About These ETFs
What Stands Out In This Comparison
What This Means
Both funds come from Vanguard. VB is a small-cap U.S. equity ETF, while VUG is a U.S. growth equity ETF. VB and VUG 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 TER, EQT, and INSM.
How They Differ
Both funds come from Vanguard. VB is a small-cap U.S. equity ETF, while VUG 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. VB and VUG 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 45.42% 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 VB and VUG are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. VB and VUG are priced very similarly on expense ratio.
Overlap Driver Snapshot
Concentration
The top three shared holdings explain 45.42% 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 Vanguard. VB is a small-cap U.S. equity ETF, while VUG is a U.S. growth equity ETF. The overlap exists because both funds allocate meaningful weight to the same holdings.
