About These ETFs
What Stands Out In This Comparison
What This Means
IJR is a small-cap U.S. equity ETF from IShares, while VWO is an emerging-markets equity ETF from Vanguard. IJR 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 BHE, STC, and AL.
How They Differ
IJR 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. IJR and VWO are priced very similarly on expense ratio.
What Drives The Overlap
The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 81.35% 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 VWO are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. IJR and VWO are priced very similarly on expense ratio.
Overlap Driver Snapshot
Concentration

Shared Sector Tilt
