Margin of safety: the distance between price and value

A high-quality business can still be a poor investment when the starting price leaves no room for error.

Intrinsic value is a range, not a precise point. A discount to a conservative range helps absorb mistakes in growth, margins and the cost of capital.

The required margin changes with rates, liquidity and the market's appetite for duration. This principle applies across regimes.

Abundant liquidity can compress risk premiums and push quality assets beyond reasonable expectations. Tighter liquidity can reverse that process.

Buy only when the price offers a reasonable discount to a conservative value range.

Business quality and reinvestment exceed the assumptions used in the valuation range.

The apparent discount reflects a structural deterioration that the model has not captured.

No numerical probability is published for this framework note. The purpose is to compare scenarios, not imply precision.

Improving cash conversion, disciplined capital allocation and expectations resetting to a more realistic level.

Overestimating durability, underestimating cyclicality or treating a low multiple as evidence of value.

The thesis fails when the economics, balance sheet or competitive advantage no longer support the original value range.

Demand a margin of safety that reflects both business uncertainty and the current cost of capital.

Active framework. Reassess assumptions when material facts change, not merely when price moves.
