The Verdict
EEM and IEMG are close to the same fund wearing different labels. Both sit in the Emerging Markets category and their daily returns move almost identically, so this is not really a question of which fund is better — it is a question of which one is cheaper to own and easier to trade in your account. Everything below is about finding the small, structural edges, because the investment exposure is a wash.
On ETFValuer's overall model — which blends return, risk-adjusted performance, cost, drawdown, size and volatility — IEMG scores higher: 77.6 (Grade B+) versus 70.4 for EEM. That doesn't make EEM a bad fund; it means IEMG currently edges it out on this specific mix of factors. Read the metric-by-metric breakdown below before deciding which matters more for your own portfolio.

Bold marks the better value in each row. "Better" is directional only (e.g. lower cost, higher return) — it isn't a recommendation by itself. See the full methodology.
Cost
IEMG is the cheaper fund, charging 0.09% a year versus 0.72% for EEM — a gap of 0.63 percentage points (about $63.00/year on a $10,000 position) that compounds meaningfully over a multi-decade holding period. Since these two deliver almost the same exposure, that fee gap is close to the entire difference between them — it comes straight out of your return with nothing offered in exchange. See the ETF Fee Calculator for the exact dollar impact at your investment size and horizon.
What EEM's Fees Cost You
EEM charges an expense ratio of 0.72% a year, deducted automatically from the fund's value. Small percentages compound into real money — adjust the figures below to see the impact on your own numbers.
Assumes a constant gross return and no additional contributions — a simplification, but it isolates exactly what the expense ratio costs. Try the full fee calculator to model contributions and compare any two funds.
Performance & Risk
Over the trailing 3 years, EEM returned +65.47% versus +64.19% for IEMG — a gap of about 1.3 percentage points. On risk, IEMG has held up better historically, with a shallower max drawdown (-17.21% vs. -17.29%). EEM currently has the better risk-adjusted return (Sharpe ratio of 1.18 vs. 1.13), meaning it delivered more return per unit of volatility taken on. Read that gap sceptically: for funds tracking near-identical exposure, a 1.3-point difference over three years is mostly noise from fee drag and timing, not evidence that one manager is better than the other.
How Closely Do They Track Each Other?
Over the last 3.0 years of daily returns (752 shared trading days), EEM and IEMG show a near-perfect correlation of 0.998 — functionally interchangeable. At this level the two funds are, for practical purposes, the same investment. Owning both adds no diversification whatsoever — the decision should come down entirely to cost, spread and which one your broker handles better.
| Measure | Value | What it means |
|---|---|---|
| Daily return correlation | 0.998 | Near-perfect — functionally interchangeable |
| R-squared | 99.6% | 99.6% of EEM's daily moves are explained by IEMG's |
| Tracking error (annualised) | 1.34% | Typical yearly spread between the two funds' returns |
| Annualised return over 3.0y | EEM +18.27% · IEMG +17.99% | EEM ahead by 0.27 points a year |
Correlation alone understates how far these can drift. Across every rolling 12-month window in the period, EEM finished as much as +3.5 points ahead of IEMG at the best extreme and -1.4 points at the worst — a 4.9-point spread between the best and worst year of relative performance. Two funds can correlate tightly day to day and still deliver very different outcomes over any single year you happen to hold them.
Calculated from daily total returns over the trailing 3-year window, recomputed every day this site refreshes. Correlation of 1.00 means the two funds moved in lockstep; 0.00 means their daily moves were unrelated.
Holdings Overlap
EEM and IEMG hold 10 of the same companies among their top 10 positions. Those shared names make up 33.8% of EEM and 31.8% of IEMG. That's heavy duplication — owning both largely doubles down on the same companies rather than spreading risk. Most investors should pick one.

Which One Should You Pick?
Lean EEM if…
- You weight recent results heavily — it returned 65.5% over 3 years against 64.2%
Lean IEMG if…
- You want the lower running cost — 0.09% vs 0.72%, about $63 a year less on a $10,000 position
- Current income matters to you — it yields 1.48% against 1.18%
- You want the deeper, more liquid market ($161B in assets vs $30B)
Whichever you pick, holding both at full weight is usually the wrong answer — see the overlap and correlation sections above.
