Before diving into the best total stock market index funds, we'll review the definition and primary features so you'll know if these mutual funds are appropriate for you and your investment goals.
Here's what to know about total stock index funds:
Total Stock Market Fund Definition
A total stock market index fund is a mutual fund that invests in a basket of stocks that will closely mirror the stock holdings and performance of a broad stock market benchmark, such as The Wilshire 5000 or The Russell 3000, that represents a large portion of the U.S. or international stock market. For example,the holdings in the Wilshire 5000 and Russell 3000 include most of the domestic U.S. stock holdings traded on stock exchanges, which is why the "total market" name is usually included in the fund name.
Like S&P 500 Index Funds, the Wilshire 5000 is market-cap weighted, which means that larger companies (those with larger capitalization) will represent a larger portion (which means among the top holdings) by percentage than the smaller companies. For example, the top holdings in the Wilshire 5000 will include big companies like Apple (AAPL), Facebook (FB), and Microsoft (MSFT).
Some total stock index funds focus on stocks outside of the U.S. These funds typically track an international stock index like the FTSE Global All Cap ex US Index.
Should You Use a Total Stock Market Index Fund?
Often, the primary purpose of using a Total Stock Market Index Fund is as a core holding in a portfolio of mutual funds (i.e. Core and Satellite Portfolio Strategy). The reason for this is that investors can gain access to the entire U.S. stock market in one low-cost fund. They can then build around that core with other holdings representing different categories.
Many investors may also use one of the best S&P 500 Index Funds as core holdings because the performance compared to Total Stock Market Index Funds is similar (due to the heavy weighting of large cap stocks in the top holdings). However, Total Stock Market Index funds offer more diversification than S&P 500 Index funds. In addition to the largest U.S. stocks, you'll also get small- and mid-cap stocks in the total stock index.
Therefore, there will be some mid-cap and small-cap holdings in a Total Stock Market Index Fund so there may be some overlap with other funds in your portfolio. For this reason, many investors prefer using an S&P 500 Index Fund, combined with a separate small-cap index fund, to achieve optimal diversification. So, if you use a total stock index fund, be sure to find other holdings in diverse categories.
