What Stands Out In This Comparison

01

What This Means

IWR is a mid-cap U.S. equity ETF from IShares, while XLE is an energy sector ETF from SPDR. IWR and XLE 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 VLO, PSX, and MPC.

02

How They Differ

IWR is a mid-cap U.S. equity ETF from IShares, while XLE is an energy sector ETF from SPDR. IWR is the broader fund, while XLE is the more targeted sleeve. XLE has the lower expense ratio, while IWR 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 29.13% 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, IWR is usually the wider choice. If you want the more focused tilt, XLE is the narrower expression. XLE has the lower expense ratio, while IWR charges more for its exposure.

Overlap Driver Snapshot

Concentration

The top three shared holdings explain 29.13% 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

IWR is a mid-cap U.S. equity ETF from IShares, while XLE is an energy sector ETF from SPDR. The overlap exists because both funds allocate meaningful weight to the same holdings.
