Margin of Safety

Margin of safety is a principle of investing in which an investor only purchases securities when their market price is significantly below their intrinsic value. In other words, when the market price of a security is significantly below your estimation of its intrinsic value, the difference is the margin of safety. Because investors may set a margin of safety in accordance with their own risk preferences, buying securities when this difference is present allows an investment to be made with minimal downside risk.
