Funds of growth and core stocks outpaced more conservative value funds, while midcap companies outperformed both large- and small-cap funds. Midcap core funds had the best average return, 10.72 percent, followed by midcap growth funds at 10.36 percent.
Bear market funds, which hedge against market downturns, saw the slimmest returns, an average of 2.56 percent year-to-date, while S&P 500 index objective funds, which attempt to replicate the returns of the index itself, posted an average 4.87 percent return.
''I think you saw a lot of fund managers latch on to the stock market's momentum in the fourth quarter, and that helped boost returns," said Bill Sickles, senior research analyst at Lipper. ''And the midcaps were good for investors looking for more nimble companies, but without the risk that goes with small-caps."
November's strong run-up in stocks helped mutual funds to modest fourth-quarter returns despite Wall Street's December malaise. US diversified equity funds saw an average return of 2.64 percent for the quarter. Again, growth stocks led the pack in returns, with small-cap funds lagging and bear market funds posting negative returns.
Sector-specific funds, which focus on stocks within a selected industry, saw average 2005 returns of 11.5 percent, much of that attributable to sharp gains in energy and utility stocks. Natural resources funds, which include oil and gas stocks, saw average returns of 40.86 percent for the year, although they posted negative returns of 0.68 percent for the fourth quarter as oil prices fell. Likewise, utility funds saw average annual returns of 13.94 percent, though quarterly returns fell 4.14 percent.
International funds sharply outperformed domestic funds in 2005, as strong economic growth in Latin America, Europe, and Japan fueled stock prices there. Funds investing in Latin American stocks saw an annual return of 53.67 percent, followed by Japanese-focused funds with an average 2005 return of 34.6 percent.
For the fourth quarter, a surge in the Tokyo stock markets helped Japanese funds to an average return of 18.46 percent, while the run-up in gold prices pushed international gold funds to a 14.89 percent average return.
