Financial analysis involves assessing business entities, projects, budgets, and forecasts from a financial perspective by analyzing financial statements. It helps with decision making related to investing and financing. External analysis is conducted by outsiders to determine liquidity and ability to generate funds, while internal analysis is done by management to ensure business functions align with goals. The objectives of financial analysis are to determine profitability, financial position, operational efficiency, and future risks and opportunities. Common types of analysis include vertical analysis, horizontal analysis, growth rates analysis, profitability analysis, and liquidity analysis. Financial analysis provides useful insights but has limitations as it relies on historical data and does not consider intangible assets.
