Where VT and VTI 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 | VT | VTI | Δ |
|---|---|---|---|
| Information Technology | 30.1% | 35.2% | −5.1pp |
| Unclassified | 3.8% | 0.2% | +3.6pp |

Δ is VT minus VTI, 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
36.0% of VT by weight, held in no part of VTI.
1.7% of VTI by weight, held in no part of VT.
A large count with a small weight is the usual shape: the positions one fund adds are typically its smallest ones.
