About These ETFs
What Stands Out In This Comparison
What This Means
IWR is a mid-cap U.S. equity ETF from IShares, while VTV is a U.S. value equity ETF from Vanguard. IWR and VTV overlap enough to matter, but they still bring different exposures to a portfolio. The overlap is concentrated in holdings such as WDC, BK, and CMI, which explains why the score lands at 21.08%.
How They Differ
IWR is a mid-cap U.S. equity ETF from IShares, while VTV is a U.S. value equity ETF from Vanguard. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. VTV has the lower expense ratio, while IWR 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 4.79% 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 IWR and VTV are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. VTV has the lower expense ratio, while IWR charges more for its exposure.

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.
