Sorry for the blank response, clicked the wrong box.
In responding to your original question I think I am weaker at identifying long term solutions and better at making adjustments along the way to make money. For the past 2 years CDs and MM both paid 5%+ until just recently, ETFs have been very strong performers and within the past 6 months dated retirement funds and a dividend index fund have come back to life for us so shifted some MM to those categories this year. Our bills are paid with SS and a pension with a bit left over that I expected to expire in about 7 years. Starting year 6 of retirement and that "bit left over" is still there in full, so maybe it will last 6 years until RMDs.
My own goal is not to be in sub 5% investments. Expect to see rates on MM, CDs and Treasuries continue to slide for now, so will probably convert maturing CDs/Treasuries to dated retirement funds/ETFs with YTD returns ranging from 11%-27%. Not looking to purchase bonds, have enough exposure in dated retirement funds. MM compund yield just fell to 4.79% compound yield but will keep that ballast for now. Did shift some MM to settlement fund so we can act when the market has a drop.
So far we are performing beyond our projected income projections, so satisfied with that.
