Here’s everything you need to know about index funds and ten of the top index funds to consider adding to your portfolio this year.

Last updated on January 29, 2023, and last reviewed by an expert on January 14, 2022.

Index funds are popular with investors because they promise ownership of a wide variety of stocks, greater diversification and lower risk – usually all at a low cost. That’s why many investors, especially beginners, find index funds to be superior investments to individual stocks.

Some of the most watched indexes fill up the financial news every night, whether it’s the Standard & Poor’s 500 (S&P 500), the Nasdaq Composite, or the Dow Jones Industrial Average. These indexes are often shorthand for the performance of the market, and investors track them to get a read on how stocks as a whole are faring.

Here’s everything you need to know about index funds, including ten of the top index funds to consider adding to your portfolio this year.

Best index funds for 2022

The list below includes index funds from a variety of companies tracking a variety of broadly diversified indexes and it includes some of the lowest-cost funds trading on the public markets. When it comes to index funds like these, one of the most important factors in your total return is cost. Included are three mutual funds and seven ETFs:

1. Fidelity ZERO Large Cap Index (FNILX)

The Fidelity ZERO Large Cap Index mutual fund is part of the investment company’s foray into mutual funds with no expense ratio, thus its ZERO moniker. The fund doesn’t officially track the S&P 500 – technically it follows the Fidelity U.S. Large Cap Index – but the difference is academic. The real difference is that investor-friendly Fidelity doesn’t have to cough up a licensing fee to use the S&P name, keeping costs lower for investors.

Expense ratio: 0 percent. That means every $10,000 invested would cost $0 annually.

2. Shelton NASDAQ-100 Index Direct (NASDX)

The Shelton Nasdaq-100 Index Direct ETF tracks the performance of the largest non-financial companies in the Nasdaq-100 Index, which includes primarily tech companies. This mutual fund began trading in 2000 and has a strong record over the last five and ten years.

Expense ratio: 0.5 percent. That means every $10,000 invested would cost $50 annually.

3. Invesco QQQ Trust ETF (QQQ)

The Invesco QQQ Trust ETF is another index fund that tracks the performance of the largest non-financial companies in the Nasdaq-100 Index. This ETF started trading in 1999, and it’s managed by Invesco, a fund giant. This fund is the top-performing large-cap fund in terms of total return over the 15 years to Sept. 2021, according to Lipper.

Expense ratio: 0.2 percent. That means every $10,000 invested would cost $20 annually.

4. Vanguard S&P 500 ETF (VOO)

As its name suggests, the Vanguard S&P 500 tracks the S&P 500 index, and it’s one of the largest funds on the market with hundreds of billions in the fund. This ETF began trading in 2010, and it’s backed by Vanguard, one of the powerhouses of the fund industry.

Expense ratio: 0.03 percent. That means every $10,000 invested would cost $3 annually.

The SPDR S&P 500 ETF is the granddaddy of ETFs, having been founded all the way back in 1993. It helped kick off the wave of ETF investing that has become so popular today. With hundreds of billions in the fund, it’s among the most popular ETFs. The fund is sponsored by State Street Global Advisors — another heavyweight in the industry — and it tracks the S&P 500.

Expense ratio: 0.09 percent. That means every $10,000 invested would cost $9 annually.

The Vanguard Russell 2000 ETF tracks the Russell 2000 Index, a collection of about 2,000 of the smallest publicly traded companies in the U.S. This ETF began trading in 2010, and it’s a Vanguard fund, so it focuses on keeping costs low for investors.

Expense ratio: 0.10 percent. That means every $10,000 invested would cost $10 annually.

7. iShares Core S&P 500 ETF (IVV)

The iShares Core S&P 500 ETF is a fund sponsored by one of the largest fund companies, BlackRock. This iShares fund is one of the largest ETFs and it tracks the S&P 500. With an inception date of 2000, this fund is another long-tenured player that’s tracked the index closely over time.

Expense ratio: 0.03 percent. That means every $10,000 invested would cost $3 annually.

8. Schwab S&P 500 Index Fund (SWPPX)

With tens of billions in assets, the Schwab S&P 500 Index Fund is on the smaller side of the heavyweights on this list, but that’s not really a concern for investors. This mutual fund has a strong record dating back to 1997, and it’s sponsored by Charles Schwab, one of the most respected names in the industry. Schwab is especially noted for its focus on making investor-friendly products, as evidenced by this fund’s razor-thin expense ratio.

Expense ratio: 0.02 percent. That means every $10,000 invested would cost $2 annually.

9. Vanguard Total Stock Market ETF (VTI)

Vanguard also offers a fund that covers effectively the entire universe of publicly traded stocks in the U.S., known as the Vanguard Total Stock Market ETF. It consists of small, medium and large companies across all sectors. The fund has been around for a while, having begun trading in 2001. And with Vanguard as the sponsor, you know the costs are going to be low.

Expense ratio: 0.03 percent. That means every $10,000 invested would cost $3 annually.

10. SPDR Dow Jones Industrial Average ETF Trust (DIA)

You don’t have a lot of choice when it comes to ETFs tracking the Dow Jones Industrial Average, but State Street Global Advisors comes through with this fund that tracks the 30-stock index of large-cap stocks. The fund is definitely one of the earlier ETFs, having debuted in 1998, and it has tens of billions under management.

Expense ratio: 0.16 percent. That means every $10,000 invested would cost $16 annually.

Index funds based on major indexes are popular for many reasons. These funds offer a good return over time, they’re diversified and a relatively low-risk way to invest in stocks.

While some funds such as S&P 500 or Nasdaq-100 index funds allow you to own companies across industries, other funds own only a specific industry, country or even investing style (say, dividend stocks).

