How to work out what a stock is actually worth

People come to valuation expecting a calculation that outputs a number, which they then compare to the market price to see whether to buy. That is not what valuation does, and treating it that way produces false confidence, the most expensive commodity in investing.

What valuation actually does is force you to state, in numbers, what you believe about a business. The output is only as good as those beliefs, and its real value is that it makes them explicit enough to be challenged, including by you, later, when things change.

The only idea underneath all of it

A business is worth the cash it will generate for its owners over its remaining life, adjusted for the fact that money arriving in ten years is worth less to you than money arriving today.

Every valuation method is an approximation of that sentence. Some are elaborate, some are crude, and the crude ones are frequently more honest about their own uncertainty.

Method one: relative valuation

The most practical starting point. You compare the company against similar companies on a common measure, usually P/E, sometimes price-to-book for banks, sometimes EV/EBITDA for capital-heavy businesses.

The procedure: identify genuine peers, calculate the multiple for each, find the range, and then ask why your company sits where it does within that range. The answer is the analysis. If a company trades at a discount to its peers, either the market is wrong or it is right, and articulating which requires you to know the business.

Strength: fast, and grounded in actual traded prices. Weakness: if the whole sector is mispriced, relative valuation tells you nothing about that.

Method two: dividend-based valuation

Well suited to a market like PSX with many established dividend payers. You estimate the dividend stream and discount it back to today at a rate reflecting the risk you are taking.

The discipline is useful even when the arithmetic is rough, because it forces you to answer two questions directly: can this company keep paying this dividend, and what return do I require for the risk of finding out?

In Pakistan the required-return question is unavoidable, because the risk-free alternative is not theoretical. Government instruments have at times offered substantial yields. A stock has to be worth more than that alternative, after allowing for its risk, before it deserves your money.

Method three: earnings power

Rather than forecasting growth, estimate what the business earns in a normal year (not a boom, not a trough) and ask what you would pay for that stream.

This suits cyclical businesses, which are common on PSX: cement, steel, autos, fertiliser. Valuing a cyclical on peak earnings is one of the most reliable ways to lose money, because the multiple and the earnings collapse together.

Where beginners go wrong

1. Precision that the inputs do not support. A valuation accurate to two decimal places, built on a growth rate you guessed, is theatre.
2. Deciding the conclusion first. If you want to own the stock, you will find assumptions that justify it. Build the valuation before you form the view, not after.
3. Ignoring the balance sheet. A company with substantial debt is worth materially less to equity holders than the same operating business without it.
4. Assuming today continues. Currency, interest rates, and commodity prices all move, and Pakistani companies are highly exposed to all three.

What to do with the answer

Produce a range, not a number. If your work suggests the business is worth somewhere between X and Y, and the market price sits well below X, you have found something worth investigating further.

Then insist on a margin of safety: a gap between your estimate and the price you will pay, sized to your uncertainty. That gap is not timidity. It is the acknowledgement that some of your assumptions are wrong and you do not yet know which ones.
