A margin account is a brokerage account in which the broker lends the customer cash to purchase stocks or other financial products. The loan in the account is collateralized by the securities purchased and cash, and comes with a periodic interest rate. Because the customer is investing with borrowed money, the customer is using leverage which will magnify profits and losses for the customer. If an investor purchases securities with margin funds, and those securities appreciate in value beyond the interest rate charged on the funds, the investor will earn a better total return than if they had only purchased securities with their own cash. This is the advantage of using margin If, at any time during the term of a Contract, the Actual Margin is less than the Required Margin, the shortfall is immediately due and payable, and, if not paid, constitutes an Event of Default. If, at any time during the term of a Contract, the Actual Margin is not sufficient to cover the Required Margin, you must Close Out Open Positions or transfer adequate funds to us. Actual Margin: Client’s funds divided by the total market value of the client’s portfolio.
