Why Invest in Fidelity Index Funds

Value—it's the Fidelity difference.

Fidelity index mutual funds offer some of the lowest prices in the industry.1 Plus, we offer 24/7 customer service online or by phone2 and were named Barron's 2016, 2017, and 2018 Best Online Broker3.

A wide range of choices

We offer index funds that attempt to track the performance of a range of the most widely followed equity and fixed income indexes. You'll find funds that seek to track U.S. stock market indexes of all market caps, as well as several international equity index funds, including an index fund dedicated to emerging markets. You'll also find bond index funds, including a fund that seeks to track the Bloomberg Barclays Indices. If you'd rather not build your own portfolio of index funds, you can buy a diversified portfolio containing a combination of four Fidelity stock and bond index funds.

Sustainable Index Funds

Fidelity's lineup also includes sustainable index funds: Fidelity U.S. Sustainability Index Fund (FITLX), Fidelity Sustainability Bond Index Fund (FNDSX) and Fidelity International Sustainability Index Fund (FNIDX). Learn more about socially responsible investing on our Investing Ideas section

Management experience

Fidelity has managed index funds for 30 years. We understand why you're buying index funds—you want an investment that performs as closely to its benchmark as possible. Over time we seek to minimize tracking error — the amount an index fund's performance deviates from its target index. Whether through solid trading techniques that completely replicate an index or our use of statistical sampling and optimization techniques when necessary, we are focused on tracking benchmark performance and delivering results our clients have come to expect.
