We can also compare financial information of one company with other companies in the industry which is known as cross-sectional analysis. The good thing about common-size analysis is that it is really easily to do and also interpreting the results is not so difficult. Even the users who are not proficient in analysis techniques can gain insight of company’s financial performance to some extent from common size financial statements i.e. income statement and statement of financial position.
