Principle 02
Margin of Safety
Capital is deployed only when there is a large gap between price and value. Price is not separate from risk; it is part of the underwriting.
The first investment lesson was delivered in 600 B.C. by Aesop: a bird in the hand is worth two in the bush.
Investing is about evaluating whether we are trading the bird in the hand today for birds in the bush: how many birds we may get in the future, how long it may take, and what price makes that exchange sensible.
Fifty cents for a dollar
The simplest version of the discipline is buying something for meaningfully less than it is worth. Ideally, we would like to pay fifty cents for a company that is worth a dollar.
That phrase is easy to say and hard to practice. Intrinsic value is not printed on a screen. It has to be estimated, and estimates can be wrong.
Why the gap matters
The margin of safety exists because the future is uncertain. A good business can still be a poor investment at the wrong price. A thoughtful thesis can still fail if it depends on perfect execution, distant outcomes, or a market narrative replacing cash economics.
We look for situations where nothing heroic needs to happen. We would rather give up some excitement than depend on assumptions that leave no room for ordinary disappointment.
That does not eliminate risk. It is how we try to avoid making risk larger than it needs to be.
