Index funds are passive investments. They track an index with the goal of replicating the performance of that index, minus expenses. Active funds, meanwhile, are led by managers who choose particular securities in an effort to outperform an index.

However, some index funds are better than others. The best index funds do a good job of closely tracking their indexes, minimizing costs, and following sensible rules-based indexes.

Why Are Index Funds Such a Popular Investing Option?

The first index fund, Vanguard 500, debuted in 1976. Since then, funds that index the US stock market have exploded in popularity. And index funds that focus on international stocks and bonds are becoming more popular, too.

Why? Many argue that buying and holding the broad market (whatever that market may be) generates better results than trying to beat that same market through actively selecting securities. Indeed, Morningstar research has confirmed that in many investment categories, index funds have outperformed active funds over time.

Best Index Funds to Buy in 2024

A good place to start your search for top index exchange-traded funds and mutual funds is with the Morningstar Medalist Rating. Funds that earn our highest rating—Gold—are those that we think are most likely to outperform over a full market cycle.

Here’s the list of best low-cost index mutual funds and ETFs for 2024, which is broken down by the three main asset classes that are represented in many investors’ portfolios: US stocks, international stocks, and bonds. We’re also including a list of what we’re calling “specialized” index funds, which features top-rated low-cost index funds from investment categories that appear less frequently in the portfolios of most investors.

Although this is a list of the best broad-based low-cost index funds investing in us stocks, there is some variety here. Several funds in the group track the S&P 500 and therefore provide access to large-cap stocks representing about 80% of the US stock market. Other index funds on the list follow much broader market indexes that include more stocks, some of which are smaller-cap names. Meanwhile, other funds on the list are more narrowly focused, tracking indexes based on market capitalization (mid- or small-cap stocks) or investment style (growth stocks or value stocks).

3 Great Emerging-Markets ETFs for 2024

Here are some good options in an otherwise tough category.

Best Bond Index Funds

These mutual funds and ETFs all land in one of the broad bond categories, earn the top Morningstar Medalist Rating of Gold, and have Analyst Assigned % equaling at least 80% as of April 2, 2024.

  1. Fidelity us Bond Index FXNAX
  2. iShares Core Total USD Bond Market ETF IUSB

  11. Vanguard Tax-Exempt Bond ETF VTEB
  12. Vanguard Total Bond Market ETF/Index BND VBTIX

Several of the best broad-based index funds on this list land in one of the intermediate-term bond categories. As such, they’d make great choices to anchor the bond portion of an investor’s portfolio, assuming the goals for the money are six or more years away. Those saving for a shorter-term goal in the next three to five years might consider short-term bond funds instead. Those investors with longer time horizons might consider a longer-term bond fund—but they should also be prepared for the enhanced volatility that comes with investing in long-term bonds.

Top Low-Cost Index Funds: Specialized

These mutual funds and ETFs all land in one of the specialized stock or bond categories, earn the top Morningstar Medalist Rating of Gold, and have Analyst Assigned % equaling at least 80% as of April 2, 2024.

  1. Schwab us TIPS ETF SCHP
  2. Vanguard FTSE Europe ETF/Vanguard European Stock Index VGK VEUSX
  3. Vanguard Short-Term Inflation-Protected Securities ETF/Index VTIP VTAPX

The top-rated mutual funds and ETFs on this list are good choices for investors looking to fill more niche roles in their portfolios. For instance, retirees often hold a fund that’s meant to blunt the impact of inflation on their portfolios; two funds on this list are designed to do just that.

How to Find the Best Index Funds

Of course, focusing on funds that earn a Gold rating may be too limiting for some investors. Those who’d like to consider funds beyond our top rating can review a full list of US stock index funds and ETFs and bond index funds and ETFs that earn ratings of Bronze, Silver, and Gold.

Investors can also review complete lists of all index mutual funds or all index ETFs. These lists include funds that don’t currently earn Medalist Ratings.

The Benefits of Investing in Index Funds

Any historical performance advantage aside, there are several benefits to investing in index funds.

  • Index funds are usually lower in cost than similar actively managed funds.
  • Index funds perform like the market they’re tracking; as such, there aren’t many surprises in performance.
  • Index funds don’t face “key-person risk,” which means that manager changes aren’t a big deal, since there’s no active security selection involved.
  • Index funds are often more tax-friendly than similar active funds.

Should You Invest in an Index Mutual Fund or ETF?

Investors can access passive strategies through two different investment products: mutual funds or exchange-traded funds.

One product isn’t better than the other; choosing the right wrapper depends on personal preferences. Investors who value trading flexibility or who may have few dollars to invest might prefer an ETF, while those accessing index funds via a company-sponsored retirement plan are more than likely buying mutual funds.
