IEMG’s Outperformance Masks Concentration Risks in Tech and Asia

The iShares Core MSCI Emerging Markets ETF (IEMG) has returned 39% since May 2023, driven by outsized gains in its top holdings. TSM, Samsung, and SK Hynix—semiconductor giants—comprise over 20% of the fund’s assets and have surged on AI-related demand. These companies are the primary reason for IEMG’s recent outperformance. The ETF’s exposure is highly concentrated, with 78% of its holdings in Asia, and nearly all of that in Taiwan and China. This geographic and sectoral concentration amplifies its vulnerability to regional or industry-specific shocks. IEMG’s low 0.09% expense ratio and 2.42% yield remain competitive, but its long-term risk-adjusted returns remain behind those of developed market alternatives like VEA and SCHF.
