About These ETFs
What Stands Out In This Comparison
What This Means
QQQ is an equity ETF from Invesco, while SPTM is an equity ETF from SPDR. QQQ and SPTM 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 47.62%.
How They Differ
QQQ is an equity ETF from Invesco, while SPTM is an equity ETF from SPDR. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. SPTM has the lower expense ratio, while QQQ 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 37.9% 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 QQQ and SPTM are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. SPTM has the lower expense ratio, while QQQ charges more for its exposure.
