Quick Answer
Fidelity as a brokerage is neutral and usable for halal investing. Most of Fidelity's own mutual funds are NOT halal because they invest in broad market indices including banks, entertainment, and other non-compliant sectors. However, you can use Fidelity to buy halal ETFs and individual stocks.
Fidelity's Own Funds — Not Halal
Fidelity's flagship funds (Fidelity 500 Index Fund, Fidelity Total Market Index Fund, Fidelity Zero funds) track broad indices that include many non-compliant companies. These are not suitable for Muslim investors committed to Sharia compliance.
Fidelity as a Brokerage
Fidelity's brokerage platform is excellent for halal investing. You can buy any ETF including SPUS, HLAL, and UMMA through a Fidelity brokerage account. Fidelity's zero-commission trading, strong research tools, and excellent customer service make it a legitimate choice for Muslim investors — just choose your investments carefully.
Fidelity for Retirement Accounts
Fidelity administers millions of 401(k) plans and IRAs. If your employer's 401(k) is with Fidelity, your investment choices are limited to what your plan offers. Many Fidelity 401(k) plans don't include Islamic-screened options, but you may find a US equity growth fund that approximates halal exposure. For IRAs, you have full flexibility to invest in halal ETFs.
Bottom Line
Fidelity is a trustworthy brokerage platform. Most of Fidelity's own mutual funds are not halal, but the brokerage is perfectly usable for Muslim investors who choose their own halal investments.
