# A Simple Diversified Portfolio Framework for Ages 40-49






## What Does a Simple Portfolio Look Like at Ages 40-49?



A simple diversified portfolio at Ages 40-49 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). 70-85% equity is a common target for this decade. Volatility has more consequence now because the accumulation runway is shorter. 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.



Bond allocation now matters. A 15-25% bond position provides meaningful protection against sequence-of-returns risk in the last decade before 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 40-49



Peak earnings can push income into the Roth IRA phase-out, $153,000 to $168,000 single or $242,000 to $252,000 married filing jointly, which limits direct contributions. Savings then often spill into a taxable account alongside the $24,500 workplace deferral, and there broad index funds with low turnover are easier to hold because gains after one year get long-term rates of 0%, 15% or 20%. College costs and aging parents compete for the same cash, so the mix itself rarely needs a change. The contribution plan does.



**A common mistake:** Selling a winner in a taxable account to rebalance before the one-year mark, which turns what would have been a long-term gain into a short-term one.








## 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.
