What Stands Out In This Comparison

01

What This Means

SPLG is a U.S. large-cap core ETF from SPDR, while VGT is a technology-focused equity ETF from Vanguard. SPLG and VGT 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 36.07%.

02

How They Differ

SPLG is a U.S. large-cap core ETF from SPDR, while VGT is a technology-focused equity ETF from Vanguard. SPLG is the broader fund, while VGT is the more targeted sleeve. SPLG has the lower expense ratio, while VGT 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 60.91% 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, VGT is the narrower expression. SPLG has the lower expense ratio, while VGT charges more for its exposure.

Overlap Driver Snapshot

Concentration

The top three shared holdings explain 60.91% 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

SPLG is a U.S. large-cap core ETF from SPDR, while VGT is a technology-focused equity ETF from Vanguard. 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 VGT 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.
