Vanguard Mid-Cap Growth Index Fund Investor Shares

This fund endeavors to replicate the investment returns of the CRSP US Mid Cap Growth Index, which measures the performance of mid-capitalization growth-oriented companies. Employing an indexing methodology, the fund aims to mirror this broadly diversified benchmark, consisting of growth stocks from mid-sized U.S. businesses. The advisor accomplishes this by investing nearly all of the fund's assets directly into the index's constituent stocks, holding each in a proportion closely aligned with its weighting within the index.
