iShares Core MSCI Emerging Markets ETF (IEMG +2.80%) provides targeted exposure to developing economies with a significant technology tilt, whereas the Vanguard Total International Stock ETF (VXUS +1.58%) offers broad-based, low-cost diversification across both developed and emerging international markets.
These funds represent two distinct approaches to international investing. One serves as a comprehensive solution for non-U.S. equity exposure, while the other focuses on the high-growth, higher-volatility potential of emerging nations. This comparison explores which strategy may best suit an investor’s specific geographic preferences and risk tolerance.

Which fund is the better buy?
These are both sizable funds with relatively low expenses, although Vanguard’s is notably lower than iShares’.
One major difference lies in their geographic focus. The Vanguard Total International Stock ETF — VXUS — is 82% in developed-world stocks, with the balance primarily in emerging markets. Its top country-level holdings are Japan (15.2%), Taiwan (8.6%), and Canada (7.8%).
IEMG, by comparison, is 52% developed markets outside the U.S., 1% in the U.S., and 47% in emerging markets. The iShares Core MSCI Emerging Markets ETF is actually more heavily invested in large-cap stocks despite its greater weighting in emerging markets, at 83% large caps compared to 80% for VXUS.
For investors, probably the primary differentiator is performance. Here, IEMG has performed well over the past three years, outperforming VXUS in the 3-year lookback, with a total annualized return of 22.6% versus 18.7%. The Vanguard fund wins the 5-year time frame, with an 8.8% annualized return compared to IEMG’s 7.5%. The iShares fund, however, bests Vanguard in the 10-year lookback, at 10.1% to 10%.
Strong performance makes the iShares Core MSCI Emerging Markets ETF have a slight edge over the Vanguard Total International Stock Market ETF.
