About These ETFs
What Stands Out In This Comparison
What This Means
SPY is a U.S. large-cap core ETF from SPDR, while VV is a large-cap U.S. equity ETF from Vanguard. SPY and VV are closely aligned. A large share of their portfolio weight is invested in the same companies, especially NVDA, AAPL, and MSFT, which means holding both is likely to feel similar to increasing the size of one core position.
How They Differ
SPY is a U.S. large-cap core ETF from SPDR, while VV is a large-cap U.S. equity ETF from Vanguard. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. VV has the lower expense ratio, while SPY 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 20.59% 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 SPY and VV are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. VV has the lower expense ratio, while SPY charges more for its exposure.
Overlap Driver Snapshot
Concentration
The top three shared holdings explain 20.59% 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
SPY is a U.S. large-cap core ETF from SPDR, while VV is a large-cap U.S. equity ETF from Vanguard. 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 SPY and VV is usually redundant unless you have a very specific reason to tilt toward their shared holdings. In most cases, one ETF is enough.
