IVV and VB: what people ask

questions4 answered

How much do IVV and VB overlap?

3.2% by weight, as of September 30, 2026: little overlap. 132 companies appear in both funds; they make up 3.2% of IVV and 23% of VB.

Which stocks do IVV and VB both hold?

The largest shared positions are MRNA, P, TWLO, ILMN and FLEX. Ranked by the smaller of the two weights, which is the part you would own twice.

Is it redundant to hold both IVV and VB?

Out of every $100 split evenly between them, about $3 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 372 names only in IVV, 1,169 only in VB. Half in each behaves like 163 equally weighted stocks, against 44 for IVV alone and 674 for VB alone. Whether that duplication is a problem depends on the mix you want; this is a description, not advice.

How is ETF overlap calculated here?

For every company held by both funds we take the smaller of its two weights and add them up. The weights come from the full holdings files iShares and Vanguard publish, not a top-10 sample, and companies are matched by their ISIN so share classes stay apart. Sector overlap applies the same rule to the issuers' sector labels; "behaves like N equally weighted stocks" is one over the sum of the squared weights.
