Understanding Asset Allocation for Retirees
Asset allocation is the process of dividing investments among different asset classes—stocks, bonds, cash, and alternatives—to balance risk and reward. For retirees, the primary goals shift from accumulation to preservation and income generation.
Key Considerations for a 70-Year-Old Couple
- Risk Tolerance – At 70, the ability to recover from market downturns diminishes. A more conservative approach often makes sense.
- Income Needs – Social Security, pensions, and required minimum distributions (RMDs) play a role in cash flow planning.
- Longevity Risk – With life expectancies rising, portfolios must last 20-30 years or more.
- Inflation Protection – Fixed-income investments may not keep pace with rising costs.
- Tax Efficiency – Asset location (placing tax-efficient investments in taxable accounts) matters.
The Traditional Approach: The 60/40 Portfolio
A classic retirement allocation is 60% stocks and 40% bonds. But is this still optimal?
Pros of a 60/40 Allocation
- Balanced Growth & Stability – Stocks provide growth; bonds reduce volatility.
- Historical Performance – Over long periods, this mix has delivered ~7-8% annual returns.
Cons of a 60/40 Allocation
- Interest Rate Sensitivity – Bonds lose value when rates rise.
- Inflation Risk – Fixed-income returns may lag inflation.
Example Calculation
Assume a $1M portfolio with a 60/40 split:
- Stocks (60%) = $600,000
- Bonds (40%) = $400,000
If stocks return 6% and bonds 3%, the expected annual growth is:
Expected\ Return = (0.60 \times 0.06) + (0.40 \times 0.03) = 0.048\ or\ 4.8\%This may not be enough if withdrawals exceed 4%.
Modern Adjustments: The Case for Alternatives
Given today’s low-yield environment, some retirees incorporate alternatives:
| Asset Class | Allocation (%) | Purpose |
|---|---|---|
| US Stocks | 35 | Growth |
| Int’l Stocks | 15 | Diversification |
| Bonds | 30 | Stability |
| REITs | 10 | Inflation hedge |
| Cash | 10 | Liquidity |
Why REITs?
Real Estate Investment Trusts (REITs) provide income and inflation protection. Historically, they’ve yielded 4-6%.
Why International Stocks?
Diversification reduces reliance on US markets. Emerging markets offer growth potential.
The Role of Annuities in Retirement
Annuities can provide guaranteed income, reducing sequence-of-returns risk.
Immediate vs. Deferred Annuities
- Immediate Annuity – Starts payments right away.
- Deferred Annuity – Begins payments later, often at a higher rate.
Example: A $200,000 Immediate Annuity
At age 70, a joint-life annuity might pay ~$900/month. This supplements Social Security and reduces portfolio withdrawals.
Tax-Efficient Withdrawal Strategies
Withdrawals should follow a tax-smart sequence:
- RMDs First – Required after age 73 (SECURE 2.0 Act).
- Taxable Accounts Next – Capital gains rates are often lower than ordinary income.
- Tax-Deferred Accounts (IRA/401k) – Withdrawals are taxed as income.
- Roth Accounts Last – Tax-free growth.
Example: Minimizing Tax Drag
Suppose a couple has:
- $300k in taxable accounts
- $500k in a Traditional IRA
- $200k in a Roth IRA
They should take RMDs first, then sell taxable assets with long-term gains (taxed at 0-15%), and delay Roth withdrawals.
Dynamic Asset Allocation: Adjusting Over Time
A static 60/40 split may not work forever. A glidepath strategy adjusts allocations as needs change.
Suggested Glidepath for a 70-Year-Old Couple
| Age Range | Stocks (%) | Bonds (%) | Cash (%) |
|---|---|---|---|
| 70-75 | 50 | 40 | 10 |
| 75-80 | 45 | 45 | 10 |
| 80+ | 40 | 50 | 10 |
This gradual shift reduces equity exposure as longevity risk declines.
Monte Carlo Simulations: Stress-Testing the Portfolio
Financial planners use Monte Carlo simulations to test withdrawal sustainability.
Example Simulation Inputs
- Portfolio: $1M
- Allocation: 50% stocks, 40% bonds, 10% cash
- Withdrawal Rate: 4% ($40,000/year)
- Time Horizon: 25 years
The simulation runs 10,000 market scenarios to estimate success probability.
Behavioral Risks: Staying Disciplined
Retirees often make emotional decisions—selling in downturns or chasing high returns. A written investment policy statement (IPS) helps maintain discipline.
Common Behavioral Mistakes
- Market Timing – Trying to “buy low, sell high” often backfires.
- Overreacting to News – Short-term volatility shouldn’t derail long-term plans.
Final Recommendations
- Start Conservative – A 50/50 or 40/60 stock/bond split may suit most 70-year-olds.
- Diversify Beyond Stocks & Bonds – Consider REITs, TIPS, or dividend-paying stocks.
- Use Annuities for Guaranteed Income – Covers essential expenses.
- Optimize Withdrawals for Taxes – Minimize unnecessary tax drag.
- Review Annually – Adjust for health changes, market conditions, and spending needs.
Sample Portfolio for a 70-Year-Old Couple
| Asset Class | Allocation (%) | Example ETFs |
|---|---|---|
| US Large-Cap Stocks | 30 | VTI |
| International Stocks | 15 | VXUS |
| Bonds | 35 | BND |
| TIPS | 10 | SCHP |
| Cash | 10 | Money Market |
Conclusion
Asset allocation at 70 isn’t about maximizing returns—it’s about balancing safety, income, and growth. By diversifying wisely, managing taxes, and staying disciplined, a retired couple can enjoy financial peace of mind.
