Week 26 Day 6: The Five-Fund Portfolio: Putting It Together

A sample allocation for a 45-year-old investor: VTI: 40% (core U.S. stock growth). SCHD: 20% (dividend income + quality factor). SCHH: 10% (real estate diversification). VCIT: 20% (corporate bond income). VTIP: 10% (inflation protection). Total expense ratio: approximately 0.04%. Total yield: approximately 2.5-3.0%. Total expected long-term return: approximately 7-8%. This portfolio covers U.S. stocks, real estate, corporate bonds, and inflation-protected bonds in five low-cost funds.

The five-fund portfolio customized by stage of life: Aggressive (20s-30s): VTI 50%, SCHD 25%, SCHH 10%, VCIT 10%, VTIP 5%. High stock allocation for maximum growth. Income comes from reinvested dividends compounding over decades. Moderate (40s-50s): VTI 35%, SCHD 25%, SCHH 10%, VCIT 20%, VTIP 10%. Balanced between growth and income. The bond allocation (30%) provides stability and cash flow. Conservative (60s+): VTI 20%, SCHD 25%, SCHH 10%, VCIT 30%, VTIP 15%. Income-focused. The 45% bond allocation reduces volatility. SCHD's growing dividends partially offset inflation. Rebalancing: once per year, sell overperformers and buy underperformers to maintain your target allocation. This forces 'buy low, sell high' behavior systematically. Tax efficiency: hold VCIT and VTIP in tax-advantaged accounts (401k, IRA) because bond interest is taxed as ordinary income. Hold VTI and SCHD in taxable accounts where dividends qualify for the lower 15-20% tax rate.

This five-fund model represents a multi-factor, multi-asset class portfolio that captures several documented risk premia: (1) the equity risk premium via VTI, (2) the value and quality factor premia via SCHD, (3) the real estate factor premium via SCHH, (4) the credit risk premium via VCIT, and (5) the inflation risk premium via VTIP. The correlation structure of these five assets provides meaningful diversification: VTI-VCIT correlation approximately 0.2-0.3, VTI-VTIP correlation approximately 0.1-0.2, SCHD-SCHH correlation approximately 0.5-0.6. The portfolio's expected Sharpe ratio (risk-adjusted return) is higher than any single component because of these imperfect correlations. Using historical return data (2011-2024), mean-variance optimization with realistic constraints suggests an allocation close to the moderate portfolio described above (35-40% VTI, 20-25% SCHD, 5-10% SCHH, 20-25% VCIT, 5-10% VTIP) for an investor targeting the maximum Sharpe ratio. For retirement-stage investors, the 'liability-driven investing' framework (Leibowitz, 2011) would increase the VTIP and VCIT allocations to match the inflation-adjusted and nominal cash flow needs, respectively. One improvement for advanced investors: add international exposure (VXUS at 15-20%) to reduce home-country concentration. The current five-fund portfolio is entirely U.S.-based, which introduces geographic concentration risk. However, for simplicity, the five-fund U.S. portfolio captures the majority of the available diversification benefit.
