Why Fair Value Exists

Every valuation method ever invented is an attempt to answer one question: what is this business actually worth, regardless of what the market is quoting today? The answer is called intrinsic value, and the fact that it exists — separate from the price — is the foundation everything else in this course rests on.

Where value comes from

A business is worth the cash it can hand to its owners over its lifetime, adjusted for the fact that cash arriving in the future is worth less than cash today. That single sentence is the whole theory of valuation. Everything else is detail. Formally, intrinsic value is the present value of future owner cash flows:

$V = \sum_{t=1}^{n} \frac{CF_t}{(1 + r)^t} + \frac{TV}{(1 + r)^n}$

Do not worry about computing this by hand — the terminal does it for you. What matters is the shape of the idea:

• $CF_t$ is the cash the business produces in each future year $t$.
• $r$ is the discount rate — the annual return you require given the risk.
• $TV$ is the terminal value, capturing everything beyond the explicit forecast window.

Why a dollar tomorrow is worth less than a dollar today

The phrase "adjusted for the fact that future cash is worth less" is doing heavy lifting, so let us make it concrete. If you can earn 8% a year, then $100 today becomes $108 in a year. Run that backwards: $108 arriving a year from now is worth only $100 to you today, because $100 is all you would need to set aside now to replicate it. Dividing future cash by $(1+r)^t$ is just that logic applied year by year.

Why value and price drift apart

If value is so fundamental, why does the price ever differ from it? Because price is set moment to moment by buyers and sellers who are emotional, impatient, and reacting to the latest headline. Value, by contrast, is anchored to the slow-moving reality of the business — its cash generation, which does not lurch around every time sentiment shifts.

Over short horizons the two can diverge dramatically. A company can trade far above or far below what its cash flows justify for months or even years. But over long horizons, price tends to converge toward value, because eventually the cash a business produces (or fails to produce) becomes undeniable. That convergence is the mechanism by which disciplined, patient investors are eventually rewarded — and why chasing the ticker is not.

Why estimate it at all?

If you never estimate value, you have no way to know whether a price is cheap or expensive — you are left reacting to the ticker and to other people's opinions. Estimating value, even approximately, gives you an independent anchor. You can look at a $100 stock and say, "my analysis says it is worth $140," and act on that 40% gap rather than on the crowd's mood.

Crucially, the estimate does not need to be exact to be useful. A rough but honest valuation that says "worth roughly $130 to $150" is enough to tell you a $100 price is attractive and a $155 price is not. Precision is not the goal; a defensible anchor is. The rest of this course is about building that anchor well — and, just as important, knowing how much to trust it.

What comes next

You now have the core idea: value is discounted future cash, and price is what the crowd happens to be paying. The next lessons build the estimate piece by piece — the cash flows themselves, the growth that extends them, the discount rate that prices their risk, and the terminal value that captures the long tail. By the end you will be able to read any valuation, understand every input, and judge how much confidence it deserves.
