A common-size statement is a financial statement that expresses all of the items on the statement in terms of a common base, such as 100%. This makes it easier to compare the financial statements of different companies or of the same company over time.
A comparative statement is a financial statement that shows the financial information for two or more periods side-by-side. This makes it easier to see how the company’s financial performance has changed over time.
Trend analysis is a technique that is used to identify trends in financial data. This can be done by plotting the data on a graph or by calculating the percentage change from one period to the next.
