About These ETFs
What Stands Out In This Comparison
What This Means
Both funds come from Vanguard. MGK is a U.S. growth equity ETF, while VUG is a U.S. growth equity ETF. MGK and VUG 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
Both funds come from Vanguard. MGK is a U.S. growth 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. VUG has the lower expense ratio, while MGK 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 39.45% 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 MGK 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 MGK charges more for its exposure.
Overlap Driver Snapshot
Concentration
The top three shared holdings explain 39.45% 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. MGK is a U.S. growth equity ETF, while VUG 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 MGK and VUG is usually redundant unless you have a very specific reason to tilt toward their shared holdings. In most cases, one ETF is enough.
