What Stands Out In This Comparison

01

What This Means

RSP is an equal-weight U.S. equity ETF from Invesco, while XLB is an equity ETF from SPDR. RSP and XLB do not own much of the same portfolio weight. That usually means you are combining different parts of the market, with only a small amount of duplication through names like LYB, CF, and DOW.

02

How They Differ

RSP is an equal-weight U.S. equity ETF from Invesco, while XLB is an equity ETF from SPDR. RSP is the broader fund, while XLB is the more targeted sleeve. XLB has the lower expense ratio, while RSP charges more for its exposure.

03

What Drives The Overlap

The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 16.92% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.

04

When One May Fit Better

If you want the broader portfolio building block, RSP is usually the wider choice. If you want the more focused tilt, XLB is the narrower expression. XLB has the lower expense ratio, while RSP charges more for its exposure.

Overlap Driver Snapshot

Concentration

The top three shared holdings explain 16.92% of the full overlap score.

That helps show whether the score comes from a handful of giant shared positions or from a broader mix of common holdings.

Shared Sector Tilt

Sector tags are not consistently available for the biggest shared positions in this dataset, so this comparison leans more on the specific holdings than on sector labels.

Why These ETFs Overlap

RSP is an equal-weight U.S. equity ETF from Invesco, while XLB is an equity ETF from SPDR. The overlap exists because both funds allocate meaningful weight to the same holdings.

Holding both RSP and XLB can make sense if you want exposure to different sleeves of the market. The overlap is small enough that both funds may still improve diversification.
