SCHX vs VO: 15% overlap
Schwab U.S. Large-Cap ETF and Vanguard Mid-Cap ETF share 15.4% of their portfolios by weight — computed as Σ min(wA, wB) over every holding both funds own.
Different holding dates. These holdings were published 30 days apart — SCHX as of 2026-05-31, the rest through 2026-06-30. 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 1.8. Two funds that shared nothing would score 2.0; two identical funds score 1.0.

Where SCHX and VO differ
Sector weights as a share of each fund, ordered by the size of the gap rather than the size of the sector — two funds that overlap heavily still usually diverge somewhere.
| Sector | SCHX | VO | Δ |

| Information Technology | 36.8% | 16.1% | +20.7pp |
| Industrials | 8.2% | 19.6% | −11.4pp |

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

84.5% of SCHX by weight, held in no part of VO.
7.9% of VO by weight, held in no part of SCHX.
A large count with a small weight is the usual shape: the positions one fund adds are typically its smallest ones.

Cost is the expense ratio applied to $10,000; it excludes any brokerage commission, bid-ask spread or tax consequence. Figures are facts about the funds, not a suggestion about which to hold.
