Graham and Dodd's foundational distinction, set out across the opening chapters of Security Analysis, is between intrinsic value — the value justified by the facts of the asset, its earnings power, and its dividend-paying capacity — and market price, which is set by the collective emotion of the moment. The book's central project is to give the analyst tools to estimate intrinsic value independently of market quotation, so that the gap between the two becomes the basis for buy and sell decisions. Graham and Dodd acknowledge that intrinsic value is not a single point but a range, and that the range is narrower for assets with predictable cash flows and wider for businesses exposed to cyclical or secular change. The contribution of the book is not to abolish the uncertainty but to discipline the analyst's process: estimate the range conservatively, require a price well below the lower bound, and refuse to pay any price simply because the market is paying it. The book treats the market's departure from intrinsic value as the recurring opportunity of value investing. Graham and Dodd document cases in which securities traded at discounts to net current assets, to working capital, or to the present value of contractual claims. The implicit message is that opportunities recur not because the market is irrational but because the market is structurally intermittent — prices overshoot in both directions and create windows for the patient analyst.

Graham and Dodd treat bond and preferred-stock analysis as the foundation of security analysis, not as a sidelight. The discipline of estimating whether a company can service its fixed charges under adverse conditions forces the analyst to confront the downside, the cycle, and the balance sheet, in a way that bull-market equity analysis too easily skips. Equity valuation inherits rigour from bond analysis, not the other way around. The book lays out specific quantitative tests for bond safety. The company should have earned its interest charges by a substantial margin across a span of years, including the worst years; the principal value of the debt should be amply covered by tangible assets; and the issue should be small relative to the company's total earning power. Graham and Dodd warn that advertised coupon is not safety, and that the high-grade label is routinely misapplied to issues that would not survive a real stress. For equities, the bond analyst's discipline becomes a demand that the equity buyer understand the company's fixed-charge structure, its working-capital position, and its earnings variability. Graham and Dodd argue that an equity buyer who ignores the bondholder's perspective is buying a residual claim without understanding what is senior to it. The same balance sheet that supports the bond supports the equity, and the analyst who skips the bond side misses half the company.

Graham and Dodd devote significant attention to securities trading below liquidating value, in bankruptcy, or in workout situations. They argue that the analyst who is willing to do the legal and accounting work on these obscure corners can earn returns competitive with much riskier common-stock investments, because the downside is structurally bounded by the asset coverage and the upside is contractual rather than speculative. The book catalogues cases in which senior securities of companies in reorganisation traded at a fraction of their asset coverage or contractual claim. The thesis is that reorganisation, by its mechanics, forces a partial distribution that the patient buyer can collect. Graham and Dodd distinguish between workouts whose timing is uncertain and arbitrage situations whose timing is known; the analyst's required return differs in each case. The broader principle is that the security analyst's edge lies in places where institutional capital will not follow. Distressed and workout situations are illiquid, legally complex, and unresearched by sell-side analysts. Graham and Dodd's working premise is that the inefficiency of these corners of the market is structural, and that an analyst willing to read the legal documents can earn a margin unavailable to the investor who only buys widely followed common stocks.
