Index funds are mutual funds that seek only to mirror the performance of an underlying stock market index — not to outperform it. Millions of investors hold them in their portfolios because they provide an easy, one-and-done way to mitigate the risk that is inherent to stock picking. That’s because index funds allow investors to spread their money across dozens, hundreds or even thousands of companies instead of placing all-or-nothing bets on individual securities.

Understanding Index Funds
An index fund is a type of mutual fund that doesn’t require a fund manager to hand-pick securities and make decisions about how to spend the pooled money of many investors. With an index fund, the stocks are pre-selected to mirror a specific segment of the larger market. It’s called passive management, and it’s much more cost-effective because it eliminates the high fees and commissions that professional money managers command.
What Index Funds Are Ideal For
Is an Index Fund a Good Investment?
Index funds work by matching — or tracking — the performance of a stock market index.
An index is a group of stocks that share similar traits. For example, the S&P 500 index represents the 500 largest publicly traded U.S. companies. The Russell 2000, on the other hand, tracks the 2,000 smallest companies on the Russell 3000 index.
One investor might want the stability and familiarity of America’s biggest brand-name corporations. Another investor with a higher tolerance for risk might seek the greater growth potential of small companies that are still gaining traction.
In either case, both investors could gain broad exposure to all the stocks they want with the purchase of a single index fund.
How Index Funds Work
Index funds are passively managed, meaning they aim to replicate the performance of a specific market index, such as the S&P 500, rather than trying to outperform it. Fund managers allocate assets to mirror the index as closely as possible, buying the same stocks or bonds in the same proportions.
Comparing Index Funds to Actively Managed Funds
Unlike actively managed funds, which rely on frequent trading and research to beat the market, index funds focus on keeping costs low. They typically have lower fees and expense ratios, making them more affordable for investors. Additionally, their performance is consistent with the index they track, offering a reliable option for long-term growth.
When the fund’s underlying index performs well, so does the fund. Whether it’s biotech or mid-cap stocks, the fund will never do better or worse than the index as a whole. Over time, this is less risky than purchasing individual stocks, but it also limits short-term growth potential. One biotech stock, for example, could gain 20% in a single day, but that growth will be tempered by the performance of many other stocks in the fund — likewise, if it loses 20%.
Types of Index Funds
There are a few different types of index funds.
Stock Index Funds
Stock index funds track the performance of stock market indexes like the S&P 500 or the NASDAQ Composite. These funds provide exposure to a wide range of companies, making them ideal for investors seeking diversified growth in equities.
Bond Index Funds
Bond index funds focus on fixed-income securities and are often suited for conservative investors looking for stability and income. These funds can track indexes like the Bloomberg U.S. Aggregate Bond Index, offering a way to balance risk in a portfolio.
International Index Funds
International index funds provide exposure to global markets by tracking indexes that include companies outside your home country. They’re a great option for diversifying your investments across different economies and regions.
How to Invest in Index Funds
Steps to Get Started
Begin by setting clear financial goals, such as saving for retirement or building wealth over time. Choose a reliable brokerage or investment platform that offers a variety of index funds, and compare options based on expense ratios and past performance. Opt for funds that align with your goals and risk tolerance for the best results.
Automating Investments for Long-Term Success
Consider automating your investments with a strategy like dollar-cost averaging, where you invest a set amount regularly, regardless of market conditions. This approach helps smooth out market fluctuations and takes advantage of compounding over time, making it easier to stay consistent and build wealth gradually.
Who Should Invest in Index Funds?
Index funds are a relatively inexpensive and moderate-risk way to invest. They bring returns equal to, but not greater than, the sector or market they track. Index funds can be a good investment for certain investors.

Now Might Be a Good Time to Buy an Index Fund
The “best time” to make any investment depends on your goals, strategy and financial situation — but the current bear market presents a unique opportunity. Analysts disagree on whether the market has hit its bottom, but many stocks — and therefore many index funds — are “on sale,” and trading well off their previous highs. That gives investors a chance to buy low and have their money in play when the inevitable recovery sets in and values start to rise once more.
