What Stands Out In This Comparison
What This Means
Both funds come from SPDR. SPLG is a U.S. large-cap core ETF, while XLB is an equity ETF. SPLG and XLB 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 LIN, NEM, and SHW.
How They Differ
Both funds come from SPDR. SPLG is a U.S. large-cap core ETF, while XLB is an equity ETF. SPLG is the broader fund, while XLB is the more targeted sleeve. SPLG has the lower expense ratio, while XLB 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 38.15% 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, SPLG is usually the wider choice. If you want the more focused tilt, XLB is the narrower expression. SPLG has the lower expense ratio, while XLB charges more for its exposure.
