No, they don't. None of the brokers let you short penny stocks. There is a reason. There is NOTHING IN IT FOR THEM. Any brokerage that permits shorting of stocks also requires a cash deposit, called a margin loan. Most of the time it is on the order of $2.50 per share. Shorting penny stocks with that much up front money to make less than a fraction of a penny per share simply makes no sense, for either the trader OR the brokerage.
If you don't believe that, TRY IT. Short 100 shares of any penny stock. You CAN'T. Not one person in over 10 years has ever come back and proven that they could short a penny stock. That's because you can't.
