6 Critical Mistakes to Avoid in Two-Fund Investing

1. Overlapping Holdings
Many investors unknowingly choose funds with significant overlap, reducing diversification benefits. Always check underlying holdings before combining funds.

2. Ignoring Expense Ratios
High fees can erode returns over time. Prioritize low-cost index funds and ETFs to maximize long-term wealth accumulation.

3. Emotional Rebalancing
Stick to your predetermined rebalancing schedule (quarterly or annually) rather than making emotional adjustments based on market volatility.

4. Neglecting Tax Efficiency
Use tax-advantaged accounts strategically and consider tax-managed funds to minimize the impact of taxes on investment returns.

5. Inadequate Emergency Fund
Ensure 3-6 months of expenses in high-yield savings before implementing any two-fund portfolio strategy for optimal financial security.

6. Lack of Regular Review
Review your portfolio allocation annually and adjust based on changing life circumstances, risk tolerance, and investment goals.
