Which analysis method focuses on analyzing dollar amounts for a single company over multiple years?

The method that focuses on analyzing dollar amounts for a single company over multiple years is horizontal analysis. This approach involves comparing financial data over different periods to identify trends, patterns, and changes in various financial metrics. By examining the dollar amounts from one year to the next, horizontal analysis allows stakeholders to assess a company's performance over time, providing insights into revenue growth, expense management, and profitability trends.

This analysis helps in understanding whether a company's financial situation is improving or deteriorating, guiding management decisions, investment evaluations, and strategic planning. It essentially serves as a tool for longitudinal analysis, emphasizing the importance of temporal changes in financial performance, which is crucial for stakeholders looking to gauge the future viability of the company.
