Fund info

Vanguard Mid-Cap Index Fund Institutional Plus Shares is a mutual fund that aims to replicate the performance of the CRSP US Mid Cap Index, a benchmark representing medium-sized U.S. companies. This fund provides institutional investors with broad, diversified exposure to the mid-cap segment of the U.S. equity market, encompassing companies across various sectors such as technology, industrials, real estate, utilities, and financial services. Notable holdings include Amphenol Corporation, Constellation Energy, and TransDigm Group, with the top ten holdings comprising about 9% of total assets. The fund is characterized by its low expense ratio of 0.03%, minimal turnover, and a high degree of diversification—features that help manage costs and reduce volatility over time. With a substantial minimum initial investment, it primarily serves large institutional clients. Its primary role in the financial market is to offer efficient, low-cost access to the growth and return potential of mid-cap stocks, thereby allowing investors to diversify beyond large-cap equities while retaining broad-based U.S. market exposure.
