Margin is the money borrowed from a brokerage to execute a trade. It is the difference between the total value of securities held in an investor's account and the loan amount from the broker. Buying on margin is the act of borrowing money to trade securities. The practice includes trading an asset where the buyer pays only a percentage of the asset's value and borrows the rest from the bank or broker. The broker acts as a lender and the securities in the investor's account act as collateral.

 

An Example of Margin


Let's say that you deposit R10,000 in your margin account. Because you put up 50% of the purchase price, this means you have R20,000 worth of buying power. Then, if you buy R5,000 worth of stock, you still have R15,000 in buying power remaining. You have enough cash to cover this transaction and haven't tapped into your margin. You start borrowing the money only when you trade securities worth more than R10,000. 

Note that the buying power of a margin account changes daily depending on the price movement of the marginable securities in the account.
