# Casual Investing for Launch Years (Ages 18-24)






- [One-fund portfolio](https://www.getswoopr.com/investing-by-age/casual/launch-years/one-fund/): The first job brings a 401(k) menu, and for many 18 to 24 year olds the plan's default is a single target-date fund, which makes one fund the path of least effort. **Common mistake:** Staying in a plan's default holding for years without checking what it is, especially when the default is a cash or stable value option intended only as a temporary placement.
- [30 minutes a year](https://www.getswoopr.com/investing-by-age/casual/launch-years/thirty-minutes/): At 18 to 24 jobs change often, so the monthly check is mostly about continuity: payroll deferral running, the match being captured, and the percentage not reset by a raise or a new employer. **Common mistake:** Changing jobs and leaving both the old plan's balance and the new plan's enrollment unattended, so contributions pause for months without any visible alarm.
- [Automatic contributions](https://www.getswoopr.com/investing-by-age/casual/launch-years/automatic-contributions/): The first job usually brings the first automatic mechanism: payroll deduction into a 401(k), 403(b) or similar plan with a $24,500 employee limit that most new earners will never approach. **Common mistake:** Accepting the plan's default deferral rate at hiring and never revisiting it, so the contribution stays at a starting level long after pay has grown.
- [Simple portfolio](https://www.getswoopr.com/investing-by-age/casual/launch-years/simple-portfolio/): Between 18 and 24 the first employer plan usually appears, and its menu often holds a target-date fund that is the entire simple portfolio in one line. **Common mistake:** Treating the old custodial account, the new 401(k) and a new IRA as three separate portfolios, each with its own mix, so the combined allocation ends up being nobody's deliberate choice.
- [Review once a year](https://www.getswoopr.com/investing-by-age/casual/launch-years/review-once/): For 18 to 24 year olds the annual review often follows a first job or a job change. **Common mistake:** Leaving the beneficiary field blank or at a default after the first enrollment, so an account could pass to an unintended person or through probate rather than to the person the owner would choose.
- [Avoid overtrading](https://www.getswoopr.com/investing-by-age/casual/launch-years/avoid-overtrading/): Between 18 and 24 the account is usually small, so one trade can move a large share of the whole portfolio. **Common mistake:** Opening a brokerage account with a first paycheck and trading daily on social media tips, which concentrates a small balance and creates short-term gains taxed as ordinary income.
