What Stands Out In This Comparison

01

What This Means

EFA is an equity ETF from IShares, while VUG is a U.S. growth equity ETF from Vanguard. EFA and VUG 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 866966104.

02

How They Differ

EFA is an equity ETF from IShares, while VUG is a U.S. growth equity ETF from Vanguard. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. VUG has the lower expense ratio, while EFA 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 100% 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 EFA and VUG are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. VUG has the lower expense ratio, while EFA charges more for its exposure.

Overlap Driver Snapshot

Concentration

The top three shared holdings explain 100% 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.

Top Shared Holdings

These are the holdings contributing the most to the overlap score between EFA and VUG.

Why These ETFs Overlap

EFA is an equity ETF from IShares, while VUG is a U.S. growth 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 866966104, which appear in both portfolios and push the overlap score higher.

Holding both EFA and VUG 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

For every stock that appears in both ETFs, we take the smaller of the two weights. Adding up all those minimums gives the total overlap percentage. A score of 100% means the two ETFs hold the exact same stocks in the same proportions.
