Price vs Value

A price is an observation, a value is an estimate

The price of a share is a fact: the most recent transaction two people agreed to, recorded and reported. It is also the least informative kind of fact, because it tells you what one marginal buyer and one marginal seller thought for one instant, out of millions of holders who did nothing. Value is not a fact at all. It is the present value of the cash the business can hand to its owners over its life, discounted at a rate that reflects how uncertain that cash is. Nobody knows it. Every estimate of value is somebody’s model of the future, which is why two competent analysts can look at the same company and write $60 and $95 on the same day and both be reasoning honestly. That asymmetry has a consequence worth taking seriously: if the price is a fact and the value is an opinion, then disagreeing with the price means disagreeing with the crowd, and the crowd is usually right about most things. Most of the time the price is a good estimate, because thousands of people are paid to look for the parts of it that are wrong. The opportunity, when there is one, comes from a specific disagreement you can name rather than from a general feeling that a stock is expensive. One year of a business, two very different numbers — Last price: $62.00 · Earnings per share: $1.75 · Price as a multiple of earnings: 35.4× · Your estimate of value, at a 9% discount rate: $199 implied by the growth, or $44 on peer multiples · Which one is right?: Neither is "right" — they disagree about growth ← A low price is not a discount. A $5 stock at 10× earnings is cheap only against something — its own history, its peers, or the growth you expect. The multiple is a claim about the future dressed up as a number about the present.

Why a gap exists at all

Graham’s parable is the clearest answer ever written. Imagine a business partner, Mr. Market, who every day offers to buy your stake or sell you his, at a price he sets from his mood rather than from the facts. Some days he is euphoric and names absurd numbers; some days he is terrified and names insulting ones. He is not there to tell you what the business is worth. He is there to offer you a transaction. The parable matters because it separates two questions that feel like one: what is this worth, and what is it trading for? Most investors answer the second and believe they have answered the first. Mr. Market is also the reason a gap can persist for years — he is not obliged to agree with you, has no deadline, and in the short run can be right about something that has not happened yet. So a gap closes in one of two ways. Either the business delivers the cash flows your estimate assumed, and the price comes to you; or you were wrong, and the price was the honest estimate all along. Both happen constantly, which is why the useful discipline is to write down what has to be true before you buy, and to compare the business against that list rather than against the price. The estimate itself has structure. Because value is discounted cash, it comes apart into the cash the business generates and the rate you demand for waiting — and only the first of those is a fact about the company.

How to disagree with the price responsibly

If the price is a fact and value is an opinion, then buying a stock is disagreeing with a large, well-funded crowd, and most disagreements are wrong. The difference between a thesis and a feeling is whether the disagreement can be stated specifically enough to be checked. “It is too expensive” cannot be checked. “The market is assuming 14% growth for a decade and this industry has never grown faster than 6%” can be, and it fails loudly and early when the next two years print 5%. That is the discipline Graham’s Mr. Market is really teaching. You do not argue with him about whether a stock is cheap; you write down what has to be true for your estimate to hold, and then you watch the business rather than the quote. The list is short: the growth rate you assumed, the margin you assumed, the capital it takes to fund that growth, and the discount rate you demanded. Four numbers, each with a source, each able to be wrong on its own. The payoff is not certainty, it is calibration. When a position goes against you, a written list tells you whether the business broke or the price moved — and those two demand opposite responses. Without the list, every decline looks like a bargain or a verdict depending on how you feel that morning. This is the shape of the whole subject: F12 builds the model, F21 runs it backwards to see what the price already assumes, and F22 writes it up. The habit starts here, with the first stock you look at.

