Methodology
NerdWallet’s comprehensive review process evaluates and ranks the largest U.S. brokers by assets under management, along with emerging industry players. Our aim is to provide an independent assessment of providers to help arm you with information to make sound, informed judgements on which ones will best meet your needs. We adhere to strict guidelines for editorial integrity.
We collect data directly from providers through detailed questionnaires, and conduct first-hand testing and observation through provider demonstrations. The questionnaire answers, combined with demonstrations, interviews of personnel at the providers and our specialists’ hands-on research, fuel our proprietary assessment process that scores each provider’s performance across more than 20 factors. The final output produces star ratings from poor (one star) to excellent (five stars). Ratings are rounded to the nearest half-star.

NerdWallet's Best Online Brokers for Stock Trading of July 2022
Frequently asked questions
Not much. Note that many of the brokers above have no account minimums for both taxable brokerage accounts and IRAs. Once you open an account, all it takes to get started is enough money to cover the cost of a single share of a stock and the trading commission, if charged. (See “How to Buy Stocks” for step-by-step instructions on placing that first trade.)
Trading costs definitely matter to active and high-volume traders, but many brokers now offer commission-free trades of stocks and ETFs. Other factors — access to a range of investments or training tools — may be more valuable than saving a few bucks when you purchase shares.
One easy way is to invest in exchange-traded funds. ETFs are essentially mutual funds that are bought and sold just like individual stocks on a stock market exchange. Like mutual funds, each ETF contains a basket of stocks (sometimes hundreds) that adhere to particular criteria (e.g., shares of companies that are part of a stock market index like the S&P 500). Unlike mutual funds, which can have high investment minimums, investors can purchase as little as one share of an ETF at a time.
Your money is indeed insured, but only against the unlikely event a brokerage firm or investment company goes under. A broker’s SIPC coverage (Securities Investor Protection Corporation) doesn't cover any loss in value of your investments.
Your account choices boil down to a taxable brokerage account versus tax-favored retirement account, such as an IRA. Our guide to brokerage accounts goes into more detail about what’s involved in setting up a taxable account. Opening an IRA involves choosing which type, such as a Roth IRA, traditional IRA or SEP IRA. If you're new to this, we’ve got you covered in our guide to IRAs.
After you’ve opened the account, you’ll need to initiate a deposit or funds transfer to the brokerage firm, which can take anywhere from a few days to a week. Once that is complete, it’s off to the investing races! And by that we mean taking a thoughtful and disciplined approach to investing your money for the long-term.
Some key criteria to consider when evaluating any investment company are how much money you have, what type of assets you intend to buy, your trading style and technical needs, how frequently you plan to transact and how much service you need. Our post about how to choose the best broker for you can help you sort through the features brokerage firms offer and rank your priorities.
