In this Investment News article (http://www.investmentnews.com/article/20101003/REG/310039997#), several funds from the American Funds and Fidelity are the most popular funds in 401k plans at the time of the study. Due to the size of many 401k plans it is not surprising to see larger fund families making the list.
Hi Julianne,
By 'top funds' do you mean most popular or best returning? Please keep in mind that neither size/frequency of use nor performance necessarily dictate that the funds are appropriate for your plan, or would, for that matter, work well with one another.
