IEMG vs. VWO – Differences in Methodology and Composition
If you've landed here, you probably already know that index funds are a great way to get instant diversification across sectors and cap sizes. Competition for lower fees has also made index ETFs cheaper for retail investors with every passing year.
IEMG is the iShares Core MSCI Emerging Markets ETF. It is the second most popular fund to capture Emerging Markets stocks, so it made the list when I explored the best Emerging Markets ETFs here. It was established in late 2012. The fund seeks to track the MSCI Emerging Markets Investable Market Index. IEMG has over $75 billion in assets and has a little over 2,500 holdings.
VWO is the Vanguard FTSE Emerging Markets ETF. The fund provides similar broad exposure to Emerging Markets stocks. It launched in 2005. The fund seeks to track the FTSE Emerging Markets All Cap China A Inclusion Index. This ETF holds about 4,300 stocks. VWO is slightly more popular than IEMG with over $80 billion in assets.
The biggest difference here is that IEMG includes South Korea while VWO does not. A big name in the crosshairs that comes to mind is Samsung. As a result, VWO is more concentrated geographically with greater exposure to its top markets like China, India, and Taiwan, which comprise roughly 67% of the fund, while these countries make up about 59% of IEMG.
This is the case because the MSCI index that IEMG tracks classifies Korea as an emerging market, while VWO's FTSE index does not. Thus, you'll instead find Korea in VEA, Vanguard's ETF for Developed Markets.
As you'll see below, all this hasn't resulted in a significant performance difference between the two.
Both of these funds are highly liquid, with an average spread of 0.01%. Sector composition is nearly identical, with IEMG having slightly more exposure to tech companies. IEMG also costs 1 basis point more with a fee of 0.09%, while VWO is 0.08%.
IEMG vs. VWO – Historical Performance
Outperformance between these two tends to switch off year to year. Going back to IEMG's inception in 2012, it has slightly outperformed VWO when looking through 2021:
Conclusion – IEMG vs. VWO
IEMG and VWO are basically interchangeable, but your choice may come down to your view on Korea and subsequently, whether or not your portfolio is also exposed to ex-US Developed Markets. I already have Korea via VEA, so I like VWO just for its slightly lower fee and greater number of holdings, so I own it. Either is a fine choice for broad exposure to Emerging Markets. This is definitely a great pair to use for tax loss harvesting purposes to avoid a wash sale.
