Fundamental analysis is a method used to determine an asset's intrinsic value by examining its underlying economic and financial factors. Investors employ this approach to make informed decisions about stocks, bonds, and other securities.

Key aspects of fundamental analysis include:

1. Economic Factors: The overall economic environment significantly influences a company's performance. Factors like GDP, inflation, and unemployment rates provide valuable insights into the economy's health.

2. Financial Statements: These statements, including the balance sheet, income statement, and cash flow statement, offer crucial information about a company's financial health, assets, liabilities, revenues, and expenses.

3. Earnings: A company's profitability, represented by its net income (earnings), is a critical factor. Strong earnings can positively impact stock price and dividend payouts.

4. Valuation Ratios: These ratios, such as the price-to-earnings (P/E) ratio, price-to-book (P/B) ratio, and price-to-sales (P/S) ratio, help compare a company's stock price to its earnings and other financial metrics. These ratios provide valuable insights into a stock's valuation.

5. Industry Analysis: Evaluating the industry's overall health and prospects is crucial. Factors like supply and demand, competition, and the regulatory environment all play a significant role.

By carefully considering these factors, investors can utilize fundamental analysis to make informed decisions about buying, selling, or holding securities. This approach is particularly valuable for long-term investors as it helps identify companies with strong financial foundations and growth potential.
