Some here have suggested instead of Individual Bonds I should look for Bond Funds. I've looked into Guggenheim BulletShares and Fidelity Defined Maturity Funds. What I'm not clear on is the timeline for starting compared to the return. In the last 12 months Fidelity closes the fund to new investors. But if I'm looking at a 3 year or even 5 year timeline won't I miss out on significant gains using one of these predefined bond ladders?
For example, Fidelity 2017, inception date was in 2011. So, even though 2017 is a good timeline for me, won't the returns be tapering off in the remaining years? At what point after Inception does it make no sense to go this route?
