How To Invest In Vanguard Index Funds (2024)

Investing in index funds is a great way to diversify your portfolio and reduce fees to a minimum. Vanguard index funds are a popular option: There are more than 60 Vanguard index mutual funds that track a wide variety of domestic and international stock and bond indexes. Here’s what you need to know about Vanguard index funds and how to choose the right fund for your portfolio.

What Are Vanguard Index Funds?

When you buy shares of a Vanguard index fund, your money is invested in a diversified portfolio of assets that track an underlying market index. Vanguard founder Jack Bogle invented the index fund when it launched the Vanguard 500 (VFINX) in 1976.

With over 40 years of experience, Vanguard’s funds have delivered consistent long-term returns—according to the company, 84% of its index funds have performed better than their peer-group averages over the past decade.

An index fund is a type of mutual fund that aims to match the performance of a specific market benchmark or index as closely as possible, such as the S&P 500, an equity index tracks 500 of the leading publicly held U.S. companies. Other major indexes include the Dow Jones Industrial Average (DJIA), the Nasdaq Composite and the Wilshire 5000.

There are indexes for nearly every market and every asset class. Vanguard index funds buy all of the stocksor bonds—or a representative sample—that are included in the index it aims to track.

There is always a level of risk involved with Vanguard index funds: Risk corresponds to the stock or bond market the index fund tracks. For example, a Vanguard index fund that tracks stocks will generally be riskier than one that tracks investment-grade bonds.

How Do Vanguard Index Funds Work?

When you invest in a Vanguard index fund, you’re investing in hundreds or even thousands of securities at once. If some securities perform poorly, the other investments held by the Vanguard index fund can help mitigate the risk, protecting your investment. Index funds provide instant diversification and low costs, without having to put in a ton of work yourself.

Vanguard index funds are professionally managed; you can buy or sell mutual funds over the phone, and you can set up automatic investments or withdrawals.

As of May 31, 2020, Vanguard offers 62 index mutual funds, including funds in the following categories:

• U.S. bond funds: Adding bonds funds to your portfolio can help balance the risks associated with any stock funds you may hold. Vanguard U.S. bond funds invest in U.S. corporate bonds, U.S. Treasurysand Treasury-backed securities.
• U.S stock funds: Vanguard U.S. stock funds invest in domestic companies, including large-cap, mid-cap and small-cap companies.
• Balanced funds: Balanced funds invest in a mix of stocks and bonds to provide a balance of income and growth. Target-date funds, a popular choice for retirement investors, are included in this group.
• International stock funds: Vanguard international stock funds invest in companies based outside of the U.S.
• International bond funds:International bond funds add diversification and invest in both government and corporate bonds issued outside the U.S.
• Sector and specialty funds: If you have a particular interest in a certain industry and are comfortable with additional volatility, you may be interested in sector and specialty funds. You can invest in specific industries, such as energy, health care and real estate.

Vanguard Index Fund Costs and Fees

Vanguard index funds can be very cost-effective investments: As of Dec. 31, 2019, Vanguard’s average mutual fund expense ratio was 0.10%. With a no-load mutual fund—meaning there are no sales fees when you buy fund shares or when you sell fund shares—you don’t have to worry about paying commissions, either.

However, you do need to have some money saved before you can start investing. According to the company, 43 of Vanguard’s index funds are available at the Admiral Shares level, meaning there is a $3,000 minimum investment requirement.

Pick an index

When it comes to index mutual funds, it’s important to pick the right index for your needs. There are literally hundreds to choose from. You can pick an index based on industry, company size, location or asset type.

If you’re overwhelmed by the options, consider choosing a target-date fund, balanced-fund or a broad-market index that tracks the performance of a large segment of the stock market to get started.

Check costs

Index mutual funds tend to have lower costs than other investment options, making them the right choice for long-term investing. However, there are still costs you should consider, including expense ratios and fees.

The expense ratio is how much of the fund’s assets go toward administrative and operational expenses, cutting into your returns.According to Vanguard, the average expense ratio across its index mutual funds is 73% less than industry average.

Vanguard may charge purchase and redemption fees to buy or sell shares of its funds. Many of the company’s funds are free of such fees, but a select few charge 0.25% to 1.00% for purchases and redemptions.
