Performance Comparison: What the Data Reveals

While past performance doesn’t guarantee future results, analyzing historical returns provides valuable context:

• Over 10 years, VTIAX outperformed SWISX by 1.2% annually on average (primarily during emerging markets rallies)

Important note: VTIAX’s emerging markets exposure creates performance divergence – it outperforms when EM leads but lags during EM downturns.

Final Verdict

SWISX shines for cost-conscious investors focused exclusively on developed markets, while VTIAX delivers superior diversification for those seeking complete international exposure. For most long-term investors, VTIAX’s broader market coverage justifies its slightly higher fee – but SWISX remains compelling for Schwab users prioritizing ultra-low expenses. Evaluate your existing allocations, risk tolerance, and account structure to determine which international workhorse best gallops toward your financial finish line.
