What Stands Out In This Comparison

01

What This Means

MGK is a U.S. growth equity ETF from Vanguard, while QQQM is an equity ETF from Invesco. MGK and QQQM share a large chunk of the same portfolio weight. The overlap is driven by positions like NVDA, AAPL, and MSFT, so owning both may not diversify your stock exposure as much as the fund names suggest.

02

How They Differ

MGK is a U.S. growth equity ETF from Vanguard, while QQQM is an equity ETF from Invesco. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. MGK has the lower expense ratio, while QQQM charges more for its exposure.

03

What Drives The Overlap

The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 36.09% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.

04

When One May Fit Better

Because MGK and QQQM are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. MGK has the lower expense ratio, while QQQM charges more for its exposure.

Overlap Driver Snapshot

Concentration

The top three shared holdings explain 36.09% 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

MGK is a U.S. growth equity ETF from Vanguard, while QQQM is an equity ETF from Invesco. 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 QQQM may add less diversification than you expect. Many investors would choose the ETF that best matches their goal and avoid paying for duplicate exposure.

How Overlap Is Calculated

A straightforward approach used by portfolio analysts.

Overlap = sum(min(Weight_A, Weight_B)) for each shared holding

For every stock that appears in both ETFs, we take the smaller of the two weights. Adding up all those minimums gives the total overlap percentage. A score of 100% means the two ETFs hold the exact same stocks in the same proportions.
