margin-of-safety

To apply a margin of safety, estimate the intrinsic value range of an investment, compare it with the current market price, and enforce a minimum safety threshold that scales upward as valuation uncertainty increases.

Evaluating downside protection requires estimating the investment's intrinsic value range after a price drop and comparing it to the current price to ensure the discount provides a sufficient buffer against potential estimation errors.

The required margin of safety grows with uncertainty, demanding a larger discount between intrinsic value and current price when business, industry, or valuation inputs are less certain to adequately protect against meaningful loss.

You should not rely on a margin of safety when intrinsic value cannot be reasonably estimated or when the investment lacks a clear downside buffer, as the threshold mechanism depends on quantifiable valuation ranges.
