What Stands Out In This Comparison

01

What This Means

Both funds come from SPDR. XLB is an equity ETF, while XLI is an industrials ETF. XLB and XLI 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 very few shared positions.

02

How They Differ

Both funds come from SPDR. XLB is an equity ETF, while XLI is an industrials ETF. XLB is the broader fund, while XLI is the more targeted sleeve. XLB and XLI are priced very similarly on expense ratio.

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 0% 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, XLB is usually the wider choice. If you want the more focused tilt, XLI is the narrower expression. XLB and XLI are priced very similarly on expense ratio.

Overlap Driver Snapshot

Concentration

The top three shared holdings explain 0% 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.

Top Shared Holdings

These are the holdings contributing the most to the overlap score between XLB and XLI.

These ETFs do not share any holdings in the current dataset.

Why These ETFs Overlap

Both funds come from SPDR. XLB is an equity ETF, while XLI is an industrials ETF. The overlap exists because both funds allocate meaningful weight to the same holdings. In this dataset, the biggest shared drivers are very few shared positions, which appear in both portfolios and push the overlap score higher.

Holding both XLB and XLI 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.
