The Verdict
IEMG (Emerging Markets) and XLK (Technology) 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 — XLK scores higher: 77.7 (Grade B+) versus 75.4 for IEMG. That doesn't make IEMG a bad fund; it means XLK currently edges it out on this specific mix of factors.

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
On cost, the two are essentially tied — IEMG charges 0.09% a year versus XLK's 0.08%. A difference this small (about $1.00 a year on a $10,000 position) isn't a reason to choose one fund over the other.
What IEMG's Fees Cost You
IEMG charges an expense ratio of 0.09% 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, XLK returned +101.18% versus +61.07% for IEMG — a gap of about 40.1 percentage points. On risk, IEMG has held up better historically, with a shallower max drawdown (-17.21% vs. -25.66%). XLK currently has the better risk-adjusted return (Sharpe ratio of 1.25 vs. 0.96), 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 XLK show a moderate correlation of 0.706 — 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 | 0.706 | Moderate — related but meaningfully different |
| R-squared | 49.9% | 49.9% of IEMG's daily moves are explained by XLK's |
| Tracking error (annualised) | 17.56% | Typical yearly spread between the two funds' returns |
| Annualised return over 3.0y | IEMG +17.99% · XLK +26.41% | XLK ahead by 8.42 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 +25.7 points ahead of XLK at the best extreme and -20.9 points at the worst — a 46.5-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 XLK 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…
- Current income matters to you — it yields 1.48% against 0.62%
Lean XLK if…
- You want the lower running cost — 0.08% vs 0.09%, about $1 a year less on a $10,000 position
- You care about return per unit of risk — its Sharpe ratio of 1.25 beats 0.96
- You weight recent results heavily — it returned 101.2% 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.
