What is Asset Allocation? Asset Allocation is how a portfolio is divided among asset classes, typically stocks, bonds, cash, and sometimes real estate, chosen to balance expected return against the volatility an investor can tolerate. It is the single biggest driver of a portfolio’s long-term risk and return, more than which specific funds or stocks you pick within each class.
Worked example: a 30-year-old FIRE saver with a 30-year investing horizon might choose 90% stocks / 10% bonds, accepting larger short-term swings for higher expected growth. A 55-year-old five years from retirement might choose 60% stocks / 40% bonds, trading some growth for stability heading into the Safe Withdrawal Rate phase.
| Profile | Typical allocation |
|---|---|
| Early accumulation (20s-30s) | 90/10 to 100/0 stocks/bonds |
| Pre-retirement (5-10 yrs out) | 70/30 to 60/40 |
| Early retirement | Bond Tent or Glide Path applied |
A common mistake is picking an allocation based on maximizing historical returns alone, then abandoning it during the first real downturn. The right allocation is the most aggressive one an investor can hold through a 30-40% decline without selling. Once set, Rebalancing keeps the portfolio at its target weights as markets move it off course.
