Margin

Allows investors to buy securities by borrowing money from a broker. The margin is the difference between the market value of a stock and the loan a broker makes. Related: Security deposit (initial). In the context of hedging and futures contracts, the cash collateral deposited with a trader or exchanged as insurance against default.

Margin

1. Money that an investor has borrowed from a broker in order to buy securities. An investor who buys on margin can realize huge gains if the price of the security moves in a favorable direction; however, he/she also takes on a great deal of risk because it may not move in such a direction. See also: minimum maintenance, margin call.

2. A measure of how well a company controls its costs. It is calculated by dividing a company's profit by its revenues and expressing the result as a percentage. The higher the margin is, the better the company is thought to control costs. Investors use the margin to compare companies in the same industry as well as between industries to determine which are the most profitable. It is also called the profit margin.

Margin.

Margin is the minimum amount of collateral -- in either cash or securities -- you must have in your margin account to buy on margin, sell short, or invest in certain derivatives.

The initial margin requirement is set by federal law and varies from product to product. For example, to buy stock on margin, you must have at least 50% of the purchase price in your account.

After the initial transaction, maintenance rules set by the self-regulatory organizations, such as the New York Stock Exchange (NYSE) and NASD, apply.

Under those rules, you must have a minimum of 25% of the total market value of the margined investments in your account at all times. Individual firms may set their maintenance requirement higher -- at 30% or 35%, for example.

If your equity in the account falls below the maintenance level, you'll receive a margin call for additional collateral to bring the account value back above the minimum level.

To achieve laser analgaesia, the laser was positioned at a distance of 2mm from the tooth surface on the gingival margin and slowly moved for 2 min duration using 60 mJ energy and 20 Hz frequency power (low energy, high frequency).
Bleeding at the gingival margin or sulcus is often the first indicator of gingivitis.
