Building long-term financial stability is more than just investing — it requires structuring your money according to risk, goals, and liquidity needs. Many advisors recommend dividing investments into three layers:
- Safe fund: extremely liquid, covers urgent needs (accessible within days or 1–2 weeks)
- Medium fund: moderately liquid, accessible within 4–12 months, used for larger purchases or income protection
- Risky fund: long-term growth, higher volatility, less liquid
This article compares two strategies for a young investor with modest income, no major family obligations, and the comfort of parental support in emergencies. We simulate 20 years of investing, including a financial crisis and post-crisis recovery.
Initial Task and Assumptions
- Monthly salary: $2,000
- Investment: 5% of salary ($100/month)
- Fund returns:
- Safe fund: 3%/year
- Medium fund: 6%/year
- Risky fund: 14%/year
- Fund targets:
- Safe fund: 4 months of salary (~$8,000)
- Medium fund: 12 months of salary (~$24,000)
Strategies Compared
Strategy A – Balanced Allocation
Contributions split among Safe fund, Medium fund, and Risky fund. When a fund reaches its target, contributions shift to remaining funds.
Strategy B – All-In Risky
All contributions go to the Risky fund. The investor accepts high volatility early on, relying on parental support if emergencies arise.
Years 1–5: Early Growth
Table 1. Portfolio Values After 5 Years of Investment
| Fund | Strategy A | Strategy B |
|---|---|---|
| Safe fund | 2,155 | 0 |
| Medium fund | 2,325 | 0 |
| Risky fund | 2,868 | 8,605 |
| Total | 7,348 | 8,605 |
Strategy A grows steadily with some liquidity, while Strategy B grows faster but with no reserves.
Years 6–10: Crisis Period (3 Normal Years + 2 Crisis Years)
After the first five years of accumulation, the next five-year period is split into three normal growth years (Years 6–8) followed by a two-year financial crisis (Years 9–10).
During the crisis:
- Safe fund (Strategy A) experiences a positive adjustment (+2% crisis bonus) due to its low risk.
- Medium fund (Strategy A) suffers a 15% immediate drop, and returns are frozen at 0% during the crisis.
- Risky fund (Strategy A & B) suffers a 50% immediate drop, and returns are frozen at 0% during the crisis.
- Monthly contributions continue for all funds.
Table 2. Portfolio Values After 2-Year Crisis (End of Year 10)
| Fund | Strategy A | Strategy B |
|---|---|---|
| Safe fund | 4,831 | 0 |
| Medium fund | 4,276 | 0 |
| Risky fund | 3,717 | 11,155 |
| Total | 12,824 | 11,155 |
Years 11–15: Post-Crisis Recovery
During the post-crisis recovery phase:
- Safe fund (Strategy A) grows at 4.25% annual (3% base + 1.25% recovery bonus) until it reaches its $8,000 target. Once the target is reached, excess contributions and interest are redirected to Medium and Risky funds.
- Medium fund (Strategy A) grows at 8.5% annual (6% base + 2.5% recovery bonus) and receives redirected contributions from the Safe fund.
- Risky fund (Strategy A & B) grows at 18.5% annual (14% base + 4.5% recovery bonus). Strategy A receives redirected contributions from the Safe fund.
Table 3. Portfolio Values After 15 Years
| Fund | Strategy A | Strategy B |
|---|---|---|
| Safe fund | 8,000 | 0 |
| Medium fund | 10,747 | 0 |
| Risky fund | 16,234 | 37,683 |
| Total | 34,981 | 37,683 |
Years 16–20: Long-Term Growth
During this final five-year period:
- Safe fund remains at its $8,000 target. Contributions and interest beyond the target continue to flow to Medium and Risky funds.
- Medium fund (Strategy A) grows at 6% annual; receives its own contributions plus redirected contributions from Safe fund.
- Risky fund (Strategy A & B) grows at 14% annual; Strategy A receives contributions plus redirected contributions from Safe fund; Strategy B remains fully invested.

| Fund | Strategy A | Strategy B |
|---|---|---|
| Safe fund | 8,000 | 0 |
| Medium fund | 17,986 | 0 |

| Total | 62,400 | 83,232 |

| A – Total | 7,348 | 13,534 | 12,824 | 34,981 | 62,400 |
| B – Risky fund (only) | 8,605 | 17,511 | 11,155 | 37,683 | 83,232 |
| B – Total | 8,605 | 17,511 | 11,155 | 37,683 | 83,232 |
Criticism of Strategy B
- No liquidity buffer: Emergencies require selling risky assets at the worst market conditions.
- Crisis vulnerability: A 50% market drop can erase years of gains, as seen in Years 9–10.
- Psychological stress: Large drawdowns may lead to panic or poor decision-making.
- Timing risk: Withdrawals during downturns can be costly.
In crisis periods, the total portfolio value in Strategy B can fall below the remaining total in Strategy A. It means that strategy B fails. This highlights the importance of considering timing, liquidity, and crisis scenarios when investing aggressively. Further exploration is needed to see if such failures can be avoided and under what circumstances.
Advantages of Strategy B
- Maximum long-term growth: Achieves the highest total wealth ($83,232 after 20 years).
- Simple implementation: One fund to manage.
- Works for young investors with support: Particularly suitable for those without dependents and with parental assistance in emergencies.
Strategic Considerations
Strategy B is suitable for:
- Aggressive young investors with low financial obligations
- Investors who can rely on family support
- Long investment horizons (≥15 years)
Strategy A is suitable for:
- Investors needing an emergency fund and predictable liquidity
- Families or individuals with financial obligations
- Those seeking slower but stable growth with reduced volatility
Conclusion
This analysis invites further reflection. While Strategy B achieves the highest long-term wealth, it is vulnerable in crisis periods. The next steps will explore:
- Adding stress scenarios to both strategies
- Testing whether it is possible to avoid Strategy B failure during crises
- Making the simulated environment closer to real-life volatility
The aim of upcoming posts will be to model more realistic stress conditions and explore ways to strengthen both strategies under crisis situations.
