According to FINRA REGULATIONS only the stocks above $2.00 can be used as margin collateral. Then only the value of the stock over the $2.00 threshold can be added to the margin pool. As example a $3.00 would allow $1 for margin pool.
Similarly cash requirements for accounts less than $25 million in value to short a stock one needs to hold cash of $2.50 per share short sold even if $0.01 or less. So if you suspect your penny stock is being shorted then it shorted by accounts valued at $25 million or more. The big money rules the roost and can manipulate stock prices with impunity. The system is designed in my opinion to favor big accounts and cripple small ones to allow big accounts to crush retail that dares to trade instead of long term investment.
