Process & Management
Process
Vanguard Mid-Cap Index Fund seeks to track the investment performance of the CRSP US Mid Cap Index, an unmanaged benchmark representing medium-size U.S. firms. Using full replication, the portfolio holds all stocks in the same capitalization weighting as the index. The experience and stability of Vanguard’s Equity Index Group have permitted continuous refinement of techniques for reducing tracking error. The group uses proprietary software to implement trading decisions that accommodate cash flow and maintain close correlation with index characteristics. Vanguard’s refined indexing process, combined with low management fees and efficient trading, has provided tight tracking, net of expenses.

An investment in the fund could lose money over short or even long periods. You should expect the fund’s share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. The fund’s performance could be hurt by:
- Stock market risk: The chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising stock prices and periods of falling stock prices. The fund’s target index may, at times, become focused in stocks of a particular sector, category, or group of companies. Because the fund seeks to track its target index, the fund may underperform the overall stock market.
- Investment style risk: The chance that returns from mid-capitalization stocks will trail returns from the overall stock market. Historically, mid-cap stocks have been more volatile in price than the large-cap stocks that dominate the overall market, and they often perform quite differently. Mid-cap stocks tend to have greater volatility than large-cap stocks because, among other things, medium-size companies are more sensitive to changing economic conditions.
- Index-related risks: The fund is subject to risks associated with index investing, which include passive management risk, tracking error risk, and index provider risk. Passive management risk is the chance that the fund's use of an indexing strategy will negatively impact the fund's performance. Because the fund seeks to track the performance of its target index regardless of how that index is performing, the fund's performance may be lower than it would be if the fund were actively managed. Tracking error risk is the chance that the fund's performance will deviate from the performance of its target index. Tracking error risk may be heightened during times of increased market volatility or under other unusual market conditions. Index provider risk is the chance that the fund will be negatively impacted by changes or errors made by the index provider. Any gains, losses, or costs associated with or resulting from an error made by the index provider will generally be borne by the fund and, as a result, the fund's shareholders.

The performance data shown represents past performance, which is not a guarantee of future results. Investment returns and principal value will fluctuate, so that investors' shares, when sold, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data cited.
Performance data for periods of less than one year does not reflect the deduction of purchase and redemption fees. Maintenance, low balance, and service fees may be assessed by some funds. None of these fees are reflected in the performance figures. If these fees were included, the performance would be lower. All other performance data are adjusted for purchase and redemption fees, where applicable. See Fees & Costs below for expense ratio and additional fee details.
The performance of an index is not an exact representation of any particular investment, as you cannot invest directly in an index. Benchmark comparative indexes represent unmanaged or average returns on various financial assets, which can be compared with funds' total returns for the purpose of measuring relative performance.
