The Verdict
XLB and XME compete directly — both are Materials funds chasing the same job in a portfolio. That makes this a genuine either/or: the index each tracks, what it costs, and how it has handled drawdowns are what separate them, not the broad exposure they give you.
On ETFValuer's overall model — which blends return, risk-adjusted performance, cost, drawdown, size and volatility — XME scores higher: 60.5 (Grade C) versus 53.7 for XLB. That doesn't make XLB a bad fund; it means XME 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

Performance & Risk

On risk, XLB has held up better historically, with a shallower max drawdown (-23.17% vs. -30.47%). XME currently has the better risk-adjusted return (Sharpe ratio of 0.69 vs. 0.46), 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), XLB and XME show a moderate correlation of 0.688 — 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 | 0.688 | Moderate — related but meaningfully different |
| R-squared | 47.3% | 47.3% of XLB's daily moves are explained by XME's |
| Tracking error (annualised) | 22.53% | Typical yearly spread between the two funds' returns |
| Annualised return over 3.0y | XLB +8.33% · XME +24.93% | XME ahead by 16.60 points a year |
Correlation alone understates how far these can drift. Across every rolling 12-month window in the period, XLB finished as much as +7.8 points ahead of XME at the best extreme and -106.1 points at the worst — a 113.9-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
XLB and XME hold 2 of the same companies among their top 10 positions. Those shared names make up 9.7% of XLB and 8.9% of XME. That's modest duplication — the funds are mostly distinct at the top, so holding both can still add diversification.
| Shared Holding | XLB Weight | XME Weight |
|---|---|---|
| Freeport-McMoRan Inc | 5.26% | 4.36% |
| Nucor Corp | 4.39% | 4.50% |
Compares the top 10 reported holdings from each fund's most recent SEC N-PORT-P filing, so it understates total overlap — funds tracking similar indexes overlap far more deeply than the top 10 alone can show. Search any company across all tracked funds with the Stock Overlap tool.
Which One Should You Pick?
Lean XLB if…
- You want the lower running cost — 0.08% vs 0.35%, about $27 a year less on a $10,000 position
- Current income matters to you — it yields 2.76% against 0.31%
- It has been the calmer ride (17.7% volatility vs 36.5%) with a shallower worst-case fall (-23.2% vs -30.5%)
Lean XME if…
- You care about return per unit of risk — its Sharpe ratio of 0.69 beats 0.46
- You weight recent results heavily — it returned 92.1% over 3 years against 26.7%
Whichever you pick, holding both at full weight is usually the wrong answer — see the overlap and correlation sections above.
