Fidelity is the all-rounder for most long-term investors. A Fidelity brokerage account has no minimum and no account fees, charges nothing to trade US stocks and ETFs online, lets you buy slices of a share from $1 and offers Fidelity's own mutual funds at $0.
- +No minimum, no commissions on stocks and ETFs, and $0 Fidelity funds
- +Seven retirement account types with no annual IRA fee
- −Receives payment for order flow in its latest order-routing report
