If a customer chooses to borrow funds from a firm, the customer will open a margin account with that firm. The portion of the purchase price that the customer must deposit is called margin and is the customer's initial equity in the account. The loan from the firm is secured by the securities that are purchased by the customer. Customers generally use margin to leverage their investments and increase their purchasing power. At the same time, customers who trade securities on margin incur the potential for higher losses; therefore, customers should make sure they clearly understand this concept before opening a margin account and entering the investing arena.
