I asked this in another forum and did not get much of a response so I thought I would try here.
I retired 12/31 and am in the process of rolling over my 401k to my Fidelity IRA and reallocating the investments. Targeting a 60/40 split.
What is the best way to invest the bond allocation? Single Bond fund, multiple bond funds(type/duration), individual bonds?
"Best" is going to be a slippery concept. But here's what David Swensen, the former manager of the Yale University endowment fund, would have suggested as an example of something smart.
First, he'd say rather than 40% in bonds (which will mean a certain percentage in corporate bonds which do force you to bear risks), he'd say 30% in US Treasuries (which theoretically let you avoid risks).
Second, he'd have you put half of that 30% into a intermediate term Treasury bond fund (ideally one where duration of fund matches duration of market)... and then other half into a TIPS fund so you have some real assets to protect you against inflation.
So, two funds or ETFs.
This is what I do, for what that's worth.
P.S. If you have taxable and tax-deferred, I think bonds go in the tax-deferred space. Reason: Because if you put a stock fund in the taxable space, you'll get qualified dividends tax treatment and long-term capital gains treatment. Also if you want to look really long term, your heirs will get the Section 1014 step-up in basis.
