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.

How it has done
VITNX share class · total returns with dividends reinvested
Volatility over the last 12 months: 12.91%. Past returns are a record, not a forecast.
Jun 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.
The 2 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.03% | +29.87% | +87.27% | +83.46% | -9.07% | |
| 0.02% | +29.89% | +87.34% | +83.54% | -9.08% |
These classes hold the same portfolio, so the 0.07pp spread over 5 years is the cost difference between them — roughly 0.01pp a year — not a difference in what they own.
