Vanguard Morningstar Growth Index Fund;Institutional

This passively managed, cost-efficient index fund aims to mirror the performance of its broad benchmark by holding nearly all of the underlying securities. It concentrates its investments in shares of sizable American corporations operating within industries that exhibit above-average growth potential compared to the overall market, employing a long-term, low-turnover approach. Beyond the inherent fluctuations of the stock market, a significant risk factor stems from its concentrated exposure to large-capitalization growth equities, which could periodically lag behind the performance of the broader market. For three-quarters of its total assets, the fund is generally prohibited from acquiring more than 10% of any single issuer's outstanding voting stock, nor can it allocate over 5% of its total assets to the securities of any one issuer. An exception to these rules is made when necessary to closely replicate the structure of its benchmark index. These restrictions do not, however, apply to investments in debt instruments issued by the U.S. government or its associated agencies.
