Well that cannot be, because it was stated : Most brokers won't let you buy stocks under $5 on margin. Most brokers won't let you buy ANY OTC stock on margin regardless of the price. Strongly asserted As if buying on margin isn't possible for under $5 or ANY OTC stock. How is one to initially borrow the security if not on margin considering the statement above???? I recommend reading Reg T and familiarity with FINRA Rule 4210
