Margin of safety
Margin of safetyThe term given by Benjamin Graham, 'the father of value investing', to the idea that if you buy shares for less than two thirds of their net asset value, you automatically have a cushion against any deterioration in the company's trading position in the future. Put another way, 'buy cheap'.Graham's view was that it is extremely difficult to accurately predict a company's future earnings. For an investment to be 'safe', therefore, he liked to see a margin between the value of its net current assets and its share price. If the share price was below the net current assets divided by the number of shares in issue, he would consider buying it.One of the problems with Graham's approach is that in bull markets it is very difficult to find companies that fulfil his criteria. A second problem is that many of the fastest growing companies in modern economies are those whose assets are intangible - for instance, the value of their intellectual property. Under the Graham rubric, these sorts of assets would be excluded.

Initial margin requirementInitial margin requirement
When buying securities on margin, the proportion of the total market value of the securities that the investor must pay for in cash. The Security Exchange Act of 1934 gives the Board of Governors of the Federal Reserve the responsibility to set initial margin requirements, but individual brokerage firms are free to set higher requirements. In futures contracts, initial margin requirements are set by the exchange.
Margin account (stocks)Margin account (stocks)
A leverageable account in which stocks can be purchased for a combination of cash and a loan. The loan in the margin account is collateralized by the stock; if the value of the stock drops sufficiently, the owner will be asked to either put in more cash, or sell a portion of the stock. Margin rules are federally regulated, but margin requirements and interest may vary among broker/dealers.
Initial marginInitial margin
The payment which investors have to pay to a broker to trade on margin, commonly used in trading futures and contracts for difference. Initial margin is usually set at a percentage of the value of the contracts being traded. For example, a trader who buys long CFDs with a contract value of £12,000 might be required to deposit £2,400 (20%) with the broker as initial margin.The attraction of margin trading for traders is that they are effectively using the broker's money to speculate, and if successful can get a higher return on investment than by only using their own money. Put another way, their £2,400 of cash buys them exposure to £12,000 of shares, whereas if they were trading the shares themselves it would give them exposure only to £2,400 of shares.The flip side is that margin trading magnifies losses as well as profits, so if the trader is unsuccessful it can be very risky.
