What Stands Out In This Comparison

01

What This Means

Both funds come from IShares. IVW is a U.S. growth equity ETF, while IWF is a U.S. growth equity ETF. IVW and IWF share a large chunk of the same portfolio weight. The overlap is driven by positions like NVDA, MSFT, and AAPL, so owning both may not diversify your stock exposure as much as the fund names suggest.

02

How They Differ

Both funds come from IShares. IVW is a U.S. growth equity ETF, while IWF is a U.S. growth equity ETF. IVW is the broader fund, while IWF is the more targeted sleeve. IVW and IWF 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 39.33% 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, IVW is usually the wider choice. If you want the more focused tilt, IWF is the narrower expression. IVW and IWF are priced very similarly on expense ratio.

Overlap Driver Snapshot

Concentration

The top three shared holdings explain 39.33% 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

Both funds come from IShares. IVW is a U.S. growth equity ETF, while IWF is a U.S. growth equity ETF. 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 IVW and IWF may add less diversification than you expect. Many investors would choose the ETF that best matches their goal and avoid paying for duplicate exposure.

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.
