Margin of safety study

April 4, 2019

Introduction


It is my personal finance research. I like to learn margin of safety today.

What is 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.

For example, if he were to determine that the intrinsic value of XYZ’s stock is $162, which is well below its share price of $192, he might apply a discount of 20% for a target purchase price of $130. In this example, he may feel XYZ has a fair value at $192 but he would not consider buying it above its intrinsic value of $162. In order to absolutely limit his downside risk, he sets his purchase price at $130. Using this model, he might not be able to purchase XYZ stock anytime in the foreseeable future. However, if the stock price does decline to $130 for reasons other than a collapse of XYZ’s earnings outlook, he could buy it with confidence.
