BSV vs VCSH: 25% overlap
Vanguard Short-Term Bond ETF and Vanguard Short-Term Corporate Bond ETF share 25.5% of their portfolios by weight — computed as Σ min(wA, wB) over every holding both funds own.

Where BSV and VCSH 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 | BSV | VCSH | Δ |
|---|---|---|---|
| Treasuries | 69.4% | 0.4% | +69.0pp |
| Corporate — industrial & other | 12.6% | 50.5% | −37.8pp |
| Financials | 10.0% | 40.5% | −30.5pp |

| Sovereign | 0.8% | 0.0% | +0.8pp |
| Local Authority | 0.5% | 0.0% | +0.5pp |
Δ is BSV minus VCSH, in percentage points. Sector data is not published by every issuer, so “Unclassified” is a real category rather than a gap in the table.
What each fund holds alone
5.4% of BSV by weight, held in no part of VCSH.
0.6% of VCSH by weight, held in no part of BSV.
A large count with a small weight is the usual shape: the positions one fund adds are typically its smallest ones.
Concentration and cost
| BSV | VCSH | |
|---|---|---|
| Top 10 holdings | 73.8% | 14.7% |
| Positions held | 960 | 933 |
| Cost per $10,000 held, per year | $3 | $3 |
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.
Frequently asked
How much do BSV and VCSH overlap?
BSV and VCSH overlap 25.5% by portfolio weight — moderate overlap. They share 867 holdings. The figure comes from current issuer holdings files (BSV as of 2026-06-30, VCSH as of 2026-06-30).
How is the overlap between BSV and VCSH calculated?
As the sum of the smaller weight in each fund, over every holding both funds own: Σ min(wA, wB). If BSV holds a stock at 6% and VCSH holds the same stock at 4%, 4% counts as shared. The result is bounded between 0% and 100%, and it is computed after looking through any fund-of-funds to the underlying holdings.
Is it redundant to hold both BSV and VCSH?
That depends on your goals — we state facts, not advice. At 25.5% overlap, each fund still contributes meaningfully distinct exposure.

BSV holds 960 positions and VCSH holds 933; 93 of BSV's positions don't appear in VCSH at all, and they are 5.4% of BSV by weight.
