The Verdict
IEMG (Emerging Markets) and QQQM (US Large Cap Growth) sit in different corners of the market, so this is less a head-to-head than a question of what role each would play. They can be complements rather than alternatives — the metrics below show how differently the two have actually behaved.
On ETFValuer's overall model — which blends return, risk-adjusted performance, cost, drawdown, size and volatility — IEMG scores higher: 75.4 (Grade B+) versus 70.8 for QQQM. That doesn't make QQQM 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 0.15% for QQQM — a gap of 0.06 percentage points (about $6.00/year on a $10,000 position) that compounds meaningfully over a multi-decade holding period. Because these funds do different jobs, though, cost alone shouldn't decide it — a cheaper fund that gives you the wrong exposure is a false economy. See the ETF Fee Calculator for the exact dollar impact at your investment size and horizon.
What QQQM's Fees Cost You
QQQM charges an expense ratio of 0.15% 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.

Performance & Risk
Over the trailing 3 years, QQQM returned +81.69% versus +61.07% for IEMG — a gap of about 20.6 percentage points. On risk, IEMG has held up better historically, with a shallower max drawdown (-17.21% vs. -22.70%). IEMG currently has the better risk-adjusted return (Sharpe ratio of 0.96 vs. 0.90), meaning it delivered more return per unit of volatility taken on.
How Closely Do They Track Each Other?
Over the last 3.0 years of daily returns (752 shared trading days), IEMG and QQQM show a moderate correlation of 0.716 — related but meaningfully different. That's loose enough that the two funds do behave differently in a meaningful share of market conditions — holding both is defensible if you want exposure to each mandate.
| Measure | Value | What it means |
|---|---|---|
| Daily return correlation | 0.716 | Moderate — related but meaningfully different |
| R-squared | 51.3% | 51.3% of IEMG's daily moves are explained by QQQM's |
| Tracking error (annualised) | 14.82% | Typical yearly spread between the two funds' returns |
| Annualised return over 3.0y | IEMG +17.99% · QQQM +22.69% | QQQM ahead by 4.70 points a year |
Correlation alone understates how far these can drift. Across every rolling 12-month window in the period, IEMG finished as much as +29.2 points ahead of QQQM at the best extreme and -23.5 points at the worst — a 52.8-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
IEMG and QQQM share no companies among their top 10 reported holdings. That points to genuinely different exposure, so holding both is more likely to diversify than to duplicate. Full portfolios may still overlap further down the list.

Which One Should You Pick?
Lean IEMG if…
- You want the lower running cost — 0.09% vs 0.15%, about $6 a year less on a $10,000 position
- Current income matters to you — it yields 1.48% against 0.43%
Lean QQQM if…
- It has been the calmer ride (18.8% volatility vs 23.2%)
- You weight recent results heavily — it returned 81.7% over 3 years against 61.1%
These two are not really substitutes, so "both, in some proportion" is often the right answer rather than picking one. Model the blend with the Portfolio Blender.
