Three commonly used tools for financial statement analysis are as under• Horizontal Analysis: evaluates a series of financial statement data over a period of time. It is used primarily in intra-company comparisons. Two features in published financial statements facilitate this type of comparison. First, each of the basic financial statements presents comparative financial data for a minimum of two years. Second, a summary of selected financial data is presented for a series of 05 to 10 years or more. Example • Vertical Analysis: evaluates financial statement data by expressing each item in a financial statement as a percentage of a base amount. It is used in both intra- and intercompany comparisons. Example • Ratio Analysis: expresses the relationship among selected items of financial statement data. This technique is used in all three types of comparisons- intra-company, inter-company, and industry-wide average.
