Compare another pair
Both funds come from SPDR. SPLG is a U.S. large-cap core ETF, while XLK is a technology-focused equity ETF. SPLG and XLK overlap enough to matter, but they still bring different exposures to a portfolio. The overlap is concentrated in holdings such as NVDA, MSFT, and AAPL, which explains why the score lands at 35.86%.
Both funds come from SPDR. SPLG is a U.S. large-cap core ETF, while XLK is a technology-focused equity ETF. SPLG is the broader fund, while XLK is the more targeted sleeve. SPLG has the lower expense ratio, while XLK charges more for its exposure.
The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 61.97% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.
If you want the broader portfolio building block, SPLG is usually the wider choice. If you want the more focused tilt, XLK is the narrower expression. SPLG has the lower expense ratio, while XLK charges more for its exposure.
Concentration
The top three shared holdings explain 61.97% 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.
These are the holdings contributing the most to the overlap score between SPLG and XLK.

Both funds come from SPDR. SPLG is a U.S. large-cap core ETF, while XLK is a technology-focused equity ETF. The overlap exists because both funds allocate meaningful weight to the same holdings. In this dataset, the biggest shared drivers are NVDA, MSFT, and AAPL, which appear in both portfolios and push the overlap score higher.
Holding both SPLG and XLK 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.
