What Stands Out In This Comparison

01

What This Means

SPTM is an equity ETF from SPDR, while VEA is an equity ETF from Vanguard. SPTM and VEA 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 STE, SCI, and SATS.

02

How They Differ

SPTM is an equity ETF from SPDR, while VEA is an equity ETF from Vanguard. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. SPTM and VEA are priced very similarly on expense ratio.

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 73.75% 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

Because SPTM and VEA are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. SPTM and VEA are priced very similarly on expense ratio.

Overlap Driver Snapshot

Concentration

The top three shared holdings explain 73.75% 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

SPTM is an equity ETF from SPDR, while VEA is an 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 STE, SCI, and SATS, which appear in both portfolios and push the overlap score higher.

Holding both SPTM and VEA 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.

How Overlap Is Calculated

A straightforward approach used by portfolio analysts.

Overlap = sum(min(Weight_A, Weight_B)) for each shared holding
