What Stands Out In This Comparison

01

What This Means

IWP is a U.S. growth equity ETF from IShares, while XLK is a technology-focused equity ETF from SPDR. IWP and XLK 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 MPWR, DDOG, and FICO.

02

How They Differ

IWP is a U.S. growth equity ETF from IShares, while XLK is a technology-focused equity ETF from SPDR. IWP is the broader fund, while XLK is the more targeted sleeve. XLK has the lower expense ratio, while IWP 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 51.44% 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, IWP is usually the wider choice. If you want the more focused tilt, XLK is the narrower expression. XLK has the lower expense ratio, while IWP charges more for its exposure.

Overlap Driver Snapshot

Concentration

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.
