Index funds try to match the returns of the index they’re tracking, such as the S&P 500, and are a form of passive investing. You can use index funds to simplify your investment strategy and grow your wealth over time.

The best index funds have low costs and a history of closely matching the returns of the index they follow. If you’re new to investing in index funds, take time to learn how they work, the benefits and some of the best available funds.

Vault’s Viewpoint on Index Funds

  • An index fund is an investment fund that tries to reproduce the returns of the fund it’s tracking.
  • Index funds are a form of passive investing and offer investors greater portfolio diversification with low risk.
  • To open an index fund, you’ll start by opening a brokerage account and choosing your index fund.

What Is an Index Fund?

An index fund is an investment fund that tries to match the returns of an index like the S&P 500. An index is made up of a group of companies representing a segment of the financial market. For example, the S&P 500 is made up of the 500 U.S. companies with the highest market capitalization rates.

An index fund is made up of the same investments as the index it tracks, so it closely mirrors the performance of that fund. Many people prefer index funds because they’re a passive form of investing and little hands-on management is necessary.

Benefits of Index Funds

Index funds use a buy-and-hold strategy, which means you buy the fund and keep it for a long time. Here are some of the biggest benefits of index fund investing:

  • Good for beginners: Investing in index funds doesn’t require a lot of financial knowledge, so it’s a good choice for anyone new to investing.
  • Low cost: Index funds have lower management fees than actively managed funds.
  • Diversification: Because an index fund holds a wide variety of stocks, it’s a good way to diversify your portfolio. It would be hard to build and maintain a similar portfolio on your own.
  • Long-term growth potential: Index funds are best for individuals who want to grow their investments over the long term. The market will always have its ups and downs, but the S&P 500 continues to earn an average annual return of nearly 10%.

The Best Index Funds

You should take some time to research any funds you’re considering putting money into. If you’re not sure where to start, here are four of the best index funds to consider.

Vanguard 500 Index Fund – Admiral Shares (VFIAX)

VFIAX tracks the S&P 500 and aims to replicate its returns. It’s a large-blend index fund, making it fairly representative of the overall market. Microsoft, Apple, and Amazon are some of the firm’s top holdings.

Over the last five years, VFIAX has delivered an average annual return of 15.65%, which is only slightly below the benchmark. It also comes with a low expense ratio of 0.04%. But it does come with a $3,000 minimum investment. So it won’t be the best choice for someone with limited capital.

Fidelity 500 Index Fund (FXAIX)

FXAIX is an index fund offered by Fidelity, and it’s a large-blend fund that tracks the S&P 500. Information technology is its top sector and accounts for over 29% of its stocks. With a 2% turnover rate, FXAIX makes fewer trades compared to similar funds.

The expense ratio is 0.015%, making it one of the lowest on the market. And FXAIX has delivered an average return of 15.68% over the last five years. There’s no minimum investment so it’s a great option for anyone who doesn’t have a lot of money to start investing with.

Schwab US Mid-Cap Index (SWMCX)

SWMCX attempts to replicate the returns of the Russell Midcap Index, and it measures mid-cap stocks. Industrials, financials and information technology are its top three sectors. It’s a low-cost fund and no minimum investment is required. Over the past five years, SWMCX earned an average annual return of 11.83%.

iShares Core S&P 500 ETF (IVV)

The iShares Core S&P 500 ETF is sponsored by BlackRock which is one of the largest fund companies. This fund has been around since 2000, and it’s a large-blend ETF tracking the S&P 500. It has a 0.03% expense ratio and delivered an average annual return of 15.65% over the last five years.

How To Invest in Index Funds

The first step to investing in index funds is to open and set up your brokerage account. Look for one that offers commission-free trading and many different investments to choose from.

From there, you can determine which index you want to track which will narrow your options once you start researching different funds. As you’re looking into different index funds consider:

  • Company size: You can invest in an index fund tracking large-, mid- or small-cap stocks. Small-cap stocks can generate higher returns but tend to be riskier than mid- and large-cap stocks. And large-cap stocks tend to be more stable but won’t have as much growth as small- or mid-cap stocks.
  • Location: You can choose a fund that tracks U.S.-based stocks, foreign exchanges or a combination of both.
  • Expense ratio: The expense ratio is the management fee, and you want this to be as low as possible. For example, if an index fund has an expense ratio of 0.04%, you’ll pay $40 per year for every $10,000 you’ve invested in the fund.
  • Minimum investment: It’s also important to consider whether or not the fund has a minimum investment, especially if you don’t have a lot of money to invest right away.

Once you’ve bought your index funds, you’ll continue to monitor them over time. Make sure the fund is closely mirroring the returns of the index it’s tracking. The returns won’t be identical since you are responsible for paying investment costs, but the performance shouldn’t lag by much more than the expense ratio.

Index Funds vs. Mutual Funds

Index funds and mutual funds play important roles in investing and can be good additions to your portfolio. A mutual fund uses public money from investors to maintain a portfolio of stocks, bonds or other market securities. Some mutual funds track an index, but they don’t all follow this strategy.

Understanding how index funds and mutual funds work will help you determine which is the best option for your situation. The table below outlines some of the key differences and who these funds are best for.
