Which of the following is NOT a common measure of liquidity?

The asset turnover ratio is not considered a common measure of liquidity. Liquidity measures are primarily focused on a company's ability to quickly convert assets into cash to meet short-term obligations. The current ratio, quick ratio, and cash ratio are all specifically designed to assess a company's liquidity position.

The current ratio evaluates the relationship between current assets and current liabilities, offering insight into whether a company can cover its short-term debts with its short-term assets. The quick ratio, often seen as a more stringent measure, excludes inventory from current assets, focusing on the most liquid assets. The cash ratio takes this a step further, measuring cash and cash equivalents against current liabilities to see if those immediate resources can settle debts.

In contrast, the asset turnover ratio assesses how efficiently a company utilizes its assets to generate revenue. While it provides valuable insights into operational efficiency, it does not directly measure liquidity. Therefore, identifying the asset turnover ratio as not being a common measure of liquidity is accurate, as it serves an entirely different purpose in financial analysis.
