Vanguard Morningstar Small-Cap Growth Index Fund Institutional Shares 

This affordably managed index fund offers exposure to dynamic U.S. small-capitalization growth companies, which frequently demonstrate more rapid expansion than the broader market. The fund's strategy is to replicate a growth-focused benchmark composed of smaller businesses. A primary concern for investors is the fund's concentrated investment in the small-cap sector, an area of the market known for its considerable volatility. Individuals seeking to add a passively managed, growth-oriented small-cap component to an already diversified investment portfolio may find this fund to be a suitable choice.
