Financial statement analysis is the process of understanding the risk and profitability of a firm through analyzing reported financial information using accounting tools and techniques. It is the foundation for evaluating credit risk and doing fundamental company valuation. There are different types of financial statement analysis including long-term analysis for assessing solvency over time, short-term analysis for short-term creditors, internal analysis by insiders, and external analysis by outsiders with limited information. Other types are horizontal analysis comparing items over years, vertical analysis examining items as a percentage of a total, and dynamic analysis using data from multiple years.
