The 4 Best Total Market Index Funds

A total stock market index fund is an investment vehicle that contains a basket of stocks within a mutual fund or exchange traded fund (ETF) that tracks an equity index. An equity index contains numerous stocks across various industries designed to represent the performance of the overall equity market. However, investors can't buy an index directly, but instead, can invest in a fund that mirrors a broad-based index, such as the Russell 3000 Index, the S&P 500, or the Wilshire 5000 Total Market Index.

By investing in stocks linked to a given index—called a benchmark—a total market index fund's performance aims to mirror the equities within the underlying. The stocks within these funds may include those issued by large, well-known corporations and stocks of smaller, lesser-known companies.

In this article, we highlight four of the most prominent total market index funds, including their one-year performance, investment minimums, and the expense ratio for each of the funds.
