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 IWD is a U.S. value equity ETF. IJR and IWD 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 SOLS, EMN, and LKQ.
How They Differ
Both funds come from IShares. IJR is a small-cap U.S. equity ETF, while IWD 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 IWD 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 13.58% 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 IWD are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. IJR has the lower expense ratio, while IWD charges more for its exposure.
Overlap Driver Snapshot
Concentration
The top three shared holdings explain 13.58% 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 IWD 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 SOLS, EMN, and LKQ, which appear in both portfolios and push the overlap score higher.
Holding both IJR and IWD 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.
