About These ETFs
What Stands Out In This Comparison
What This Means
SCZ is a small-cap U.S. equity ETF from IShares, while VWO is an emerging-markets equity ETF from Vanguard. SCZ and VWO 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 1860.HK, 0327.HK, and 1112.HK.
How They Differ
SCZ is a small-cap U.S. equity ETF from IShares, while VWO is an emerging-markets equity ETF from Vanguard. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. VWO has the lower expense ratio, while SCZ 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 80% 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 SCZ and VWO are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. VWO has the lower expense ratio, while SCZ charges more for its exposure.
Overlap Driver Snapshot
Concentration
The top three shared holdings explain 80% 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
