This document provides an overview of security analysis approaches. It discusses fundamental analysis, which involves macroeconomic, industry, and company analysis to evaluate performance and value. Macroeconomic analysis considers economic variables' impact on companies. Industry analysis examines the life cycle, characteristics, and profit potential. Company analysis assesses financials, marketing, accounting policies, profitability, and capital structure. Technical analysis uses historical price and volume data to identify trends that may predict future performance. Fundamental analysis attempts to determine intrinsic value, while technical analysis does not evaluate value directly.
