What is Margin Trading (Buying)?
Margin buying is buying securities with some of one’s own cash together with cash borrowed from a broker. This has the effect of magnifying any profit or loss made on the securities. The securities serve as collateral for the loan. The net value, i.e. the difference between the value of the securities and the loan, is initially equal to the own cash used. This difference has to stay above a minimum margin requirement. This is to protect the broker against a fall in the value of the securities to the point that they no longer cover the loan.
