Penny stocks are risky, low-cost investments, though they don’t actually cost a penny. They are shares of small companies that trade outside of major stock exchanges and are also known as over-the-counter (OTC) stocks.

The precise definition of penny stocks will vary by broker. Some consider anything trading under $5 a penny stock, while others set the cutoff at $2 or $1.

Penny stocks may seem like a steal when stacked against companies that trade for $500 or more. This is where the backstory is important: These stocks are cheap for a reason. Because they are issued by small, yet-to-be-established companies, their value can be turbulent. They are often hard to research and accurately appraise, and they trade infrequently, making them tough to sell.

Long story short, many brokers are a bit antsy about trading penny stocks. This can make it more challenging to figure out where to buy penny stocks than with other investments.

Below are NerdWallet’s picks for the top brokerages for penny stock traders. These four brokers don't impose any additional fees or investment restrictions on domestic penny stocks.

Best penny stock brokers overview


SoFi Active Investing is a great choice for OTC stock traders, as it offers no-commission trades and puts no investment restrictions on penny stocks. However, traders who want access to exotic assets such as forex and crypto — or who want third-party research to inform their trading decisions — may need to look elsewhere.

Robinhood offers free ETF, options, crypto and stock trades (including all OTC stocks). It's also a leader in mobile-first design for brokerage apps, and provides a streamlined trading interface. However, Robinhood doesn't offer much in the way of third-party research, and its execution quality is slightly below average.

Moomoo users can trade U.S.-listed ETFs, equity options and stocks (including OTC stocks) without any fees, in an easy-to-use app with low margin rates. However, Moomoo's execution quality could be better, and it does charge a commission of a few pennies per share on foreign-listed stock trades.

Merrill Edge is a great choice for penny stock traders who have a Bank of America account, as it's integrated into Bank of America's app, and offers free trades of all OTC stocks with high order execution quality. However, fractional shares and alternative assets such as crypto and futures, which may also appeal to penny stock traders, are not available.

Choosing a penny stockbroker


In case the above didn’t make this clear: There are significant risks that come with trading penny stocks, unless you are a sophisticated investor and you understand this market. You'll also want to be aware of the following when selecting an online broker to trade penny stocks:

Additional fees: Most of the brokers we review have eliminated trading commissions for stocks, provided those stocks are well-established and trade on major U.S. exchanges such as the NYSE and Nasdaq. But many brokers still charge some kind of trading fee for OTC stocks and foreign stocks that aren't officially listed on U.S. exchanges. Only a few brokers are commission-free for penny stock traders, but we've made our list exclusive to brokers that don't charge commissions.

Limited penny stock selection: Some brokers only offer a small selection of relatively-established OTC stocks to investors, and others only offer one-off penny stock trades on request. If you're looking to trade especially obscure penny stocks, you may find that many brokers don't allow access to them.

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).

This list is based on our OTC access score, which measures the size of a broker's OTC stock selection, whether OTC stocks are subject to additional fees, and whether OTC trades are available by default or have to be requested. Merrill Edge, Moomoo, SoFi Active Investing and Robinhood are the only brokers we review that earned the highest possible score in this category, meaning that they offer an unlimited selection of domestic OTC stocks to all users without any additional fees.
