Compare another pair
IWF is a U.S. growth equity ETF from IShares, while VUG is a U.S. growth equity ETF from Vanguard. IWF and VUG are closely aligned. A large share of their portfolio weight is invested in the same companies, especially NVDA, AAPL, and GOOGL, which means holding both is likely to feel similar to increasing the size of one core position.
IWF is a U.S. growth equity ETF from IShares, while VUG is a U.S. growth equity ETF from Vanguard. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. VUG has the lower expense ratio, while IWF charges more for its exposure.
The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 32.22% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.
Because IWF and VUG are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. VUG has the lower expense ratio, while IWF charges more for its exposure.
Concentration
The top three shared holdings explain 32.22% 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.
These are the holdings contributing the most to the overlap score between IWF and VUG.
