AGG vs SCHG: 0% overlap
iShares Core U.S. Aggregate Bond ETF and Schwab U.S. Large-Cap Growth 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 about 2 months apart — SCHG 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 2.0. Two funds that shared nothing would score 2.0; two identical funds score 1.0.

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