# Serious Investing for School Age (Ages 10-12)






- [Investment policy statement](https://www.getswoopr.com/investing-by-age/serious/school-age/policy-statement/): Between 10 and 12 the written policy is still owned by the adult, but it can begin to include the child as a reader. **Common mistake:** Leaving the education-savings allocation unchanged for years after the horizon has started to shorten, because the document was written once for a newborn and never reviewed.
- [Research sleeve](https://www.getswoopr.com/investing-by-age/serious/school-age/research-sleeve/): Between 10 and 12, a child can follow a company's story, but an adult still has to open the account and place every trade. **Common mistake:** Letting familiar brands, such as a favorite game or snack maker, stand in for research, so the written reasons describe products the child likes instead of what the business actually earns.
- [Concentration management](https://www.getswoopr.com/investing-by-age/serious/school-age/concentration/): At 10 to 12, a child usually has no earned income, so concentration shows up in what the custodian holds on the child's behalf and in what the child gets curious about. **Common mistake:** Letting one favorite company grow to dominate the custodial account because it feels like a lesson, when the same lesson could be taught with a small, clearly separate sleeve.
- [Tax location](https://www.getswoopr.com/investing-by-age/serious/school-age/tax-location/): At ages 10-12 the same two containers apply, but what sits where becomes more concrete. **Common mistake:** Holding bond funds or high-turnover funds in a child's taxable custodial account, where regular distributions are taxed at the parents' rate, without asking which assets generate the least taxable income there.
- [Rebalancing](https://www.getswoopr.com/investing-by-age/serious/school-age/rebalancing/): At 10 to 12 rebalancing is mostly an illustration. **Common mistake:** Treating a single year of drift in a small account as urgent and trading in it, when a new contribution could restore the targets without a sale or a taxable gain.
- [Scenario testing](https://www.getswoopr.com/investing-by-age/serious/school-age/scenario-testing/): With only several years until college, a 529's scenario test shifts from distant to dated. **Common mistake:** Assuming a decline can simply be waited out because the child is still young, when the withdrawal date is set by the first tuition bill rather than by market recovery.
- [Security research](https://www.getswoopr.com/investing-by-age/serious/school-age/security-research/): At ages 10-12 research can become a teaching exercise, because the account is still custodial and every decision is legally the adult's. **Common mistake:** Selling a position the first time its price falls, so the lesson the child absorbs is that price moves are the research, rather than the company's results and the reasons the position was chosen.
- [Exit rules](https://www.getswoopr.com/investing-by-age/serious/school-age/exit-rules/): Between 10 and 12, a child can follow a sell rule as a learning exercise, but an adult custodian still places and records each sale. **Common mistake:** Letting a child sell on a hunch or a headline because the account is small, which teaches reacting to news rather than testing whether the reason for owning has actually changed.
