Is this stock fairly priced?
Eight valuation methods (P/E, PEG, Graham, P/B, P/S, DDM, FCF Yield, EV/EBITDA) running in parallel. Fill in what you know; the toolbox unlocks methods as you go.
How the math works
Each method takes data you already have and outputs an implied fair value or comparative ratio. Inputs unlock methods progressively as you fill them in.
- P/E: price ÷ EPS — quick comparative metric. Best for profitable, established companies.
- PEG: P/E ÷ growth rate — fair value when ≈ 1.0. Adjusts P/E for growth.
- Graham Intrinsic Value:
V = EPS × (8.5 + 2g)— the value-investing classic. Modified version adjusts for AAA bond yield. - P/B: price ÷ book value per share — for asset-heavy businesses (banks, REITs).
- P/S: price ÷ revenue per share — for unprofitable growth companies (early-stage tech).
- DDM (Gordon Growth):
V = D / (k − g)— for stable dividend payers (utilities, consumer staples). - FCF Yield: free cash flow ÷ market cap — harder to manipulate than earnings.
- EV/EBITDA: for cross-border comparisons and capital-intensive industries.
Why we run all eight in parallel: no single method works for every stock. P/E ignores debt; P/S ignores profitability; DCF is only as good as your growth assumption. Running multiple methods side-by-side flags disagreement — which is usually where the interesting investment decisions live.

How to read the results
- Stock valuation for beginners (2-3 numbers, 30 seconds) — start with P/E. Layer in other methods as you get comfortable.
- P/E vs PEG: when one misleads and the other rescues — P/E 15 at 3% growth is more expensive than P/E 40 at 35% growth. Why growth-adjusted matters.

P/E vs PEG: Why a 'Cheap' P/E 15 Stock Is Often More Expensive Than P/E 40
P/E ranks two stocks. PEG ranks them growth-adjusted, and often flips the verdict. We worked through five real-world-shaped examples where P/E and PEG disagree and explain which one wins.
