As you age and get closer to retirement, you dial down your equity allocation as you move money to fixed income. The rule of thumb has its limitations, but in the absence of knowing more about someone, their risk tolerance, and their cash flows, it does a good job of guiding people towards the right investment mindset and outcomes. Most “Target Date” retirement funds work this way. But today, I want to challenge one aspect of the rule of thumb, and that is that we got the type of fixed income wrong. It should be annuities, not bonds.
