Among the most popular funds, a few still make sensible choices. Consider American Funds EuroPacific Growth ( AEPGX). Although the portfolio is large, the performance has not shown signs of slowing down. During the past three years, the fund lost 4.7% annually, outdoing 93% of its foreign large blend competitors. Because they can invest in markets around the world, the portfolio managers should be able to find enough top stocks to fill the portfolio. The expense ratio is 0.85%, compared to an average figure for the category of 1.51%. Another safe selection is the Fidelity Spartan 500 Index ( FUSEX), which tracks the S&P 500. Because they simply mimic the benchmark, giant index funds deliver the same results as small ones. Fidelity only charges an expense ratio of 0.10%, one of the lowest fees available among 401(k) choices.
