Asset Allocation
Asset allocation is the process of dividing your investment portfolio among different asset categories — most commonly stocks, bonds, and cash equivalents — to balance potential returns against risk based on your financial goals, time horizon, and risk tolerance.
The Core Asset Classes
| Asset Class | Typical Risk | Typical Return | Role in Portfolio | |-------------|-------------|----------------|-------------------| | Stocks (equities) | High | High | Growth | | Bonds (fixed income) | Medium | Medium | Stability, income | | Real estate | Medium-High | Medium-High | Diversification, income | | Cash & equivalents | Low | Low | Liquidity, safety |
Why Asset Allocation Matters
Studies suggest that asset allocation — not individual stock selection or market timing — accounts for the majority of long-term portfolio returns variation. Getting the right mix for your situation is more important than picking the right individual investments.
Common Allocation Rules of Thumb
- Rule of 110: Subtract your age from 110 to get your stock percentage (e.g., age 30 → 80% stocks, 20% bonds). A modern update uses 120 given longer lifespans.
- Target Date Funds: Automatically shift from aggressive (more stocks) to conservative (more bonds) as you approach retirement.
Time Horizon and Risk Tolerance
- Long time horizon (20+ years): Can tolerate more volatility; typically higher stock allocation
- Short time horizon (under 5 years): Prioritize preservation; typically higher bond/cash allocation
- High risk tolerance: Comfortable with large swings for higher potential growth
- Low risk tolerance: Prefer stability even at the cost of lower long-term returns
