About These ETFs
What Stands Out In This Comparison
What This Means
IWB is an equity ETF from IShares, while VEA is an equity ETF from Vanguard. IWB and VEA 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 QSR.TO, STE, and RBA.TO.
How They Differ
IWB is an equity ETF from IShares, while VEA is an equity ETF from Vanguard. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. VEA has the lower expense ratio, while IWB 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 57.22% 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 IWB and VEA are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. VEA has the lower expense ratio, while IWB charges more for its exposure.
Overlap Driver Snapshot
Concentration
The top three shared holdings explain 57.22% of the full overlap score.

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
IWB is an equity ETF from IShares, while VEA is an equity ETF from Vanguard. The overlap exists because both funds allocate meaningful weight to the same holdings.
