A simple diversified portfolio at Ages 70-79 has two or three components: a total US stock market index fund (or S&P 500 index fund), a total international stock market index fund, and a total bond market index fund (for investors who need a bond allocation). 40-55% equity is appropriate for most 70s investors who still have 15-25 years of potential longevity to plan for. Eliminating equities entirely is a longevity risk. The US/international split within the equity allocation is typically 60-70% US, 30-40% international, mirroring the global market-capitalization split. Target-date funds apply this split automatically. Intermediate-term bond funds and high-quality short-term bonds provide income and stability. TIPS (Treasury Inflation-Protected Securities) can help preserve purchasing power over a long retirement. The most important variable in the portfolio is the total equity-to-bond ratio. Research on long-term returns consistently shows that allocation is the primary driver of outcomes, not fund selection within each category. Choosing between two low-cost total market index funds is far less consequential than choosing the right equity-to-bond ratio. ## When Should You Rebalance? Rebalance when any asset class drifts more than 5 percentage points from its target. If your target equity allocation is 80% and the portfolio reaches 85% or 75%, that is the rebalancing trigger. Time-based rebalancing (quarterly or annual regardless of drift) produces similar outcomes to threshold-based rebalancing but requires more transactions. The 5% threshold rule typically triggers rebalancing once every 1-3 years in normal markets, which is appropriate for a casual investor with other demands on time. The tax implications of rebalancing depend on account type. In tax-advantaged accounts (401(k), IRA), selling overweight assets and buying underweight assets has no immediate tax consequence. In taxable brokerage accounts, selling a gain-generating asset triggers a capital gains tax. In taxable accounts, consider rebalancing primarily by directing new contributions to underweight asset classes rather than selling overweight ones. ## What Expense Ratios Are Acceptable for This Portfolio? Expense ratios below 0.10% are excellent and available from Vanguard, Fidelity, and Schwab for their total market index funds. Expense ratios between 0.10% and 0.20% are acceptable. Expense ratios above 0.50% are a meaningful performance drag over long periods and should be replaced with lower-cost equivalents when available. The difference between a 0.05% expense ratio and a 0.50% expense ratio on a 100,000 dollar portfolio over 30 years, assuming 7% annual growth, is approximately 120,000 dollars in additional wealth from the lower-cost fund. Fund expenses are a guaranteed cost subtracted from returns every year regardless of market performance. ## What Changes at Ages 70-79 Required minimum distributions turn the portfolio into a scheduled source of cash: age 73 for those born 1951 to 1959 and 75 for those born in 1960 or later. A divisor of 24.6 at 75 means the first year's withdrawal is a little over 4% of the prior year-end balance, so the bond or cash slice is naturally sized to cover it. Roth accounts have no owner RMDs, and a qualified charitable distribution from an IRA is allowed from age 70 and a half. **A common mistake:** Taking each year's required withdrawal by selling whichever fund is most convenient, which can quietly push the mix away from its target without anyone deciding to change it. ## Frequently Asked Questions ### How many funds does a diversified portfolio actually need? One to three. A single target-date fund provides complete diversification across domestic equities, international equities, and bonds with automatic rebalancing. A two-fund portfolio (total US market plus total international) covers the equity allocation and requires only periodic bond additions. A three-fund portfolio (US equity, international equity, bonds) provides explicit control over each allocation. More than three funds adds complexity without proportionally adding diversification for most retail investors. ### Should I include international equities? Yes for most investors. International stocks represent roughly 40% of global market capitalization. Excluding them concentrates the portfolio in the US market, which has dominated for the past 15 years but has underperformed international markets during other periods. A 20-30% international allocation provides genuine diversification across economic cycles. Target-date funds typically include international exposure automatically. ### Is this personalized financial advice? No. This content is educational.
