3.1 Stock Ratio by Age
A practical rule of thumb is "110 - age" for stock allocation. For example, at 30 years old, a 70% to 80% stock mix can be reasonable depending on risk tolerance.
| Age | Stocks | Bonds | Risk |
|---|---|---|---|
| 20s | 80% | 20% | Aggressive |
| 30s | 70% | 30% | Active |
| 40s | 60% | 40% | Balanced |
| 50s | 50% | 50% | Stable |
3.2 Annual Rebalancing
When market changes alter your ratios, rebalancing restores the original allocation. Check your portfolio every January or on your birthday.

Dollar-cost averaging (DCA) helps you stay consistent through volatility. You buy more shares when prices are lower and fewer when prices are higher, reducing timing risk.
