BIV vs IVE: 0% overlap
Vanguard Intermediate-Term Bond ETF and iShares S&P 500 Value ETF share 0.1% of their portfolios by weight — computed as Σ min(wA, wB) over every holding both funds own.
Different holding dates. These holdings were published 27 days apart — BIV as of 2026-06-30, the rest through 2026-07-27. Each fund is compared using its most recent file, so any trading in between shows up as a difference.
You would hold two tickers and get the diversification of 2.0. Two funds that shared nothing would score 2.0; two identical funds score 1.0.

Δ is BIV minus IVE, in percentage points. Sector data is not published by every issuer, so “Unclassified” is a real category rather than a gap in the table.
