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.

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 include access to the OTC markets, low account minimums, $0 or 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.

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. Many brokers are charging commissions for trading penny stocks in spite of cutting commissions to $0 on exchange-traded stocks and ETFs.
