratio of 14. That's less than the figure for U.S. funds. In addition, many countries in Asia and Latin America are continuing to report healthy growth. The emerging markets now have a long track record for delivering strong market gains. During the past decade, emerging markets funds returned 12.8% annually, outpacing the S&P 500 by about 10 percentage points. While the case for investing in emerging markets is compelling, you should not forget that markets in China and Brazil have often taken investors on rough rides. During the downturn of 2008, emerging markets funds lost 54.4%. More volatility seems likely as investors worry about slowing growth in Asia and the threat of inflation in Latin America and other regions. To limit risks, consider emerging markets funds that follow conservative strategies. Some of the cautious funds reduce volatility by focusing on companies with rock-solid balance sheets, while other portfolio managers hold some bonds along with stocks. For a fund that only buys steady stocks, consider Wells Fargo Advantage Emerging Markets Equity ( EMGAX). Portfolio manager Jerry Zhang favors highly profitable companies that dominate secure niches. To limit risk, he avoids paying sky-high prices. "We want companies that can sustain high returns on capital for long periods," says Zhang. Zhang's cautious approach has excelled in in bear markets. The fund outpaced most competitors during the downturns of 2008 and last year. During the past five years, Wells Fargo returned 6.4% annually, outdoing 94% of competitors. Worried about overheated real estate markets, Zhang is avoiding Chinese banks and property developers. Instead, he owns China Mobile ( CHL), the country's dominant cellular provider with 600 million customers. As a mature business, the company can only grow about as fast as China's GDP, says Zhang. But it is very profitable and only sells for a price-earnings ratio of 10. He also likes Taiwan Semiconductor ( TSM), a dominant producer with fat profit margins.