How to invest in an index fund in 3 easy steps

It’s surprisingly easy to invest in an index fund, but you’ll want to know what you’re investing in, not simply buy random funds that you know little about.

1. Research and analyze index funds

Your first step is finding what you want to invest in. While an S&P 500 index fund is the most popular index fund, they also exist for different industries, countries and even investment styles. So you need to consider what exactly you want to invest in and why it might hold opportunity:

You’ll want to carefully examine what the fund is investing in, so you have some idea of what you actually own. Sometimes the labels on an index fund can be misleading. But you can check the index’s holdings to see exactly what’s in the fund.

2. Decide which index fund to buy

After you’ve found a fund you like, you can look at other factors that may make it a good fit for your portfolio. The fund’s expenses are huge factors that could make – or cost – you tens of thousands of dollars over time.

3. Purchase your index fund

After you’ve decided which fund fits in your portfolio, it’s time for the easy part – actually buying the fund. You can either buy directly from the mutual fund company or through a broker. But it’s usually easier to buy a mutual fund through a broker. And if you’re buying an ETF, you’ll need to go through your broker.

Things to consider when investing in index funds

As you’re looking at index funds, you’ll want to consider the following factors:

Can an index fund investor lose everything?

Putting money into any market-based investment such as stocks or bonds means that investors could lose it all if the company or government issuing the security runs into severe trouble. However, the situation is a bit different for index funds because they’re often so diversified.

Suggested read: Active investing vs. passive investing: What’s the difference?

An index fund usually owns at least dozens of securities and may own potentially hundreds of them, meaning that it’s highly diversified. In the case of a stock index fund, for example, every stock would have to go to zero for the index fund, and thus the investor, to lose everything. So while it’s theoretically possible to lose everything, it doesn’t happen for standard funds.

That said, an index fund could underperform and lose money for years, depending on what it’s invested in. But the odds that an index fund loses everything are very low.

What is considered a good expense ratio?

Mutual funds and ETFs have among the cheapest average expense ratios, and the figure also depends on whether they’re investing in bonds or stocks. In 2020, the average stock index mutual fund charged 0.06 percent (on an asset-weighted basis), or $6 for every $10,000 invested. The average stock index ETF charged 0.18 percent (asset-weighted), or $18 for every $10,000 invested.

Index funds tend to be much cheaper than average funds. Compare the numbers above with the average stock mutual fund (on an asset-weighted basis), which charged 0.54 percent, or the average stock ETF, which charged 0.18 percent. While the ETF expense ratio is the same in each case, the cost for mutual funds generally is higher. Many mutual funds are not index funds, and they charge higher fees to pay the higher expenses of their investment management teams.

So anything below the average should be considered a good expense ratio. But it’s important to keep these costs in perspective and realize that the difference between an expense ratio of 0.10 percent and 0.05 percent is just $5 per year for every $10,000 invested. Still, there’s no reason to pay more for an index fund tracking the same index.

Is now a good time to buy index funds?

If you’re buying a stock index fund or almost any broadly diversified stock fund such as the Nasdaq-100, it can be a good time to buy if you’re prepared to hold it for the long term. That’s because the market tends to rise over time, as the economy grows and corporate profits increase. In this regard, time is your best friend, because it allows you to compound your money, letting your money make money. That said, narrowly diversified index funds (such as funds focused on one industry) may do poorly for years.

That’s one reason why it’s crucial for investors to stick with a patient approach to ride out any short-term volatility. Experts recommend adding money to the market regularly to take advantage of dollar-cost averaging and lower their risk. A strong investing discipline can help you make money in the market over time. Investors should avoid timing the market, that is, jumping in and out of the market to capture gains and dodge losses.

Index fund FAQ:

If you’re looking to get into index funds, you may still have a few more questions. Here are answers to some of the most frequently asked questions that investors have about them.

How do index funds work?

An index fund is an investment fund – either a mutual fund or an exchange-traded fund (ETF) – that is based on a preset basket of stocks, or index. This index may be created by the fund manager itself or by another company such as an investment bank or a brokerage.

Suggested read: What are mutual funds?

These fund managers then mimic the index, creating a fund that looks as much as possible like the index, without actively managing the fund. Over time the index changes, as companies are added and removed, and the fund manager mechanically replicates those changes in the fund.

Because of this approach, index funds are considered a type of passive investing, rather than active investing where a fund manager analyzes stocks and tries to pick the best performers.

This passive approach means that index funds tend to have low expense ratios, keeping them cheap for investors getting into the market.

Suggested read: Stocks vs. mutual funds: Which should you invest in?

Some of the most well-known indexes include the S&P 500, the Dow Jones Industrial Average and the Nasdaq-100. Indexing is a popular strategy for ETFs to use, and most ETFs are based on indexes.

What sort of fees are associated with index funds?

Index funds may have a couple different kinds of fees associated with them, depending on which type of index fund:

Mutual funds

Index funds sponsored by mutual fund companies may charge two kinds of fees: a sales load and an expense ratio.

ETFs

Index funds sponsored by ETF companies (many of which also run mutual funds) charge only one kind of fee, an expense ratio. It works the same way as it would with a mutual fund, with a tiny portion seamlessly deducted each day you hold the fund.

Suggested read: What is the S&P 500?

ETFs have become more popular recently because they help investors avoid some of the higher fees associated with mutual funds. ETFs are also becoming popular because they offer other key advantages over mutual funds.

The bottom line

These are some of the best index funds on the market, offering investors a way to own a broad collection of stocks at low cost, while still enjoying the benefits of diversification and lower risk. With those benefits, it’s no surprise that these are some of the largest funds on the market.
