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.
