What is a stock's fair value, and how do you work it out?

AlphaTeak Research Team··3 min read
A stock's fair value is what the underlying business is worth based on the cash it can earn over time, not its current share price. You estimate it from normalised earnings, free cash flow, and conservative growth, then compare it to the price to judge whether a stock is cheap or dear.
A share price compared against an estimated fair value range

Fair value is the anchor of every sound investment decision. The price is what you see on the screen. Fair value is what the business is actually worth. When the two drift apart, opportunity (or danger) shows up.

Here is how to think about a stock's fair value, step by step:

  1. Start with what the business earns. Look at profit, and better still free cash flow, the cash left after the company runs and reinvests in itself.
  2. Ask what is normal. Strip out one-off gains and losses so you value the through-the-cycle earning power, not a single boom or bust year.
  3. Estimate growth conservatively. Modest, defensible growth beats an optimistic guess that has to go right for the number to hold.
  4. Bring the future back to today. Cash earned years from now is worth less than cash today, so distant profits count for less.
  5. Compare to the price. Well below your estimate, the stock is potentially undervalued. Well above, it is potentially dear.

What "fair value" actually means

Fair value, also called intrinsic value, is an estimate of what a company is worth based on the cash it can generate for its owners over its life. It is not the share price, and it is not what someone might pay for it tomorrow. It is a judgment about the business itself.

Because it is an estimate, fair value is a range, not one perfect number. Two careful investors can reach different figures and both be reasonable. The goal is not false precision. It is to know roughly what a business is worth, so you are not at the mercy of the daily price.

Why price and value are not the same

In the short run, a share price reflects mood: fear, greed, headlines, and momentum. In the long run, it tends to track what the business earns. That gap between mood and worth is where patient investors make their money.

A booming company can be a poor investment if you overpay, and an ordinary company can be a fine one if you buy it cheaply. Price is what you pay. Value is what you get.

Common ways to estimate fair value

There is no single formula, and the right tool depends on the business.

MethodBest forThe idea
Discounted cash flowSteady, predictable earnersAdd up future free cash flows, discounted back to today
Earnings multipleComparable, mature companiesApply a sensible multiple to normalised earnings
Asset basedBanks, property, holding companiesValue what the company owns, net of what it owes
Dividend basedReliable income payersValue the stream of dividends it can sustainably pay

Whatever the method, the discipline is the same: use normalised numbers, be conservative, and treat the answer as a range.

The margin of safety

Because your estimate can be wrong, you do not buy at fair value. You buy well below it. That gap, the margin of safety, is your protection against a mistake, bad luck, or a future that turns out worse than expected. The larger the discount to fair value, the more room you have to be wrong and still do well.

Common mistakes

  • Valuing a peak year as if it were normal. Record profits often revert, so the cheap-looking multiple at the top is a trap, not a bargain.
  • Chasing a story instead of the cash. If a company cannot turn its growth into real cash for owners, the story is not worth much.
  • Confusing a great business with a great investment. Even the best company is a poor buy at the wrong price.
  • Pretending to be precise. A tight single number gives false confidence. A sensible range, bought with a margin of safety, serves you far better.

The bottom line

Fair value is what a business is worth, judged by the cash it can earn over time. Estimate it conservatively, compare it to the price, and only buy when the price sits comfortably below your estimate. Do that consistently and you let the market's moods work for you instead of against you.
