Valuing a stock means estimating what a business is actually worth, then comparing that to its market price. This guide walks through a complete valuation sample using the three most common methods — so you can see exactly how professional analysts think about price vs. value.
The Three Core Valuation Methods
| Method | What It Does | Best For |
|---|---|---|
| DCF (Discounted Cash Flow) | Projects future cash flows and discounts them to present value | Companies with predictable cash flows |
| Comparable Multiples | Compares valuation ratios (P/E, EV/EBITDA) against peers | Quick relative valuation |
| Book Value / Asset-Based | Looks at what the company owns minus what it owes | Asset-heavy businesses, banks, REITs |
No single method gives the "right" answer. Professional analysts use all three and triangulate.
Sample Company Profile
Let's value a fictional company, TechCo Inc., using real-world-style numbers:
- Revenue (TTM): $5.0 billion
- Net income: $750 million
- Free cash flow: $900 million
- Total debt: $2.0 billion
- Cash: $1.5 billion
- Shares outstanding: 200 million
- Current stock price: $80
- Market cap: $16.0 billion
- Book value of equity: $6.0 billion
- Expected FCF growth (next 5 years): 12% per year
- Terminal growth rate: 3%
- Discount rate (WACC): 10%
Method 1: DCF Valuation
The DCF model estimates the present value of all future cash flows the business will generate.
Step 1 — Project Free Cash Flows
| Year | FCF Growth | Projected FCF |
|---|---|---|
| Year 1 | 12% | $1,008M |
| Year 2 | 12% | $1,129M |
| Year 3 | 12% | $1,264M |
| Year 4 | 12% | $1,416M |
| Year 5 | 12% | $1,586M |
Step 2 — Calculate Terminal Value
Terminal value captures all cash flows beyond Year 5, assuming growth slows to a sustainable rate:
Terminal Value = Year 5 FCF x (1 + terminal growth) / (discount rate - terminal growth)
TV = $1,586M x 1.03 / (0.10 - 0.03) = $23,335M
Step 3 — Discount Everything to Present Value
| Year | Cash Flow | Discount Factor (10%) | Present Value |
|---|---|---|---|
| Year 1 | $1,008M | 0.909 | $916M |
| Year 2 | $1,129M | 0.826 | $933M |
| Year 3 | $1,264M | 0.751 | $949M |
| Year 4 | $1,416M | 0.683 | $967M |
| Year 5 | $1,586M | 0.621 | $985M |
| Terminal | $23,335M | 0.621 | $14,491M |
| Total Enterprise Value | $19,241M |
Step 4 — Calculate Equity Value Per Share
Equity Value = Enterprise Value - Debt + Cash
Equity Value = $19,241M - $2,000M + $1,500M = $18,741M
Intrinsic value per share = $18,741M / 200M shares = $93.71
Current price is $80. The DCF suggests TechCo is undervalued by about 17% based on these assumptions.
Key Sensitivity
DCF is highly sensitive to assumptions. Changing the discount rate from 10% to 11% or the growth rate from 12% to 10% significantly shifts the result. Always run multiple scenarios.
Method 2: Comparable Multiples
This method values TechCo by comparing it to similar companies.
P/E Ratio (Price-to-Earnings)
TechCo's P/E = $16,000M market cap / $750M net income = 21.3x
| Company | P/E Ratio |
|---|---|
| Peer A | 25.0x |
| Peer B | 22.5x |
| Peer C | 18.0x |
| Peer average | 21.8x |
TechCo's P/E (21.3x) is close to the peer average (21.8x) — suggesting it's roughly fairly valued on an earnings basis.
If TechCo deserved the peer average multiple: $750M x 21.8 = $16,350M market cap = $81.75/share (slightly above $80).
EV/EBITDA
Enterprise Value = Market cap + Debt - Cash = $16,000M + $2,000M - $1,500M = $16,500M
Assuming EBITDA of $1,200M: EV/EBITDA = 13.75x
Compare this to peers to see if TechCo trades at a premium or discount on an operating basis.
When Multiples Mislead
Multiples assume peers are correctly valued. If the entire sector is overvalued, a stock that looks "cheap" relative to peers might still be expensive in absolute terms. Multiples are a shortcut, not a substitute for understanding the business.
Method 3: Book Value
Book value = Total assets minus total liabilities (shareholders' equity on the balance sheet).
TechCo's book value: $6.0 billion = $30/share
Price-to-Book ratio = $80 / $30 = 2.67x
This means investors are paying 2.67 times the accounting value of the company's net assets. For a technology company with significant intangible value (brand, software, customer relationships), a P/B above 1.0 is normal. For a bank or industrial company, a P/B much above 1.5x might signal overvaluation.
When Book Value Matters
- Banks and financial institutions — assets are mostly financial instruments carried near market value
- REITs — real estate assets are tangible and revalued regularly
- Distressed companies — book value sets a floor on liquidation value
- Capital-light tech companies — book value is often less meaningful because the real value is in intangibles not on the balance sheet
Putting It All Together
| Method | Implied Value Per Share |
|---|---|
| DCF (base case) | $93.71 |
| P/E comps | $81.75 |
| Book value | $30.00 (floor) |
| Current price | $80.00 |
The DCF suggests meaningful upside. Comps suggest fair value. Book value confirms you're not paying a wildly excessive premium for net assets.
A reasonable conclusion: TechCo appears modestly undervalued to fairly valued, with potential upside if growth assumptions play out. The margin of safety is moderate — this isn't a screaming bargain, but it's not overpriced either.
The Limitations
Every valuation method has blind spots:
- DCF depends entirely on assumptions — garbage in, garbage out
- Multiples tell you relative value, not absolute value
- Book value misses intangible assets and future earnings power
- None of them account for management quality, competitive dynamics, or industry disruption
This is why valuation is the starting point of investment research, not the end. You also need to understand the business model, read the SEC filings, assess competitive position, and evaluate management's capital allocation track record.
