What Stands Out In This Comparison

01

What This Means

IGV is a technology-focused equity ETF from IShares, while VGT is a technology-focused equity ETF from Vanguard. IGV and VGT overlap enough to matter, but they still bring different exposures to a portfolio. The overlap is concentrated in holdings such as MSFT, ORCL, and PLTR, which explains why the score lands at 22.51%.

02

How They Differ

IGV is a technology-focused equity ETF from IShares, while VGT is a technology-focused equity ETF from Vanguard. IGV is the broader fund, while VGT is the more targeted sleeve. VGT has the lower expense ratio, while IGV 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 49.57% 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, IGV is usually the wider choice. If you want the more focused tilt, VGT is the narrower expression. VGT has the lower expense ratio, while IGV charges more for its exposure.

Overlap Driver Snapshot

Concentration

The top three shared holdings explain 49.57% 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

IGV is a technology-focused equity ETF from IShares, 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 MSFT, ORCL, and PLTR, which appear in both portfolios and push the overlap score higher.

Holding both IGV 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.

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.
