How about putting 1/2 your money in Fidelity Freedom fund and 1/2 in Vanguard Target Retirement fund? I've been looking at the Freedom 2035 and the Target Retirement 2035....the former has expense ratio of 0.78%, the latter has 0.21%, so a half-and-half should have around 0.5% which I think is acceptable for an overall portfolio.
The Freedom funds are actively managed, the TR funds are passive (index). Supposedly there are times when active funds do better than passive, and vice-versa. Seems like splitting funds between the two wouldn't be a bad idea. Then you have two teams of professionals (Fidelity and Vanguard) with different approaches working for you.
If you have Freedom funds in your 401(k), you could open a Roth IRA at Vanguard for the TR funds.
I think this plan sounds so good that I'm going to do it!
