This document discusses margin funding, which provides short-term loans to investors to help ease cash flow issues and allow continued trading. Margin funding requires investors to put up only a portion of the investment amount, usually 50%, with the broker providing the rest as a loan. The loan has an interest rate typically between 15-18% charged by the broker. If the value of shares purchased with margin funding drops significantly, the investor may face a margin call requiring them to deposit more funds or risk having their position liquidated by the broker.
