HORIZONTAL ANALYSIS
Back to GlossaryDefinition
Compares historical data, such as ratios, or line items, over a number of accounting periods.
Summary
Horizontal analysis is a financial analysis technique that examines changes in financial statement items over multiple time periods, typically expressed as percentages or dollar amounts. It helps identify trends, growth patterns, and areas of concern by comparing the same line items (like revenue, expenses, or assets) across different years or quarters. This 'horizontal' view allows analysts to see how a company's performance has evolved over time, making it easier to spot patterns and make informed business decisions.
Usage Context
Understanding horizontal analysis is crucial when learning financial statement analysis, trend identification, performance evaluation, and making investment or management decisions based on historical financial data.
Common Confusions
- Confusing horizontal analysis with vertical analysis (which compares items within the same period)
- Thinking horizontal analysis only uses percentages when dollar amounts are also valid
- Assuming that horizontal analysis always requires the same base year for all comparisons
- Believing that horizontal analysis can only be applied to financial statements
