IVV vs SCHB: 85% overlap
iShares Core S&P 500 ETF and Schwab U.S. Broad Market ETF share 85.2% of their portfolios by weight — computed as Σ min(wA, wB) over every holding both funds own.
Different holding dates. These holdings were published about 2 months apart — SCHB as of 2026-05-31, the rest through 2026-07-23. 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 1.1. Two funds that shared nothing would score 2.0; two identical funds score 1.0.
