after opening and funding an account.

Why we like it

Webull will appeal to the mobile-first generation of casual investors with its slick interface for desktop and mobile apps, but the brokerage also delivers an impressive array of tools for active traders. However, its relatively weak educational content may leave true beginners in the lurch, and it lacks access to a few common asset classes.

Pros

  • Low costs.

  • Easy-to-use platform.

  • Advanced tools.

  • Access to cryptocurrency.

Cons

  • No mutual funds.

  • Thin educational support.

Why we like it

Robinhood provides free stock, options, ETF and cryptocurrency trades, and its account minimum is $0, too. Mutual funds and bonds aren't offered, and only taxable investment accounts are available. Still, if you're looking to limit costs or trade crypto, Robinhood is a solid choice.

Methodology

NerdWallet’s comprehensive review process evaluates and ranks the largest U.S. brokers and robo-advisors by assets under management, along with emerging industry players, using a multifaceted and iterative approach. Our aim is to provide an independent assessment of providers to help arm you with information to make sound, informed judgments on which ones will best meet your needs.

DATA COLLECTION AND REVIEW PROCESS

We collect data directly from providers, and conduct first-hand testing and observation through provider demonstrations. Our process starts by sending detailed questionnaires to providers to complete. The questionnaires are structured to equally elicit both favorable and unfavorable responses from providers. They are not designed or prepared to produce any predetermined results. The questionnaire answers, combined with product 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.

RATING FACTORS

Evaluations vary by provider type, but in each case are based upon the weighted averages of factors that include but are not limited to: advisory and account fees, account minimums and types, investment selection, investment expense ratios, trading costs, access to human financial advisors, educational resources and tools, rebalancing and tax minimization options, and customer support including branch access, user-facing technology and mobile platforms.

Each factor can involve evaluating various sub-factors. For instance, when gauging the investment selections offered by robo-advisors, 80% of the score is based on the potential for diversification (how well-diversified a resulting portfolio of investments could be) combined with the availability of specialty portfolios and level of customization for investors. Expense ratios form an additional 10% of the score, and low or no management fee the remaining 10%.

FACTOR WEIGHTINGS

The weighting of each factor is based on our team’s assessment of which features are the most important to consumers and which ones impact the consumer experience in the most meaningful way. The factors considered, and how those factors are weighted, change depending upon the category of providers reviewed.

Provider categories include: Best Brokers for Stock Trading, Best Brokers for Beginners, Best Brokers for Day Trading, Best Brokers for Options Trading, Best Discount Brokers, Best Brokers for Free Trading, Best Investment Apps, Best Brokers for Penny Stocks, Best IRA Brokers, Best Robo-Advisors, Best Financial Advisors, Best Real Estate Platforms, Best Brokers for ETFs and Best Brokers for Mutual Funds.

INFORMATION UPDATES

Writers and editors conduct our broker and robo-advisor reviews on an annual basis but continually make updates throughout the year. We maintain frequent contact with providers and highlight any changes in offerings.

THE REVIEW TEAM

The review team comprises seasoned writers, researchers and editors who cover stocks, bonds, mutual funds, index funds, exchange-traded funds, alternative investments, socially responsible investing, financial advisors, retirement and investment strategy on a daily basis. In addition to NerdWallet, the work of our team members has been published in The New York Times, The Washington Post, Forbes, USA Today, Bloomberg News, Nasdaq, MSN, MarketWatch, Yahoo! Finance and other national and regional media outlets.

The combined expertise of our Investing team is infused into our review process to ensure thoughtful evaluations of provider products and services from the customer perspective. Our writers and editors combine to have more than 70 years of deep experience in finance, ranging from a former Wall Street Journal reporter to a former senior financial advisor at Merrill Lynch.

CONFLICTS OF INTEREST

While NerdWallet does have partnerships with many of the reviewed providers, we manage potential conflicts of interest by maintaining a wall between our content and business operations. This wall is designed to prevent our writers and the review process from being influenced or impacted by our business partnerships. This way, all reviews can provide an unbiased review that serves the interests of our users. For more information, see NerdWallet’s editorial guidelines.
