Price vs Value
Howard Marks has a phrase he returns to again and again: "The relationship between price and value is the most important thing in investing."
Not value alone. Not price alone. The relationship between the two.
A great business at a terrible price is a bad investment. A mediocre business at an extraordinary bargain can be a good one. This seems obvious stated plainly, yet most investors spend the vast majority of their time analyzing businesses and almost none analyzing whether the current price makes sense relative to the value they've estimated.
The valuation chart
On every stock page on The Ledger Terminal, you'll find a chart that plots two lines: the actual stock price over time and an estimated fair value based on the company's fundamentals.
The fair value line is derived from the company's actual earnings, book value, and historical valuation ranges — all pulled from SEC filings going back fifteen years. It's not a price target. It's not a prediction. It's an estimate of what the business would be worth if the market valued it at typical multiples for its own history.
When the price line runs well above the fair value line, the market is pricing in optimism beyond what the fundamentals support. When the price runs below fair value, the market is pricing in pessimism — or simply neglecting the stock.
Why the gap matters
The gap between price and fair value is where returns come from. Or, put differently, it's where risk hides.
"The biggest investing errors come not from factors that are informational or analytical, but from those that are psychological." — Howard Marks
When a stock has been rising for years, it feels safe. The business is well-known, the narrative is compelling, the momentum is strong. But if the price has risen faster than the fundamentals, the gap has widened — and the margin of safety has shrunk. What feels safest is often most risky.
Conversely, when a stock has been beaten down, it feels dangerous. The headlines are bad, the narrative is negative, everyone you talk to has an opinion about why it's broken. But if the fundamentals haven't deteriorated nearly as much as the price suggests, the gap has widened in your favor. What feels most dangerous can be most rewarding.
This is the central paradox of investing that separates professionals from amateurs. Amateurs chase comfort. Professionals chase value.
Mean reversion is the engine
Over long periods, price and value tend to converge. Not smoothly, not predictably, and not on any schedule you can trade around — but they do converge. This is mean reversion, and it's the closest thing to a law of nature that exists in financial markets.
A company trading at twice its historical fair value can stay expensive for years. But eventually, either the price comes down or the fundamentals grow into the valuation. Conversely, a company trading at half its fair value won't stay cheap forever — either the market recognizes the disconnect or the business deteriorates to justify the price.
Your job as an investor isn't to predict when convergence happens. It's to position yourself on the right side of the gap so that convergence works in your favor rather than against you.
How to use the chart
When evaluating any stock, the valuation chart gives you context that a price chart alone cannot:
Is the stock expensive relative to its own history? If the price line is well above the fair value line, you're paying a premium. That premium needs to be justified by accelerating growth, expanding margins, or some structural change in the business. If you can't articulate why, you're paying too much.
Is the stock cheap relative to its own history? If the price line is below fair value, dig into why. Is the business genuinely deteriorating? Or has the market overreacted to a temporary setback? The chart shows you the gap; the financial table shows you whether the fundamentals support a recovery.
What's the trend in fair value itself? A rising fair value line means the business is growing and compounding. A flat or declining fair value line means the business is stagnating or shrinking. The best investments are businesses with rising fair value lines where the price has temporarily fallen below.
The discipline
The hardest part isn't understanding the concept. It's maintaining the discipline to act on it. Buying when prices are below value requires buying when the news is bad and your gut says don't. Selling (or at least not buying more) when prices are above value requires restraint when everyone around you is making money.
This isn't a system you can automate. It's a framework for thinking — one that keeps you focused on the only question that truly matters: Am I getting more value than what I'm paying?
Every stock on The Ledger Terminal shows this relationship between price and fair value, updated with the latest SEC filing data. Use it not as a trading signal, but as a compass. Over time, that compass makes all the difference.
