iShares Core MSCI Emerging Markets ETF is significantly more concentrated in the technology sector, with nearly 44% of its portfolio in that space compared to 31% for the Vanguard fund
The Vanguard Total World Stock ETF (NYSEMKT:VT) provides exposure to global equities including the United States, while the iShares Core MSCI Emerging Markets ETF (NYSEMKT:IEMG) targets exclusively developing economies.
Investors seeking a single-fund solution for global stock exposure often weigh these two instruments. While both cover international markets, the Vanguard fund includes a massive allocation to domestic U.S. giants.

Which fund is the better buy?
These are both sizable funds with relatively low expenses.
If you’re looking for a one-stop-shop ETF for your portfolio, then VT, the Vanguard Total World Stock ETF, is the choice. This fund covers the world, as it names suggets, including exposure to the U.S. stock markets. Given that the U.S. is the world’s largest equity market, VT allocates 62% of its portfolio to U.S. stocks. Japan, at 6%, and Taiwan, at about 3.5%, are the next largest countries. Nearly 32% of its portfolio is in developed-world markets outside the U.S., with the balance in emerging markets.
IEMG, the iShares Emerging Markets ETF, by comparison, is 51% developed markets outside the U.S., 1% in the U.S., and 49% in emerging markets. Taiwan is the largest country represented, at 28% of the portfolio, followed by South Korea at 19%, and China at just under 19%. IEMG is actually more heavily invested in large-cap stocks despite its greater weighting in emerging markets, at 82% large caps compared to 75% for VT. That implies IEMG owns the dominant businesses in the emerging markets.
Performance-wise, each fund can claim to be better than the other, depending on what time frame you look at. IEMG has been excelling recently, up 24.4% (to 12% for VT) year-to-date and 42.2% in the past 52 weeks, compared to 24.3% for VT. IEMG is three percentage points better than VT over the 3-year time frame, with 22.6% annualized returns, while VT is better over the 5-year and 10-year look-backs, with 10.9% and 12.8% returns, respectively, compared to IEMG’s respective 7.5% and 10.1% gains.
That makes choosing between IEMG and VT a difficult one. Odds are a U.S. investor already has lots of exposure to domestic equities elsewhere in their portfolio, which means VT would be overweighting American stocks more than one may intend. Go with IEMG to get the rest of the world well represented in your portfolio.
