Liquidity ratios are most useful when they are used in comparative form. This analysis may be performed internally or externally. For example, internal analysis regarding liquidity ratios involves utilizing multiple accounting periods that are reported using the same accounting methods. Comparing previous time periods to current operations allows analysts to track changes in the business. In general, a higher liquidity ratio indicates that a company is more liquid and has better coverage of outstanding debts. Alternatively, external analysis involves comparing the liquidity ratios of one company to another company or entire industry. This information is useful to compare the company’s strategic positioning in relation to its competitors when establishing benchmark goals. Liquidity ratio analysis may not be as effective when looking across industries, as various businesses require different financing structures. Liquidity ratio analysis is less effective for comparing businesses of different sizes in different geographical locations.
