About These ETFs
What Stands Out In This Comparison
What This Means
IVW is a U.S. growth equity ETF from IShares, while RSP is an equal-weight U.S. equity ETF from Invesco. IVW and RSP 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 SNDK, MU, and HWM.
How They Differ
IVW is a U.S. growth equity ETF from IShares, while RSP is an equal-weight U.S. equity ETF from Invesco. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. IVW has the lower expense ratio, while RSP 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 4.45% 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 IVW and RSP are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. IVW has the lower expense ratio, while RSP charges more for its exposure.
Overlap Driver Snapshot
Concentration
The top three shared holdings explain 4.45% 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
IVW is a U.S. growth equity ETF from IShares, while RSP is an equal-weight U.S. equity ETF from Invesco. The overlap exists because both funds allocate meaningful weight to the same holdings.

Holding both IVW and RSP 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.
