About These ETFs
What Stands Out In This Comparison
What This Means
Both funds come from IShares. IVV is a U.S. large-cap core ETF, while IVW is a U.S. growth equity ETF. IVV and IVW share a large chunk of the same portfolio weight. The overlap is driven by positions like NVDA, AAPL, and MSFT, so owning both may not diversify your stock exposure as much as the fund names suggest.
How They Differ
Both funds come from IShares. IVV is a U.S. large-cap core ETF, while IVW is a U.S. growth equity ETF. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. IVV has the lower expense ratio, while IVW 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 29.91% 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 IVV and IVW are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. IVV has the lower expense ratio, while IVW charges more for its exposure.
Overlap Driver Snapshot
Concentration
The top three shared holdings explain 29.91% 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
Both funds come from IShares. IVV is a U.S. large-cap core ETF, while IVW is a U.S. growth equity ETF. The overlap exists because both funds allocate meaningful weight to the same holdings. In this dataset, the biggest shared drivers are NVDA, AAPL, and MSFT, which appear in both portfolios and push the overlap score higher.
Holding both IVV and IVW may add less diversification than you expect. Many investors would choose the ETF that best matches their goal and avoid paying for duplicate exposure.
