Stock Valuation Guide

Fundamental analysis

Expert Tips

• Gordon Growth Model Limits: Dividend Discount Model works best for mature, stable dividend payers. Don't use for high-growth tech stocks or non-dividend payers.
• Required Return Reflects Risk: Conservative stocks: 8-10%. Growth stocks: 12-15%. Higher required return = higher risk premium for uncertainty.
• Growth Rate Sustainability: Most companies can't sustain >7% dividend growth long-term. Be conservative—overestimating growth leads to overvaluation.
• Compare to Market Multiples: Cross-check intrinsic value with P/E ratio, PEG ratio, and competitor valuations for comprehensive analysis.

Essential Fundamentals — Valuation basics

Intrinsic Value Concept

• Present Value of Cash Flows: Stock worth sum of all future dividends discounted to present value. DDM formula captures this for dividend stocks.
• Margin of Safety: Buy when market price below intrinsic value. Provides cushion against estimation errors and market volatility.

Model Assumptions

• Constant Growth Assumption: Gordon Model assumes dividends grow at steady rate forever. Works for established companies, fails for cyclical businesses.
• Required Return Components: Required return = risk-free rate + equity risk premium. Should exceed company dividend yield plus growth expectations.

Advanced Strategies — Valuation refinement

Multi-Model Approach

• Cross-Validation: Use DDM alongside P/E ratios, DCF models, and comparable company analysis for robust valuation.
• Sensitivity Analysis: Test how intrinsic value changes with different growth rates and required returns to assess valuation range.
• Sector-Specific Adjustments: Utilities and REITs ideal for DDM. Tech companies need growth-adjusted models or DCF analysis instead.

Frequently Asked Questions

What is intrinsic value?

The true worth of a stock based on fundamentals (earnings, cash flow, assets). This calculator uses 3 methods (DCF, P/E, P/B) and averages them. If market price < intrinsic value, stock is undervalued.

What is DCF (Discounted Cash Flow)?

Values stock by projecting future free cash flows and discounting to present value. Most accurate for companies with predictable cash flows. Requires FCF per share and growth assumptions.

How does P/E valuation work?

Compares stock to industry peers. If industry average P/E is 20 and stock earns $8/share, fair value is $160. Stock trading at $120 would be undervalued vs sector.

What is a good PEG ratio?

PEG < 1 = potentially undervalued. PEG 1-2 = fairly valued. PEG > 2 = potentially overvalued. PEG accounts for growth: high P/E justified by high growth rate.

What is the Graham Number?

The Graham Number is Benjamin Graham's formula for conservative intrinsic value: √(22.5 × EPS × Book Value per Share). The "22.5" comes from his rules: never pay more than 15× P/E or 1.5× P/B. It only works when EPS and Book Value are both positive — it's most reliable for mature, asset-heavy companies, not high-growth tech stocks.

What is Margin of Safety?

Margin of Safety means buying a stock only when its price is significantly below your calculated intrinsic value — Graham recommended at least 33% discount. A stock worth $100 intrinsically should only be bought at $67 or below. This buffer protects you if your estimates are wrong or the market takes time to recognize the value.

Which valuation method is most accurate?

Depends on company type. DCF is best for mature companies with predictable cash flows. P/E is good for comparing within sectors. P/B is conservative for asset-heavy businesses. The Graham Number works best for stable, profitable companies with positive book value. This calculator combines all four methods for a balanced view.

Where do I find these inputs (EPS, FCF, Book Value)?

Find on Yahoo Finance, Google Finance, or company investor relations. Income statement: EPS. Cash flow statement: FCF. Balance sheet: Book Value. Most sites calculate per-share metrics automatically.

What growth rate should I use?

Use analyst estimates or historical 5-year average. Conservative: 5-7% (mature companies). Moderate: 10-15% (growth stocks). Aggressive: 20%+ (high-growth tech). Higher growth = higher risk.

When should I buy vs sell?

Strong Buy: >20% upside (deeply undervalued). Buy: 5-20% upside. Hold: ±5% of fair value. Sell: 5-20% downside. Strong Sell: >20% downside (deeply overvalued). Consider margin of safety (buy at 15-20% discount).

How accurate are the auto-filled values from the stock lookup?

The auto-filled figures (EPS, book value, FCF) are sourced from Financial Modeling Prep using the most recent completed annual report filing. They are accurate for that period. However, if the company has reported a more recent quarter since year-end, trailing twelve-month (TTM) figures may differ by 5–25% for fast-growing companies. For the most current numbers, cross-reference with Yahoo Finance or the company's latest 10-Q filing.

Is this calculator investment advice?

No. This calculator is for educational and research purposes only. Intrinsic value estimates are theoretical models — particularly DCF, which is highly sensitive to assumptions like growth rate and required return. A 1% change in the required return field can shift the DCF output by 15–25%. These outputs are useful for screening and framing a thesis, not as a definitive buy/sell signal. Always do your own due diligence and consult a licensed financial advisor before making investment decisions.
