Is there a minimum stock price required for purchasing securities on margin?

IBKR does not directly use stock price as factor for determining margin requirements but does consider at a number of other factors including market capitalization which is a function of the stock price. Here, any security with a market capitalization of USD 250 million or below will be subject to a 100% margin requirement. In addition, we do not extend margin loans on securities based upon their listing, including Pink Sheet, OTC Bulletin Board and the Venture exchange.
