Glossary

Fundamental analysis has its own language and vocabulary. Terms like "intrinsic value," "economic moat," "quality of earnings," "free cash flow," "return on invested capital," and "working capital" recur throughout this book, and their precise definitions matter significantly. A misunderstanding of what "earnings" means in a given context (GAAP earnings versus operating earnings versus free cash flow) can lead to a valuation error that costs you money and derails your thesis. This glossary provides reference definitions for the key concepts and terms introduced across all chapters of this book.

Use this chapter as a working resource when you encounter unfamiliar terminology during your own fundamental analysis and research. Each entry provides a clear, practical definition—not a theoretical academic definition focused on precision at the expense of clarity. The goal is not to memorize definitions, but to build your working vocabulary so you can read financial research, SEC disclosures, company earnings calls, analyst reports, and investment commentary with confidence and precision, knowing exactly what terms mean when you encounter them. Many of these terms appear in multiple contexts throughout this book and in financial literature, and their meanings can overlap or shift depending on context. This chapter helps clarify where definitions diverge and how context affects usage.

The glossary is organized alphabetically for quick lookup during active research sessions when you hit a term that is unfamiliar or that you want to verify. Where a term has a related concept, cross-references point you to related entries or to the chapters where those concepts are developed more fully with examples. This resource is meant to be used actively during research, not read cover to cover—bookmark this chapter and refer back to it whenever a term or concept stops you short or when you want to verify a definition.

Financial metrics and ratio definitions​

This glossary defines key financial metrics and ratios used throughout the book: profitability ratios like ROE, ROA, and ROIC (what percent return does the company earn on capital?), valuation multiples like P/E and EV/EBITDA (how expensive is the stock relative to earnings or enterprise value?), efficiency metrics like asset turnover and days sales outstanding (how quickly does the company convert assets into revenue and cash?), and solvency measures like debt-to-equity and interest coverage (how much debt can the company service?). Each definition explains what the metric measures, how to calculate it from financial statements, and what it tells you about the business's quality and attractiveness.

Investment and valuation concepts​

Beyond pure financial metrics, this glossary also defines conceptual terms crucial to fundamental analysis: intrinsic value (what the business is truly worth based on economics), margin of safety (the discount between price and value), economic moat (sustainable competitive advantage), working capital (cash tied up in current assets and liabilities), free cash flow (the cash a business can distribute), terminal value (value beyond the explicit forecast period), discount rate (the cost of capital and required return), and quality of earnings (how real are reported profits in cash terms?). These concepts tie together the numerical analysis and the qualitative judgment that characterize good fundamental analysis. Understanding them deeply is essential to applying the frameworks throughout the book.
