The SEC`s Office of Investor Education and Advocacy publishes this Investor Bulletin to inform investors of the use of marginal accounts for the purchase of securities, including associated risks. A «margin account» is a kind of broker account in which the broker lends the investor cash to buy securities using the account. The margin increases the purchasing power of investors, but also exposes investors to the potential for significant losses. Here`s what you need to know about Margin. Margin purchases relate to the purchase of cash securities borrowed by a broker, with the securities purchased being used as collateral. The result is an increase in earnings or loss of securities. The securities are used as collateral for the loan. Net worth – the difference between the value of the securities and the loan – is initially the amount of use.

The margin equity rate is a term used by speculators, which represents the amount of their trading capital held at a given time as a margin. Traders would rarely (and unintentionally) hold 100% of their capital as a margin. There is a good chance of losing all their capital at some point. On the other hand, if the margina equity rate is so low that the trader`s capital corresponds to the value of the futures contract itself, they would not benefit from the inherent leverage that is implied in futures trading. A conservative trader could hold a margin rate of 15%, while a more aggressive trader could hold 40%.

If this results in the market value of the security of a margina account being covered by the revised margin, the broker or exchange immediately issues a «margin call» requiring the investor to reconcile the margin account.

If the investor does not reconcile the account, the broker can sell the investor`s security in order to reconcile the account.
