Penny stocks are considered highly speculative (and high risk) investments due to their lack of liquidity, large bid-ask spreads, small capitalization and limited filing and regulatory standards. Still, some investors like to trade penny stocks because the low price makes it possible to hold thousands of shares for a relatively small amount of capital – and all those shares mean investors can profit with the gain of just a few cents per share.

While many brokers offer penny stocks, some add a surcharge to stocks that trade below a certain dollar level or volume restrictions that bump up the price for large orders. We selected these five brokers as the best for penny stocks:

  • Interactive Brokers
  • TradeStation
  • eOption
  • Fidelity Investments
  • Charles Schwab

Low-priced securities cannot be held in custody at the Depository Trust Company (DTC) and, may carry pass-through charges that can be as high as 10 times the value of the trade itself. Non-DTC eligible securities cannot be cleared electronically. Exchanges such as NYSE and Nasdaq require DTC-eligibility, but it’s up to you to determine the eligibility of penny stocks trading on the OTC Bulletin Board and OTC Markets Group (a current list can be found on the DTCC website).

Our criteria for putting a broker on this list includes access to the OTC markets, low account minimums, flat rate per-trade commissions with no additional charge for low-cost stocks. We also look for real-time margin calculations so you're aware of your buying power.

Lightspeed charges a flat $10 per OTCBB transaction, which is much higher than average.

Investopedia’s mission is to provide investors with unbiased, comprehensive reviews and ratings of online brokers. Our reviews are the result of six months of evaluating all aspects of an online broker’s platform, including the user experience, the quality of trade executions, the products available on their platforms, costs and fees, security, the mobile experience and customer service. We established a rating scale based on our criteria, collecting over 3,000 data points that we weighed into our star scoring system.

In addition, every broker we surveyed was required to fill out a 320-point survey about all aspects of their platform that we used in our testing. Many of the online brokers we evaluated provided us with in-person demonstrations of their platforms at our offices.

Our team of industry experts, led by Theresa W. Carey, conducted our reviews and developed this best-in-industry methodology for ranking online investing platforms for users at all levels. Click here to read our full methodology.
