Not all funds obviously. I also use a boggle head portfolio so the target date funds are not much interest. For example, the total stock market index from Fidelity and Vanguard.
Also a great choice if in an account that allows ETF purchases. The point was VG forced much of the industry to at least try to offer lower cost index funds, and others have reluctantly followed.
