Margin: A term generally used in the field of investment to describe a type of stock trading system. A system whereby a client first places an initial cash deposit with the broker to pay a part of his intending purchase or as part security for a short sale. He will then borrow the rest of the purchase or sales cost from the broker. The amount which he borrows from the broker is known as the Margin Debt or simply the Margin. The amount he can borrow is a fixed percentage of the market value of the security (normally 50 per cent). In the event of a fall in the price of the stock such that 50 per cent of the market value of the stock is smaller than the amount of margin debt outstanding, the broker can ask the client for additional injections of funds to cover the shortfall. This is known as a Margin Call.
