# Serious Investing for Young Children (Ages 1-9)






- [Investment policy statement](https://www.getswoopr.com/investing-by-age/serious/young-children/policy-statement/): At ages 1 to 9 the policy statement is written by a parent or custodian, and it governs only a small set of accounts, usually a 529 plan or a UGMA/UTMA custodial account. **Common mistake:** Writing the statement for a custodial account as if the money were the parent's, then discovering at the age of majority that the assets legally belong to the child and cannot be redirected.
- [Research sleeve](https://www.getswoopr.com/investing-by-age/serious/young-children/research-sleeve/): For ages 1 to 9, a research sleeve is a question about the account, not about stock selection. **Common mistake:** Buying a few individual stocks inside a custodial account as a gift or lesson, without realizing the shares belong to the child outright and can weigh on financial aid eligibility later.
- [Concentration management](https://www.getswoopr.com/investing-by-age/serious/young-children/concentration/): For a child under 10, concentration is mostly a custodial decision rather than a stock-picking one. **Common mistake:** Keeping a single gifted stock in a custodial account for years because it was a family present, so the child's first investable asset becomes a one-company position nobody would choose today.
- [Tax location](https://www.getswoopr.com/investing-by-age/serious/young-children/tax-location/): For ages 1-9 the location decision is mostly between a UGMA/UTMA account and a 529 plan, both run by an adult. **Common mistake:** Holding college savings in a custodial UTMA account by default, where the assets belong to the child and weigh more heavily in aid formulas, without comparing a 529 plan's tax treatment.
- [Rebalancing](https://www.getswoopr.com/investing-by-age/serious/young-children/rebalancing/): For ages 1 to 9 rebalancing is a custodian's task on a very small number of holdings, usually a 529 plan's age-based portfolio or a single fund in a custodial account. **Common mistake:** Selling winners in a custodial account on a schedule borrowed from adult portfolios, creating realized gains taxed to the child at the parents' rate under kiddie tax rules.
- [Scenario testing](https://www.getswoopr.com/investing-by-age/serious/young-children/scenario-testing/): For a parent or custodian of a child aged 1 to 9, scenario testing is mostly about the family's cash flow, not the child's account. **Common mistake:** Running only a market-crash scenario on a 529 plan and ignoring a stretch of tuition inflation, which can leave a plan underfunded even when portfolio returns look reasonable.
- [Security research](https://www.getswoopr.com/investing-by-age/serious/young-children/security-research/): At ages 1-9 the research is done entirely by a parent or custodian, and the question is as much about ownership as about the company. **Common mistake:** Buying a company because the child recognizes its toys, games or restaurants, then treating that familiarity as research without reading any filing or checking what the business actually earns.
- [Exit rules](https://www.getswoopr.com/investing-by-age/serious/young-children/exit-rules/): For ages 1 to 9, an exit rule is a custodian's rule, not a trading plan. **Common mistake:** Selling a custodial holding to cover a family expense unrelated to the child, which can misuse assets that legally belong to the child and cannot be treated as the custodian's personal funds.
