Introduction – Fidelity Index Funds

Fidelity is one of the oldest and largest brokerage firms out there, closely rivaling and in some cases even beating Vanguard and Schwab on things like fees, fractional shares, margin rates, etc.

Fidelity has made a concerted effort of lowering its fees on its broad index funds in recent years, which in some instances are now the cheapest game in town, such as with their small line of ZERO funds with zero fees. Their mutual funds also have no minimum investment requirement, unlike Vanguard.

Note that so far Fidelity has kept its broad stock market index offerings (e.g. S&P 500, total U.S. stock market, etc.) as mutual funds; they don't have ETFs available for these yet. So all the funds on this list are mutual funds. They do have some very affordable sector ETFs that I covered in a separate post here.

Where applicable, I've included the comparable ZERO fund, but just remember I detailed here how you cannot buy or transfer those outside of Fidelity, so keep that in mind.

Let's dive into the best Fidelity index funds.

FXAIX – Fidelity 500 Index Fund

FXAIX is Fidelity's offering for the famous S&P 500 Index, roughly the 500 largest profitable publicly traded companies in the United States. As such, this fund is entirely U.S. large cap stocks, though it's considered a sufficient proxy for the entire U.S. stock market. This fund has about 500 holdings and an expense ratio of 0.015%.

The comparable Fidelity ZERO fund for this market segment is FNILX.

FSKAX – Fidelity Total Market Index Fund

FSKAX goes a bit further and includes small and mid caps within the U.S., thereby capturing the entire U.S. stock market via the Dow Jones U.S. Total Stock Market Index. This fund has about 4,000 holdings and an expense ratio of 0.015%.

The comparable Fidelity ZERO fund for this market segment is FZROX.

FSGGX – Fidelity Global ex US Index Fund

FSGGX allows investors to get international exposure to the global stock market outside the U.S. by tracking the MSCI ACWI ex USA Index. This fund has about 2,400 holdings and a fee of 0.055%.

The comparable Fidelity ZERO fund for this market segment is FZILX.

FISVX – Fidelity Small Cap Value Index Fund

Many investors, myself included, like to overweight small cap value stocks relative to their market cap weight for greater expected returns. Fidelity's index fund for this market segment is FISVX, which seeks to track the Russell 2000 Value Index. This fund has about 1,400 holdings and a fee of 0.05%.

FXNAX – Fidelity U.S. Bond Index Fund

FXNAX is an index fund for the total U.S. bond market for those wanting some asset class diversification outside stocks. This fund has an effective intermediate duration of about 6 years and seeks to track the Bloomberg U.S. Aggregate Bond Index. FXNAX has a fee of 0.025%.
