Tak, słowo "deferred" nie pojawia się w "buying on margin", bo to zakup za pożyczone pieniądze/na depozyt/pod kaucję zabezpieczającą.
Buying on margin is the purchase of an asset
by paying the margin and borrowing the balance from a bank or broker.--
In finance,
a margin is collateral that the holder of a financial instrument has to deposit to cover some or all of the credit risk of their counterparty (most often their broker or an exchange). This risk can arise if the holder has done any of the following:
- Borrowed cash from the counterparty to buy financial instruments,
- Sold financial instruments short, or
- Entered into a derivative contract.
The collateral can be in the form of cash or securities, and it is deposited in a margin account. On United States futures exchanges, margins were formerly called performance bonds. Most of the exchanges today use SPAN ("Standard Portfolio Analysis of Risk") methodology, which was developed by the Chicago Mercantile Exchange in 1988, for calculating margins for options and futures.
