Vanguard Extended Market Index Fund Institutional Shares

This fund offers investors an economical and comprehensive avenue to access U.S. equities from companies outside the very largest corporations. Comprising roughly 3,000 distinct holdings, it provides significant diversification across numerous sectors, collectively representing approximately one-quarter of the total market capitalization of the American stock market. However, investors should be aware that its dedicated focus on these smaller-to-mid-sized companies means it is inherently subject to greater market volatility compared to funds concentrated on larger, more established corporations. This fund is specifically designed to act as an ideal counterpart to the Vanguard 500 Index Fund, as the combination of both vehicles delivers full, diversified representation across the entirety of the U.S. equity landscape.
