iShares Core S&P Mid-Cap ETF and Schwab U.S. Broad Market ETF share 4.7% 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.
