Compare another pair
Both funds come from SPDR. SPLG is a U.S. large-cap core ETF, while XLRE is a real estate ETF. SPLG and XLRE 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 WELL, PLD, and AMT.
Both funds come from SPDR. SPLG is a U.S. large-cap core ETF, while XLRE is a real estate ETF. SPLG is the broader fund, while XLRE is the more targeted sleeve. SPLG has the lower expense ratio, while XLRE 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 29.73% 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, XLRE is the narrower expression. SPLG has the lower expense ratio, while XLRE charges more for its exposure.
Concentration
The top three shared holdings explain 29.73% 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 XLRE.
