How to Value Stocks
(And Why Most Investors Get It Wrong)
Most investors ask the same question:
“Is this stock cheap or expensive?”
It sounds simple.
But answering it properly is one of the hardest parts of investing.
Because a stock price on its own tells you almost nothing.
What matters is how that price compares to what you’re actually getting in return.
A Stock Is a Claim on Future Cash Flows
At its core, a stock represents ownership in a company.
And that ownership gives you access to future profits.
So when you buy a stock, you’re doing one thing:
→ Paying today for cash flows you expect to receive in the future.
That’s the foundation of valuation.
Why Price Alone Means Nothing
A stock trading at €10 isn’t necessarily cheap.
A stock trading at €500 isn’t necessarily expensive.
Because price only makes sense in context.
You always need to consider:
- Earnings
- Growth
- Risk
- The macro environment
Without that, price is just a number.
The Most Common Shortcut: Multiples
Since valuing a company precisely is difficult, investors use shortcuts.
The most common one is the Price-to-Earnings (P/E) ratio.
It tells you how much you’re paying for each unit of earnings.
Example:
- P/E of 10 → paying €10 for €1 of earnings
- P/E of 30 → paying €30 for €1 of earnings
Lower might seem better.
But that’s not always true.
Growth Changes Everything
A company growing quickly deserves a higher valuation.
Because future earnings are expected to be larger.
That’s why companies like Nvidia often trade at higher multiples.
Investors aren’t just buying what the company earns today.
They’re buying what it could earn in the future.
Interest Rates Matter More Than You Think
Valuation doesn’t happen in isolation.
It depends heavily on the macro environment — especially interest rates.
When rates are low:
- Future earnings are more valuable
- Investors are willing to pay higher prices
When rates rise:
- Future cash flows are discounted more heavily
- Valuations tend to fall
This is why many growth stocks declined during tightening cycles.
Not because the business failed —
but because the environment changed.
Risk Is Always Part of the Price
Two companies with the same earnings can trade at very different valuations.
Why?
Because of risk.
- Stable, predictable businesses → higher valuation
- Uncertain or volatile businesses → lower valuation
Investors demand compensation for uncertainty.
And that shows up in the price.
There Is No “Correct” Value
One of the biggest misconceptions:
That a stock has a single fair price.
It doesn’t.
Valuation always depends on assumptions:
- How fast will it grow?
- How stable are earnings?
- What will interest rates do?
Change those assumptions — and the valuation changes.
What Most Investors Get Wrong
Many investors focus too much on the present.
They look at:
- Current earnings
- Recent news
- Short-term performance
But markets are forward-looking.
They price expectations — not current reality.
That’s why a stock can look expensive today and still go higher.
A Better Way to Think About It
Instead of asking:
“Is this stock cheap?”
Ask:
- What am I paying for?
- What growth is expected?
- What needs to happen for this price to make sense?
That shift changes everything.
Final Thought
Valuation isn’t about finding a perfect number.
It’s about understanding the relationship between:
→ price, growth, risk, and the environment.
Because a stock is never just cheap or expensive.
It’s only cheap or expensive relative to expectations.
