Horizontal Analysis: translation
A procedure in fundamental analysis in which an analyst compares ratios or line items in a company's financial statements over a certain period of time. The analyst will use his or her discretion when choosing a particular timeline; however, the decision is often based on the investing time horizon under consideration.
For example, when you hear someone saying that revenues increased by 10% this past quarter, that person is using horizontal analysis. Horizontal analysis can be used on any item in a company's financials (from revenues to earnings per share), and is useful when comparing the performance of various companies.
