What Stands Out In This Comparison

01

What This Means

Both funds come from IShares. IWB is an equity ETF, while QUAL is an equity ETF. IWB and QUAL overlap enough to matter, but they still bring different exposures to a portfolio. The overlap is concentrated in holdings such as NVDA, AAPL, and MSFT, which explains why the score lands at 44.5%.

02

How They Differ

Both funds come from IShares. IWB is an equity ETF, while QUAL is an equity ETF. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. IWB and QUAL 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 38.62% 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 IWB and QUAL are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. IWB and QUAL are priced very similarly on expense ratio.

Overlap Driver Snapshot

Concentration

The top three shared holdings explain 38.62% 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 IWB and QUAL.

Why These ETFs Overlap

Both funds come from IShares. IWB is an equity ETF, while QUAL is an equity ETF. The overlap exists because both funds allocate meaningful weight to the same holdings. In this dataset, the biggest shared drivers are NVDA, AAPL, and MSFT, which appear in both portfolios and push the overlap score higher.

Holding both IWB and QUAL 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.
