What Stands Out In This Comparison

01

What This Means

Both funds come from SPDR. SPLG is a U.S. large-cap core ETF, while XLV is a health care sector ETF. SPLG and XLV 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 LLY, JNJ, and ABBV.

02

How They Differ

Both funds come from SPDR. SPLG is a U.S. large-cap core ETF, while XLV is a health care sector ETF. SPLG is the broader fund, while XLV is the more targeted sleeve. SPLG has the lower expense ratio, while XLV charges more for its exposure.

03

What Drives The Overlap

The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 28.53% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.

04

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, XLV is the narrower expression. SPLG has the lower expense ratio, while XLV charges more for its exposure.

Overlap Driver Snapshot

Concentration

The top three shared holdings explain 28.53% 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.

Why These ETFs Overlap

Both funds come from SPDR. SPLG is a U.S. large-cap core ETF, while XLV is a health care sector ETF. The overlap exists because both funds allocate meaningful weight to the same holdings.

Holding both SPLG and XLV 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.
