Great for starters with low budget The ideal clients for Sharebuilder are investors without a lot of money. If you are just getting started with investing and only have $100 or so to invest each month, Sharebuilder is a consideration for you. You can create an automatic investing plan or use the ETF Portfolio Builder and call it a day.

Perfect for passive investors If you are looking to invest automatically (dollar-cost-average your investments) or want a cheap way to create a portfolio consisting of ETFs, then Capital One Investing is one of the best options available. The company is definitely leaning more towards passive investment style, therefore active investors or anyone looking for advanced tools, products or services from their brokerage should check out other online brokers.

Low costs for trading and no initial investment needed Capital One Investing has relatively low trading costs, doesn't require an initial investment and offers risk vs. reward tools. However, this online stock trading service is lacking important features and doesn't offer much in the way of educational resources.

Great choice for newbie traders Capital One Investing is clearly angled toward beginner investors, and it has the tools to help them build a solid base, along with low commissions and no account minimum. The brokerage’s automatic investment plan is a winner, and Capital One banking customers in particular will enjoy the administrative ease of putting all of their accounts under one roof. But advanced traders will want a larger investment selection and access to a trading platform.

Low fees plus automatic investing Use Capital One Investing as your standard online brokerage investment firm, but with the benefits of low fees and automatic investing.

Trading and research just got easier Capital One Investing is a great fit for investors seeking automatic investment plans, and customers of Capital One 360. It also offers casual investors an easy way to research and trade.
