Where VBR and XLB differ
Sector weights as a share of each fund, ordered by the size of the gap rather than the size of the sector — two funds that overlap heavily still usually diverge somewhere.
| Sector | VBR | XLB | Δ |

| Materials | 7.2% | 99.8% | −92.6pp |
| Industrials | 18.8% | 0.0% | +18.8pp |

Δ is VBR minus XLB, in percentage points. Sector data is not published by every issuer, so “Unclassified” is a real category rather than a gap in the table.
