About These ETFs
What Stands Out In This Comparison
What This Means
Both funds come from IShares. IJR is a small-cap U.S. equity ETF, while IWN is a U.S. value equity ETF. IJR and IWN overlap enough to matter, but they still bring different exposures to a portfolio. The overlap is concentrated in holdings such as CTRE, EPRT, and TRNO, which explains why the score lands at 43.76%.
How They Differ
Both funds come from IShares. IJR is a small-cap U.S. equity ETF, while IWN is a U.S. value equity ETF. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. IJR has the lower expense ratio, while IWN charges more for its exposure.
What Drives The Overlap
The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 3.26% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.
When One May Fit Better
Because IJR and IWN are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. IJR has the lower expense ratio, while IWN charges more for its exposure.
Overlap Driver Snapshot
Concentration
The top three shared holdings explain 3.26% 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
Both funds come from IShares. IJR is a small-cap U.S. equity ETF, while IWN is a U.S. value equity ETF. The overlap exists because both funds allocate meaningful weight to the same holdings. In this dataset, the biggest shared drivers are CTRE, EPRT, and TRNO, which appear in both portfolios and push the overlap score higher.
Holding both IJR and IWN can still be reasonable, but you should expect some duplication. The decision comes down to whether the non-overlapping parts of each ETF are important enough for your strategy.
