What Are Some Mutual Funds Offered by Vanguard?

Vanguard offers approximately 160 U.S. funds and 120 international funds as of Dec. 31 2014, according to the company's website. Some of its largest funds include the Vanguard Total Stock Market Fund, which takes a passive approach to investing and comprises a wide range of small to large American companies, and the Vanguard 500 Index Fund, which is also a passive fund and simply attempts to replicate the composition and performance of the Standard and Poor's 500 Index, notes MutualFunds.com.

As of late 2015, some of Vanguard's best funds include the Vanguard Wellesley Income fund, the Vanguard Equity Income Fund and Vanguard Mid Cap Index Fund, explains Kent Thune for InvestorPlace. The Wellesley Income Fund offers a heavy proportion of exposure to bonds, has performed well over medium- to long-term timeframes and is well suited to conservative investors in a bearish market. The Equity Income Fund is also conservative and offers exposure to a diverse range of industries, including companies such as Verizon, Johnson & Johnson and Wells Fargo. The Mid Cap Index Fund is especially well suited to long-term investors, with its performance beating out the S&P 500 considerably for more than five years.

The total amount of assets under Vanguard's management is approximately $3 trillion and comes from 20 million investors, states the Vanguard website. Its funds maintain an average expense ratio of 0.18 percent of net assets.
