About VIMSX

Vanguard Mid-Cap Index Fund Investor Shares is a mutual fund designed to replicate the performance of the CRSP US Mid Cap Index, which covers a broad spectrum of medium-sized U.S. companies. This fund employs a passive management strategy, aiming to deliver returns in line with its benchmark by investing in a diversified portfolio of mid-cap stocks. These stocks typically represent companies that are well-established but not dominant in their industries, offering a balance of growth potential and financial stability. Notable features of this fund include its extensive diversification—holding over 300 stocks—with no significant concentration in any single company or sector. The fund's portfolio closely mirrors the sector weights and style of its peer group, while its market-cap weighted approach helps reduce unnecessary trading and associated costs. With a relatively low expense ratio of 0.17% and a minimum investment requirement of $3,000, the fund is recognized for its cost efficiency. Regular quarterly dividends and a disciplined approach to turnover further enhance its appeal. In the broader market context, this fund offers investors core exposure to U.S. mid-cap equities, serving as a foundational holding in diversified portfolios seeking to capture the growth dynamics of mid-sized firms.
