Compare another pair
Both funds come from IShares. QUAL is an equity ETF, while SCZ is a small-cap U.S. equity ETF. QUAL and SCZ 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 066922519 and 066922477.
Both funds come from IShares. QUAL is an equity ETF, while SCZ is a small-cap U.S. equity ETF. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. QUAL has the lower expense ratio, while SCZ charges more for its exposure.
The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 100.56% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.
Because QUAL and SCZ are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. QUAL has the lower expense ratio, while SCZ charges more for its exposure.
Concentration
The top three shared holdings explain 100.56% 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.
These are the holdings contributing the most to the overlap score between QUAL and SCZ.
| Holding | Name | QUAL Wt. | SCZ Wt. | Overlap |
|---|---|---|---|---|
| 066922519 | BlackRock Funds III: BlackRock Cash Funds: Institutional; SL Agency Shares | 0.38% | 3.82% | 0.38% |
| 066922477 | BlackRock Funds III: BlackRock Cash Funds: Treasury; SL Agency Shares | 0.13% | 0.03% | 0.03% |
Both funds come from IShares. QUAL is an equity ETF, while SCZ is a small-cap U.S. equity ETF. The overlap exists because both funds allocate meaningful weight to the same holdings. In this dataset, the biggest shared drivers are 066922519 and 066922477, which appear in both portfolios and push the overlap score higher.
Holding both QUAL and SCZ 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.
