OK, the good news is that you have a whole lot of money in safe investments — chicken money.
As for the stock portfolio, here’s a wild guess — and remember “free advice is worth exactly what you pay for it!”
And also remember, that if you look back there is a 50/50 chance you could be wrong about the decisions you make today.
Still to let you sleep well at night at your stage of life and in your situation, I would put about 40% in the Fidelity Balanced Fund (FBALX), and 20% in the S&P 500 stock index fund.
Then I would put the rest in the Fidelity Government securities MM fund. That fund yields only about 1%, but will keep some money liquid for your RMDs.
That rep probably didn’t have the big picture of your other savings, so was pretty low on “stocks’ — and I think interest rates could go higher so I’d stick with the bonds in the balanced fund. You need some long-term stock exposure to keep up with inflation. So don’t panic in a market decline, just stick with the plan!
