The conventional personal finance playbook for retirees with 401(k)s is to trim exposure to stocks and dial down risk as they age. But many savers over age 70 are defying that rule, packing their 401(k)s with more stocks than experts recommend, according to Fidelity Investments.
Half of Fidelity 401(k) plan participants aged 70 or older have a "higher equity allocation than suggested," more than any other age group and well above the 34% average for all ages, according to Fidelity's 1Q 2026 retirement analysis report. Similarly, nearly four of 10 401(k) savers aged 65 to 69 also have a larger helping of stocks than investment pros recommend.
