VANGUARD INDEX FUNDS VANGUARD MID-CAP GROWTH ETF

The Vanguard Mid-Cap Growth ETF employs an indexing investment approach designed to track the performance of the CRSP US Mid Cap Growth Index, a broadly diversified index of growth stocks of mid-size U.S. companies. The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.
