Fund profile
As filed in the prospectus · 2026 Q2
Vanguard Institutional Total Stock Market Index Fund (the Fund) seeks to track the performance of a benchmark index that measures the investment return of the overall stock market.
The fund tracks the CRSP US Total Market Index using a sampling approach, holding a range of securities that approximate the full index in terms of key risk factors and characteristics. Because the fund samples rather than holds all index constituents, its returns may diverge from the index.

The outer band is exposure held short — written against the portfolio rather than part of it, which is why it sits outside the ring and why the two are never netted into one figure.
Derivatives are shown at market value, not notional exposure.

Mar 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
