Casual Investing for Your 90s (Ages 90-99)
- One-fund portfolio: Continuity matters more than optimization. Common mistake: Switching funds in a taxable account to tidy things up and realizing large long-term gains, when holding the shares until death would have given heirs a stepped-up basis.
- 30 minutes a year: Thirty minutes may be more than the routine needs. Common mistake: Keeping account logins and instructions only in memory, so an agent or family member has no usable record at the moment it is needed.
- Automatic contributions: Continuity matters more than optimization after 90. Common mistake: Assuming automatic payments will run forever without an agent in place, so that when the account holder cannot act, no one has authority to adjust the transfers as circumstances change.
- Simple portfolio: At this stage the portfolio's most valuable trait is continuity: someone else must be able to run it without the owner's help. Common mistake: Selling long-held appreciated holdings in a taxable account to simplify the portfolio, which realizes gains that the step-up in basis at death could have erased for heirs.
- Review once a year: The review for a ninety-something is a continuity audit. Common mistake: Relying on a will to direct accounts that carry their own beneficiary designations, which pass outside the will and may name a person who no longer matches the family's wishes.
- Avoid overtrading: After 90 the purpose of the portfolio is usually steady income and reliability, so the main risk of overtrading is paperwork and exploitation rather than market timing. Common mistake: Allowing an agent or new adviser to move holdings into complex or high-fee products with no second review, which can drain an account the owner may rely on for years.
