Investing Glossary

Investing terms can often feel confusing, especially for beginners. This glossary is designed to give you clear, simple definitions of the most important concepts in fundamental investing so you can understand how markets work and make better financial decisions.

Fundamental investing focuses on analyzing businesses based on their financial performance, competitive advantage, and long-term value. To do that effectively, you need to understand the language investors use—from basic terms like assets and cash flow to more advanced concepts like return on invested capital (ROIC) and discounted cash flow (DCF).

In this investing glossary, each term is explained in plain language with a focus on real-world understanding—not technical jargon. Whenever possible, definitions are connected to broader investing concepts so you can see how each idea fits into the bigger picture.

You’ll learn key terms related to:

Financial statements and accounting concepts
Business analysis and valuation methods
Stock market fundamentals and investment strategies
Risk, return, and long-term decision-making

If you’re just getting started, this glossary is the perfect place to build your foundation. If you’re already learning, it will help reinforce and clarify the concepts that matter most.
