Wealthy PotEEM vs VWO: Two Very Different Ways to Own Emerging Markets
EEM and VWO both promise the same thing: one fund that owns the stock markets of the developing world, from Taiwan and China to India and Brazil. But they are built on different indexes, and two differences matter enough to decide the choice. One is the fee, where they are 12 times apart. The other is a single country, South Korea, that one fund holds heavily and the other excludes entirely. This guide uses figures pulled straight from iShares' and Vanguard's own fund documents.
The Short Answer
- Buying and holding emerging markets for the long run? VWO, almost always. It costs 0.06% against EEM's 0.72%, holds far more stocks including small caps, and gives you more China and India. If you specifically want South Korea in the mix, use IEMG (0.09%) instead, not EEM.
- A short-term trader who needs deep liquidity and a big options market? EEM is built for you. Its tight spreads and options chain are why it still holds ~$30 billion despite the high fee, but that is a trading tool, not a buy-and-hold vehicle.
For a long-term investor the practical contest is really VWO versus IEMG. EEM at 0.72% is hard to justify for anyone holding for years, and the rest of this guide explains why.
The Fee Gap Is the Headline
EEM charges an expense ratio of 0.72%. VWO charges 0.06%. That is a 12-fold difference, and on the same broad basket of emerging-market stocks it is the single biggest, most certain edge in this comparison. Fees are the one thing about a fund you know in advance; returns you don't.
Annual cost per $10,000 invested

That is $66 a year on every $10,000, before you count the compounding drag over decades. A high fee is not automatically wrong, but it has to buy you something. On a plain, broad emerging-markets index, it does not, and VWO proves the same exposure can be had for a twelfth of the price.
The Real Difference: South Korea
These two funds do not hold the same countries, and it comes down to how their index providers classify South Korea.
- EEM tracks the MSCI Emerging Markets Index, and MSCI still classifies South Korea as an emerging market. So EEM holds it, and heavily: Korea was about 23.7% of the fund, its second-largest country. That includes big positions in Samsung Electronics (~8.1%) and SK Hynix (~7.6%), two of the world's largest memory-chip makers.
- VWO tracks the FTSE Emerging Markets All Cap China A Inclusion Index, and FTSE classifies South Korea as a developed market. So VWO holds no Korea at all. In its place you get more China (about 25.6%, including mainland China A-shares) and more India (about 16.5%).
This is not a rounding difference. Nearly a quarter of EEM is Korean stocks that simply do not exist in VWO. If you have strong feelings about owning Samsung and the Korean chip complex, or about a heavier China and India weight, this decides it more than the fee does.

Note the concentration line. VWO holds far more stocks overall, yet its single top holding, Taiwan Semiconductor, is a slightly bigger slice of the fund than EEM's. VWO's top 10 is lighter (~27.7% vs ~40.2%) mainly because EEM stacks Korea's Samsung and SK Hynix near the top alongside TSMC.
Why EEM Beat VWO Recently
Over the past decade EEM returned about 9.58% a year against VWO's 8.49%, and over the past year the gap was dramatic: roughly 45% versus 24%. It is tempting to read that as EEM being the better fund. It isn't the fund, it's the country.
EEM's edge came almost entirely from South Korea, which VWO doesn't own. Samsung and SK Hynix are memory-chip makers, and memory prices surged during the AI hardware build-out. That single ~24% Korea slice, led by two semiconductor names, did the heavy lifting. It is a bet on Korean chips, not evidence that iShares runs a better emerging-markets fund. Pay the 0.72% fee and you are paying up for that specific tilt, when a decade of Korea underperformance is equally possible. Regions rotate; chasing the one that just won is the recency-bias trap covered in why time in the market beats timing it.
The Catch: IEMG Makes EEM Hard to Justify
Here is what most EEM-vs-VWO comparisons miss. If the reason you'd pick EEM is its Korea exposure and the MSCI index, iShares sells that same exposure far cheaper in a different fund: IEMG, the iShares Core MSCI Emerging Markets ETF, at an expense ratio of 0.09%.
IEMG tracks essentially the same MSCI emerging-markets universe as EEM, including South Korea, at a fraction of the cost, and it is now far larger than EEM by assets. That leaves EEM with one genuine reason to exist: it is a trading instrument. Its long history, huge daily volume, tight bid-ask spreads, and deep options market make it the tool institutions and short-term traders reach for. For a long-term holder, though, paying 0.72% when IEMG offers the same index at 0.09% and VWO offers the broad exposure at 0.06% is very hard to defend.
Which One Fits You
Choose VWO if: you are a long-term investor who wants the cheapest broad emerging-markets fund, is comfortable without South Korea, and likes the heavier China (including A-shares), India, and small-cap coverage. This is the default pick for most buy-and-hold portfolios.
Choose IEMG instead of EEM if: you specifically want the MSCI index with South Korea included, but for the long run. At 0.09% it gives you EEM's exposure without EEM's fee. For most people wanting Korea in their emerging-markets sleeve, this is the answer, not EEM.
Choose EEM only if: you are trading, not holding, and you need the deepest liquidity and options market in the category. That is a narrow, tactical use. And if you are still deciding whether to hold emerging markets at all, remember they are the developing-world slice of the international fund in VTI vs VXUS, which many investors own instead of buying a standalone EM fund.
FAQ
Is EEM or VWO better?
For long-term investors, VWO, in most cases. It costs 0.06% against EEM's 0.72%, holds more stocks, and covers small caps. EEM's main advantage is trading liquidity, which matters to traders, not buy-and-hold investors. If you want EEM's Korea exposure for the long run, IEMG (0.09%) is the cheaper way to get it.
Why does VWO not hold South Korea?
VWO's index provider, FTSE, classifies South Korea as a developed market, so it is excluded from FTSE's emerging-markets index. EEM's provider, MSCI, still classifies Korea as emerging, so EEM holds it (about 23.7% of the fund, including Samsung and SK Hynix).
Does VWO include China A-shares?
Yes. VWO tracks the FTSE Emerging Markets All Cap China A Inclusion Index, which holds mainland-listed China A-shares. That is part of why VWO's China weight (~25.6%) is higher than EEM's (~19.0%).
Why did EEM outperform VWO recently?
Mostly because of South Korea, which VWO doesn't own. Korean chipmakers Samsung and SK Hynix rallied hard during the AI-driven memory boom, and that ~24% Korea slice drove EEM's edge. It reflects a country bet, not a better-run fund, and past performance doesn't predict future results.
What is the difference between EEM and IEMG?
Both are iShares funds tracking MSCI emerging markets, including South Korea. IEMG (the "Core" fund) charges 0.09% and adds small caps; EEM charges 0.72% and is aimed at traders for its liquidity and options. For long-term holding, IEMG is the cheaper choice of the two.
