Final answer:
The quick ratio is a more stringent measure of liquidity compared to the current ratio as it considers only the most liquid assets, excluding inventory.
Step-by-step explanation:
The quick ratio provides a more rigorous indication of liquidity than does the current ratio. While both ratios are used to measure a company's ability to meet its short-term obligations, the quick ratio is considered more stringent because it excludes inventory and other current assets that are not as easily convertible to cash. Conversely, the current ratio includes all current assets, providing a broader view of the company's liquidity.
The quick ratio, often referred to as the 'acid-test ratio,' is calculated by taking the sum of a company's cash, marketable securities, and accounts receivable, and then dividing that by its current liabilities. This focus on the most liquid assets gives a clearer picture of a company's ability to pay off its debts quickly.