A range, and the discount that makes it useful

An estimate of value that arrives as a single number is a false precision. Different assumptions about growth, margins and the rate you discount at will produce a spread of defensible values for the same business — often wide enough that the price sits inside the range rather than clearly above or below it. The useful output of a valuation is therefore a **range plus a view about where the price sits in it**, because “this is worth $47.30” invites you to check only whether the price is above or below a number you invented, while “this is worth somewhere between $38 and $55, and I have more confidence in the bottom of that range than the top” tells you how much you are relying on the optimistic assumptions. The range also explains why the discipline has a margin of safety rather than a target price. If your estimate can be wrong by twenty percent and the future is uncertain in ways your model does not contain, then buying at a small discount to your central estimate is buying a business and a guess at once. The margin of safety is the difference between the price and the *lower* end of the plausible range, which is why the same business can be a good purchase for one investor and a bad one for another with the same valuation: the price is one input and the required discount is the other. And there is a third number worth carrying, which is what has to happen for the gap to close. A gap between a price and a value is a claim about the future: either the market is wrong, or your estimate is. Naming the mechanism — buybacks at a discount to value, a catalyst that changes the multiple, a business whose cash flows simply accumulate until the price follows — turns a belief into a thesis with a clock on it. The version that has no mechanism is the one that becomes a five-year wait and a lesson in opportunity cost. One business, one set of numbers, three defensible answers ($1,000m next-year cash flow) — Discount 10%, growth 3%, margins hold: $1,400m — the central estimate · Discount 12%, growth 2%, margins compress: $1,000m — the low end · Discount 8%, growth 5%, margins expand: $3,300m — the high end, and the one to distrust The most dangerous version of this idea is a range so wide that every price is inside it. If your low case is half your high case, the honest conclusion is that you cannot value the business with confidence, not that you have permission to buy at any price in between.

Cheap, or broken?

The expensive mistake in this subject is not paying too much for a good business. It is buying a business that is cheap because it is getting worse, and holding it while “the value gets recognised” for a decade. Every screen that finds low multiples finds both kinds at once, and the ratio cannot tell them apart — so the ratio cannot be the analysis. The distinction to draw is between a **price** that has fallen and a **value** that has fallen. A multiple can compress because a sector has been re-rated, because a fund was forced to sell, because the company was deleted from an index, or because a large holder had a tax reason to realise a loss. None of those change the business. Alternatively the earnings power can be permanently impaired — by a competitor, a regulation, a technology, a lost customer — and then the low multiple is the market being right about a smaller business. The two look identical on a screen, and the whole job is deciding which one you have. Five checks separate them, and they are deliberately ordered by how quickly each one can be answered. First, is the decline cyclical or structural? Ask what specifically would have to happen for the previous level of earnings to return, and then ask whether that thing is the kind of thing that happens. Second, can the balance sheet wait? A cheap stock with a refinancing due in a year is not cheap; it is a claim on a negotiation, and cheapness is only available to a business that can afford to be patient. Third, is the profit turning into cash? Accrual earnings that fail to convert over several years are the signature of numbers that were recognised rather than earned. Fourth, how is management behaving — buying back stock at a high multiple, or acquiring to cover a shrinking core, tells you the inside view differs from the screen’s. Fifth, who is selling? Index deletion and fund closures create cheapness with no information in it, while an executive selling into weakness carries the opposite. The reframe that keeps the order straight is this: “cheap” is a comparison between a price and a value, and the value has to be established first. Work in the other order, from the multiple toward an argument, and the ratio quietly does the analysis for you. Establish what the business can earn and what it is worth, and the multiple becomes an observation rather than a thesis. The honest caveat is that some businesses are both cheap and permanently worse, and no amount of analysis fixes that. What distinguishes the ones that work is that the impairment is specific, bounded and reversible, and that you can name it. If the thesis cannot be stated as “this particular thing is temporary and here is why”, it is not a value thesis. It is a hope attached to a low number. • A falling price and a falling value look the same on a screen and are opposites in a portfolio. • Forced selling, index deletion and re-ratings create cheapness without information. • Cheapness requires a balance sheet that can wait for the thesis to play out. • Establish value first and read the multiple second, or the ratio becomes the argument. The quickest version of the test is one sentence long: name the specific thing that is temporarily wrong, and name what would have to happen for it to stop being wrong. A thesis that cannot be written that way is a multiple with a story attached.
