The key composition differences: EEM is heavy semiconductor (TSMC + Samsung + SK Hynix = ~21 percent), heavy China (~25 percent), heavy emerging Asia (~80 percent including Taiwan, Korea, India). EFA is heavy Japan (~22 percent), heavy European (~50 percent including UK, France, Germany, Switzerland, Netherlands), heavy quality healthcare (~14 percent through Novo, Roche, AstraZeneca).
The 2025-2026 EEM-vs-EFA Outperformance
EEM has gained 53 percent over trailing 12 months while EFA gained 21.82 percent (31.2 percentage point EEM outperformance). The EM dominance has been driven by AI hardware semiconductor demand concentrated in TSMC, Samsung, and SK Hynix.
The TSMC alone factor: TSMC manufactures chips for Nvidia, Apple, Qualcomm, AMD AI accelerators. TSMC stock gained 80 percent in 2024-2025. With TSMC at 13.26 percent of EEM, that gain alone added approximately 11 percentage points to EEM returns. EFA has no equivalent single-stock contribution; the largest EFA holding (Novo Nordisk at ~5 percent) gained approximately 30 percent over 12 months, contributing about 1.5 percentage points.
Additional EEM drivers: Samsung Electronics +50 percent on HBM memory demand, SK Hynix +60 percent same driver. China stimulus (Tencent +30 percent, Alibaba +50 percent on regulatory clarity). India growth (Sensex new highs). Combined, EM has captured the AI hardware cycle plus China policy stimulus plus India growth.
Currency and Dollar Sensitivity
Both EEM and EFA are unhedged to USD. Currency contributions to returns differ materially.

Why has EEM outperformed EFA in 2025-2026?+
EEM gained 53% trailing 12 months vs EFA 21.82% (31.2pp EM outperformance). Driven by AI hardware semiconductor demand concentrated in TSMC, Samsung, SK Hynix. TSMC alone factor: manufactures chips for Nvidia, Apple, Qualcomm, AMD. TSMC +80% 2024-2025. With TSMC at 13.26% of EEM, that gain alone added ~11pp to EEM returns. EFA has no equivalent single-stock contribution: largest holding Novo Nordisk ~5% gained ~30% over 12 months contributing ~1.5pp. Additional EEM drivers: Samsung +50% (HBM memory), SK Hynix +60%, Tencent +30%, Alibaba +50% on regulatory clarity, India Sensex new highs.
How does currency affect EEM vs EFA?+
Both unhedged to USD. EEM currency exposure: ~35-45% of volatility from currencies (CNY, TWD, KRW, INR, BRL, MXN, ZAR). EM currencies more volatile than developed. EFA currency exposure: ~30-40% of volatility from currencies (EUR, JPY, GBP, AUD, CHF).
