The Verdict
URA and XLB 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 — XLB scores higher: 53.7 (Grade C) versus 40.5 for URA. That doesn't make URA a bad fund; it means XLB 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
XLB is the cheaper fund, charging 0.08% a year versus 0.69% for URA — a gap of 0.61 percentage points (about $61.00/year on a $10,000 position) that compounds meaningfully over a multi-decade holding period. See the ETF Fee Calculator for the exact dollar impact at your investment size and horizon.

Performance & Risk
Over the trailing 3 years, URA returned +100.73% versus +26.70% for XLB — a gap of about 74.0 percentage points. On risk, XLB has held up better historically, with a shallower max drawdown (-23.17% vs. -37.81%). XLB currently has the better risk-adjusted return (Sharpe ratio of 0.46 vs. -0.07), 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), URA and XLB show a low correlation of 0.394 — largely independent of each other. These funds move largely on their own schedules. Combining them is a real diversification decision rather than a redundant one, which is the case where owning both can genuinely reduce portfolio volatility.
| Measure | Value | What it means |
|---|---|---|
| Daily return correlation | 0.394 | Low — largely independent of each other |
| R-squared | 15.6% | 15.6% of URA's daily moves are explained by XLB's |
| Tracking error (annualised) | 39.15% | Typical yearly spread between the two funds' returns |
| Annualised return over 3.0y | URA +26.99% · XLB +8.33% | URA ahead by 18.66 points a year |
Correlation alone understates how far these can drift. Across every rolling 12-month window in the period, URA finished as much as +136.3 points ahead of XLB at the best extreme and -18.3 points at the worst — a 154.6-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
URA and XLB 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 URA if…
- Current income matters to you — it yields 4.79% against 2.76%
- You weight recent results heavily — it returned 100.7% over 3 years against 26.7%
Lean XLB if…
- You want the lower running cost — 0.08% vs 0.69%, about $61 a year less on a $10,000 position
- It has been the calmer ride (17.7% volatility vs 51.8%) with a shallower worst-case fall (-23.2% vs -37.8%)
- You care about return per unit of risk — its Sharpe ratio of 0.46 beats -0.07
Whichever you pick, holding both at full weight is usually the wrong answer — see the overlap and correlation sections above.
