Fundamental analysis measures a security's intrinsic value by examining related economic and financial factors to determine a company's true value. There are three types of fundamental analysis: economic analysis, which evaluates the costs and benefits of economic conditions and factors in a country; industrial analysis, which examines the industry a company operates in; and company analysis, which looks at the company's financial statements and management. Economic analysis considers macroeconomic metrics like GDP, inflation, interest rates, and tax structure to evaluate investment opportunities.
