Online Brokerage Comparison

Some brokers have minimum deposit requirements, while others may require a minimum balance to access certain advanced features or trading platforms.

If a broker is offering a new account promotion, there may be a minimum initial deposit requirement to qualify.

Like most things, when it comes to stock brokers, you often get what you pay for — which means there may be a trade off between price and quality.

Some brokers charge more per trade but offer access to a high-quality platform and premium research for free. Others have lower commissions, but offer fewer tools and services or charge to access certain tools.

If you're trading frequently — more than weekly — you'll want an advanced broker that has powerful platforms, innovative tools, high-quality research and low commissions.

Those who trade monthly or yearly will want a well-rounded broker with a user-friendly interface, helpful customer support and competitive pricing.

Yes, it's true — you don't have to manage your own investments. In fact, these days it's not only possible, but inexpensive to get the kind of management that was previously only available to investors with very high balances (read: mostly millionaires).

Thank the robo-advisor: These services use algorithms to build and manage investor portfolios. For a very low fee, they'll create a portfolio of ETFs based on your investing goals and risk tolerance, then rebalance it as needed. Many also offer tax-loss harvesting for taxable accounts.

If that sounds too hands-off for you and you want to manage your own investments, choose a self-directed account at an online broker.

Low Cost: Mutual fund and ETF investors want access to funds without commissions or transaction fees; stock or options traders want low commissions and no added fees for inactivity, tools or research.

Platform and tools: If you plan to trade frequently, you likely know what kind of tools you'll use most and what you want out of a platform.

User interface: Website and tools should be intuitive and easy to navigate.

Premium research: Investing, particularly frequent trading, requires analysis. The broker should provide extensive information to help you select the investments for your portfolio.

Promotions: This shouldn't be your primary concern, but it might be a tie breaker if you're stuck between two options.
