Putting It All Together: A Complete Valuation

Apply every method in a repeatable framework — triangulate multiple approaches and arrive at a conviction-backed fair value.

In this lesson you'll learn
A 7-step valuation framework you can apply to any stock
How to triangulate across multiple methods
How to decide: buy, watch, or pass
Common mistakes to avoid when valuing a stock

The complete 7-step valuation framework

Apply these steps in order for every stock you consider seriously. Steps 1–2 are qualitative; steps 3–7 are quantitative. Both matter — and a weak qualitative case should stop you before you waste time on the numbers.

1
Understand the business

Before touching any numbers: can you explain what this company does, how it makes money, and who its main competitors are in 2–3 sentences? If not, the numbers are meaningless.

2
Assess qualitative factors

Does the company have a durable competitive moat (pricing power, switching costs, network effects, cost advantage, intangible assets)? Is management's track record strong on capital allocation? Is the industry growing or shrinking?

3
Check key financial metrics

Revenue growth trend (3–5 yr). Gross and operating margins (expanding or shrinking?). Free cash flow generation. Debt levels (Net Debt/EBITDA < 3× is usually comfortable). Return on equity / invested capital.

4
Run multiple valuation methods

Calculate: (a) forward P/E vs. sector median and own 5yr history; (b) PEG ratio; (c) DCF using conservative growth estimates; (d) Graham Number (if applicable). Note the range of outputs.

5
Triangulate to a fair value range

Don't pick one method and ignore the others. The overlap zone across methods is your most reliable estimate. If three methods cluster around $70–85, use $75 as your central estimate.

6
Apply margin of safety

Subtract your margin (15–50% depending on business quality and certainty) from the central estimate to get your buy price. Only buy if the current stock price is at or below this level.

Decide: buy, watch, or pass

Buy: price ≤ your buy price AND qualitative case is strong. Watch: price is close but not quite there — add to your watchlist and monitor. Pass: business is poor quality OR price is far above fair value.

Triangulating across methods — a worked example

Imagine you're evaluating a well-known consumer company with stable earnings. Here's how the framework might play out:

Forward P/E comp
$88
Sector median: 22×; apply to $4 fwd EPS
DCF (conservative)
$82
8% FCF growth, 9% discount rate
Graham Number
$71
EPS $4 × BVPS $28 → √2,520
PEG check
1.3×
P/E 20 ÷ 15% growth — reasonable
Triangulated central estimate: ~$80
Buy at 25% MoS: <= $60
Watch: $60--75
Pass: above $80

The 5 most common valuation mistakes

Using a single method as the final answer

Always triangulate. One method can be wildly off; three converging methods give you real confidence.

Being too optimistic in your DCF assumptions

Use conservative growth rates. Test your model with pessimistic inputs. If it still looks cheap under bad assumptions, that's a strong signal.

Ignoring qualitative factors

A stock can look cheap on every metric and still be a value trap if the business is in structural decline. Always ask: why is it cheap?

Not requiring a margin of safety

Paying 'fair value' gives you no buffer for errors. Buying with a margin of safety is the single most important risk management tool in your arsenal.

Anchoring to the purchase price

If the business fundamentally deteriorates, your original valuation is wrong. Re-run the analysis with updated information. Be willing to sell at a loss if the investment case is broken.

The most important habit: write down your valuation thesis and the assumptions behind it before you buy. In 12–18 months, you can revisit and assess whether the business unfolded as expected — and learn from any gaps between prediction and reality. This is how investors improve over time.

3 questions · test what you've just learned
1

You've run three valuation methods on the same stock: DCF gives $95, P/E comp gives $85, and Graham Number gives $72. The stock trades at $80. What is the most reasonable conclusion?

2

In the valuation framework, what does 'qualitative due diligence' refer to?

3

You've identified what looks like an undervalued stock. When does the framework suggest you act?

✓ Key takeaways from Lesson 7
The 7-step framework: understand the business → qualitative check → financial metrics → multiple valuations → triangulate → apply MoS → decide.
Triangulation across DCF, P/E, Graham Number and PEG gives you a reliable fair value range — not a false-precision single number.
Buy only when price is below your margin-of-safety-adjusted buy price AND the qualitative case is strong.
The most important habit: write down your thesis before you buy, and review it regularly against what the business actually delivered.
