Why Kids' Investment Accounts Are Beating Adult Portfolios: A Guide to Junior-Depot Success
Imagine giving your child not just a financial head start, but an investment portfolio that outperforms your own. According to a major new study analyzing over 100,000 children's investment accounts (Junior-Depots), this is exactly what's happening. Parents who open investment accounts for kids are achieving higher average returns than in their own portfolios. This guide breaks down the key findings of the Junior-Depot study, revealing the simple, effective strategies—like ETF savings plans—that are driving this success and showing you how to apply them for your child's long-term financial future.
The Performance Gap: Junior-Depots Outpace Adult Accounts
The data is compelling. Between 2020 and 2024, the average children's investment account delivered a return of +19.6%. In contrast, the average adult portfolio returned +18.2% over the same period. The best-performing group was accounts for children aged 6-11, which gained 21.1%. This outperformance highlights a powerful lesson in investment strategy: a disciplined, long-term approach often beats the more reactive trading common in adult accounts.
The Winning Formula: Early Start + ETFs + Savings Plans
So, what's the secret sauce in these successful kids' portfolios? The study points to three key ingredients:
| Strategy Element | How It's Used in Junior-Depots | Impact on Performance |
|---|---|---|
| Early Start | 60-65% of accounts are opened for children aged 0-5. | Maximizes the power of compound interest over a time horizon of 18+ years. |
| ETF Dominance | ETFs make up over 60% of assets in accounts for kids under 11. | Provides low-cost, broad diversification, capturing global market growth. |
| Automated Savings Plans (Sparpläne) | Over 85% of accounts for 0-5 year-olds use a regular savings plan. | Enforces consistent, disciplined investing regardless of market conditions (dollar-cost averaging). |
This combination creates a "set-and-forget" system that avoids the common pitfalls of emotional trading and market timing that often hinder adult investors.
Portfolio Composition: Simplicity Wins
The asset allocation in children's accounts is strikingly simple and effective:
- ETFs & Funds: The core holding, representing 60-80% of assets depending on age.
- Individual Stocks: More common in teen accounts (up to ~30%). Popular picks include global tech leaders like Apple, Nvidia, and Microsoft, alongside German blue-chips like Allianz and Siemens.
- Notably Absent: Complex products like bonds, certificates, or derivatives play almost no role.
This focus on straightforward, growth-oriented assets is a major contributor to the strong performance.
The Power of Time and Mindset
The study identifies two non-financial factors that give Junior-Depots an edge:
- The Ultra-Long Time Horizon: With 18 years until adulthood, parents can truly invest for the long term, riding out market volatility without panic.
- The "Calmer Hand": When investing for their children, parents tend to be more systematic and less emotional. They set up a savings plan into a diversified ETF and let it run, avoiding the temptation to constantly buy and sell.
This contrasts with the shorter-term pressures and behavioral biases that frequently impact adult investment decisions.
Regional Disparities and Getting Started
The study also revealed a geographic divide, with higher participation in wealthier states like Bavaria and Hamburg. However, the strategy itself is accessible to everyone. The average monthly ETF savings plan contribution for a child's account is a manageable €67-€89.
Conclusion: Your Blueprint for a Child's Financial Future
The message from the data is clear: starting early with a simple, automated strategy in a Junior-Depot is one of the most powerful gifts you can give. By opening an investment account for your child and funding a regular ETF savings plan, you harness the unmatched power of compound growth over decades. You're not just saving money; you're teaching a lifelong lesson in wealth building and providing a substantial financial foundation for their adult life. The study proves that sometimes, the best investment strategy is also the simplest one.
