There are a number of U.S. mutual funds available, but some of the most desirable and well known examples are offered by Vanguard (the Vanguard 500 Index Investor Fund), American Funds (American Funds Growth Fund of America), and Fidelity (Fidelity Contrafund). A number of companies, such as Vanguard and American Funds, also have a selection of mutual fund products available.
Vanguard mutual funds are geared towards larger stocks on the S&P 500 (the Index Investor Fund), as well as corporate bonds and the U.S. Treasury, covered by the Total Bond Market Index. While these two are more specialized, Vanguard also offers the Total Stock Market Index Fund, which passively covers a much more general range of stock sizes and values.
American Funds has two popular mutual funds available. The EuroPacific Growth fund concentrates on Pacific and European assets, as well as a fair share of emerging markets, while the Growth Fund of America is focused on common stocks, although a small share is also devoted to international assets.
The Fidelity Contrafund is another mutual fund that is focused on U.S. markets, although just over 10 percent of the fund is also geared towards well developed international markets as well. The fund itself is cheaper than some competitors, and lends itself towards strong 10-year performance.
