Value Investing: Intrinsic Value, Evidence, and Margin of Safety
Value investing compares the price available today with a conservative range of what an asset may be worth. The process requires more than a low multiple: it connects business economics, cash flow, balance-sheet claims, management decisions, and uncertainty.

01
Price versus value
Treat valuation as a range of outcomes
Market price is observable; value is estimated. A sound estimate begins with the economic engine and the cash that can ultimately reach the owner. It then accounts for reinvestment, competition, financing, dilution, taxes, and the time value of money.
Because each input is uncertain, a range is more honest than a single target. The width of the range is information. A wide range can justify a lower position size, a larger required discount, or a decision to pass.
02
Evidence stack
Build the thesis from durable evidence
Normalized economics
Through-cycle volume, margins, credit losses, maintenance spending, and working capital.
Balance-sheet claims
Debt, leases, pensions, preferred securities, dilution, and other claims ahead of common equity.
Competitive durability
Customer behavior, substitution, pricing power, regulation, and the cost of maintaining relevance.
Capital allocation
Reinvestment, acquisitions, debt reduction, distributions, and issuance measured per share.
Governance
Incentives, disclosure, related parties, and whether decision-makers treat owners as partners.
03
Model with humility
Use scenarios and reverse valuation
Scenario valuation
Construct downside, base, and upside cases that are internally consistent. Stress operating drivers and financing together rather than changing one spreadsheet cell at a time. The downside should explain a mechanism, not merely apply a lower multiple.
Probability weights can help compare opportunities, but the unweighted scenarios remain valuable. They show what capital may be at risk if the thesis is wrong.
Reverse valuation
Start with the market price and solve for the growth, margins, returns, or recovery values it appears to require. Compare those implied expectations with history, industry structure, and execution capacity.
This approach reduces the temptation to build a model that simply confirms a preferred conclusion.

Portfolio translation
Pair margin of safety with position sizing
Estimate quality
- How predictable are the cash flows?
- How much value depends on a distant terminal assumption?
- What information is independent and verifiable?
Loss mechanisms
- Can leverage, dilution, obsolescence, or governance cause permanent impairment?
- Is liquidity adequate for the holding period?
- What evidence breaks the thesis?
Portfolio context
- Which existing holdings share the same drivers?
- What is the maximum acceptable loss in dollars?
- Does the expected return justify the opportunity cost?
