3 ETFs to Build a Diversified, Low-Cost Investment Portfolio

Build a diversified investment portfolio with three ETFs: US total market, international equities, and core bonds. Low-cost, simple asset allocation strategy.

Sometimes the simplest solution is also a superior one. For many investors, three well-chosen ETFs can form the backbone of a diversified portfolio that’s low-cost, easy to manage, and aligned with long-term goals.

Start with a broad US equity ETF to capture the domestic stock market. A total market or S&P 500 ETF gives exposure to hundreds or thousands of companies across industries, providing instant diversification and market-driven growth potential. Look for index ETFs with low expense ratios to keep costs down.

Add an international equity ETF to broaden geographic exposure. International ETFs (including developed and emerging markets) reduce home-country concentration risk and tap into growth opportunities outside the U.S. Combining domestic and international index ETFs helps create a global equity sleeve that balances opportunity and risk.

Complete the core with a bond ETF for income and stability. A total bond market ETF or core aggregate bond ETF provides exposure to government and investment-grade corporate bonds, which can dampen portfolio volatility and produce reliable income. Bonds are especially important for investors seeking lower-risk allocations or planning for shorter-term needs.

How to combine them: asset allocation depends on your risk tolerance and time horizon. A common rule might be 60/40 (60% equities, 40% bonds) split between domestic and international equities (for example, 70% US / 30% international within the equity portion). Conservative investors may prefer 40/60, while aggressive investors might choose 80/20. Rebalance annually or semiannually to maintain target allocations.

Benefits of this three-ETF approach include simplicity, transparency, and low cost. Index ETFs offer tax efficiency and broad market exposure without the need to pick individual stocks. Using just three funds reduces complexity while still delivering diversification across asset classes and regions.

Examples of popular ETFs include total market ETFs (like VTI), international ETFs (like VXUS), and core bond ETFs (like BND or AGG), but always verify fund details and expense ratios.
