Vanguard Morningstar Small-Cap Growth Index Fund Admiral Shares 

This cost-efficient index-based fund provides investment exposure to growth-oriented, smaller American companies, which generally exhibit quicker expansion than the broader market. Its primary goal is to mirror the performance of a growth-focused benchmark comprised of U.S. firms with smaller market capitalizations. A significant risk of this fund is its specialized concentration in the small-cap segment, an area of the market often characterized by considerable price fluctuations. Individuals aiming to incorporate a passively managed allocation to small-cap growth within an already varied investment portfolio may find this fund a suitable choice.
