What Stands Out In This Comparison

01

What This Means

ITOT is an equity ETF from IShares, while QQQM is an equity ETF from Invesco. ITOT and QQQM overlap enough to matter, but they still bring different exposures to a portfolio. The overlap is concentrated in holdings such as NVDA, AAPL, and MSFT, which explains why the score lands at 45.57%.

02

How They Differ

ITOT is an equity ETF from IShares, 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. ITOT 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 37.96% 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 ITOT and QQQM are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. ITOT has the lower expense ratio, while QQQM charges more for its exposure.

Overlap Driver Snapshot

Concentration

The top three shared holdings explain 37.96% 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

ITOT is an equity ETF from IShares, 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 ITOT and QQQM can still be reasonable, but you should expect some duplication. The decision comes down to whether the non-overlapping parts of each ETF are important enough for your strategy.
