If you're interested in opening an investment account with Fidelity, you can choose to invest through its website, the Active Trader Pro desktop platform, or Fidelity's mobile apps. In addition to a traditional brokerage account where you choose your investments, Fidelity also offers robo-advisor and investment advisor services to those that prefer having others help manage their portfolios. Fidelity Investments could be a good choice for beginners due to its vast educational materials, no account minimums (for certain accounts), low-cost investment options, and a wide variety of account types.
