The Margin is the money borrowed from a brokerage firm to purchase an investment.
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 buy securities.
The practice includes buying 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.
