About These ETFs
What Stands Out In This Comparison
What This Means
Both funds come from Invesco. QQQ is an equity ETF, while RSP is an equal-weight U.S. equity ETF. QQQ and RSP do not own much of the same portfolio weight. That usually means you are combining different parts of the market, with only a small amount of duplication through names like MU, WDC, and STX.
How They Differ
Both funds come from Invesco. QQQ is an equity ETF, while RSP is an equal-weight U.S. equity ETF. RSP is the broader fund, while QQQ is the more targeted sleeve. QQQ has the lower expense ratio, while RSP 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 5.04% 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
If you want the broader portfolio building block, RSP is usually the wider choice. If you want the more focused tilt, QQQ is the narrower expression. QQQ has the lower expense ratio, while RSP charges more for its exposure.

Why These ETFs Overlap
Both funds come from Invesco. QQQ is an equity ETF, while RSP is an equal-weight U.S. equity ETF. The overlap exists because both funds allocate meaningful weight to the same holdings. In this dataset, the biggest shared drivers are MU, WDC, and STX, which appear in both portfolios and push the overlap score higher.
Holding both QQQ and RSP can make sense if you want exposure to different sleeves of the market. The overlap is small enough that both funds may still improve diversification.
