NEW YORK ( TheStreet) -- For much of the past decade, small-cap stocks have outperformed large caps. But that could be changing. During the past three months, small growth funds lost 17%, lagging large growth by six percentage points, according to Morningstar. Can large stocks continue outpeforming? Yes. Large stocks are cheaper than small ones. And big stocks tend to excel when markets face the kind of uncertainty that now plagues investors.With markets favoring companies that can grow in a harsh time, large growth funds have been standouts this year, outdoing large value by a percentage point. To benefit from a revival of large stocks, consider buying a top large-growth fund. Strong choices include Buffalo Growth ( BUFGX), TCW Select Equities ( TGCEX), and T. Rowe Price New America Growth ( PRWAX). In the first quarter, large stocks lagged as investors bet that shakier small stocks would benefit from an economy that seemed to be gaining momentum. Then in the spring, economic indicators turned sour. Worried that unemployment could surge again, investors sought safety in big blue chips. When small-cap funds turned down in May, large-cap funds lost less, and they have held their lead since then. >> Get your mutual funds news on the go with TheStreet's iPad app. Even after a period of outperformance, large caps look like relative bargains.
