What Is a Company Worth?

Fundamental analysis is the process of determining a company's intrinsic value — what the business is actually worth, regardless of what the stock market says it's worth today. When intrinsic value is significantly above the current stock price, investors buy. When it's below, they sell or avoid.

This is the approach used by Warren Buffett, Benjamin Graham, and virtually every successful long-term investor in history. It treats stocks as pieces of real businesses, not ticker symbols that go up and down.

The Three Pillars of Fundamental Analysis

1. Quantitative Analysis (The Numbers)

This is the hard data from financial statements:

Revenue growth — Is the top line growing, and at what rate? Consistent 10%+ revenue growth is excellent.
Profit margins — Gross margin (revenue minus cost of goods), operating margin (after operating expenses), and net margin (the bottom line). Higher and expanding margins indicate a competitive advantage.
Return on Equity (ROE) — Net income ÷ shareholder equity. Measures how efficiently management uses investor capital. 15%+ is generally strong.
Debt levels — Debt-to-equity ratio, interest coverage. High debt amplifies returns in good times and destroys companies in bad times.
Free cash flow — Cash from operations minus capital expenditures. This is the real money the business generates. Earnings can be manipulated; free cash flow is harder to fake.

2. Qualitative Analysis (The Business)

Numbers alone don't tell the full story:

Competitive advantage (moat) — Does the company have something that protects it from competitors? Brand power (Coca-Cola), network effects (Meta), switching costs (Microsoft), economies of scale (Amazon), patents (pharma companies).
Management quality — Are the executives shareholder-friendly? Do they allocate capital wisely? Do they have significant personal ownership? A great business with bad management is a bad investment.
Industry dynamics — Is the industry growing, stable, or declining? A great company in a dying industry faces strong headwinds.
Addressable market — How big is the opportunity? A company with a $50 billion market and a $1 trillion addressable market has enormous runway.

3. Valuation (The Price)

A wonderful company can be a terrible investment if you pay too much. Common valuation methods:

P/E ratio — Price relative to earnings. Compare to historical averages and peers.
PEG ratio — P/E divided by earnings growth rate. Accounts for growth.
Discounted Cash Flow (DCF) — Projects future cash flows and discounts them to present value. The theoretically correct method, but highly sensitive to assumptions.
Price-to-Book (P/B) — Useful for financial companies and asset-heavy businesses.

Key Takeaways

Fundamental analysis answers one question: "Is this company worth more than its current stock price?"
Study the numbers (quantitative), the business (qualitative), and the price (valuation). All three matter.
Buying great companies at fair prices beats buying fair companies at great prices.
