SCHF, a Schwab-managed developed-market ETF, sits in the same category as VEA and IEFA, but at a 0.03% expense ratio it's the cheapest international ETF in this batch. Its top holdings — Samsung Electronics, ASML, SK hynix — are also semiconductor-heavy.

Its 25.2% one-year return has been nearly identical to VEA's 25.1%. If cost is the top priority, SCHF is the most advantageous developed-market pick in this batch.
