Vanguard Extended Market Index Fund Institutional Plus Shares 

This fund offers investors an economical method to achieve extensive diversification across the U.S. mid- and small-capitalization stock segments within a single investment vehicle. It encompasses approximately 3,000 individual stocks, spanning various industries and collectively representing roughly one-fourth of the overall market value of the U.S. stock market. A principal risk factor stems from its dedicated focus on these mid- and small-cap markets, which historically exhibit greater price volatility compared to their large-cap counterparts. Designed to work in conjunction with the Vanguard 500 Index Fund, these two funds combined offer comprehensive coverage of the entire U.S. equity market.
