The document discusses various financial statement analysis techniques including comparative statements, common size statements, and trend analysis.
Comparative statements allow comparison between firms, within a firm, and over time. Common size statements express each financial statement item as a percentage of a total to allow comparison. Trend analysis uses a base year to show percentage changes in items over multiple years.
The techniques help analyze profitability, liquidity, and solvency, but consistency is needed and they may provide misleading results if accounting principles change or inflation is not considered. Dynamic analysis uses percentages and absolute data over time while static analysis examines item relationships within a single statement. Reasons for trends in sales and expenses are also outlined.
