Specifically, it quantifies how optimally the business deploys its assets and handles its liabilities to maximize revenues and minimize unnecessary expenses.However, at times, it becomes difficult to measure the efficiency level of a company. This is why one must consider the popular efficiency ratios listed below while selecting stocks.Healthcare Services Group, Electromed, UMB Financial,Shell and MACOM Technology Solutions have made it through the screen process:Efficiency Ratios – to Be ConsideredReceivables Turnover: This is the ratio of 12-month sales to four-quarter average receivables. It shows a company's potential to extend its credit and collect debt in terms of that credit. A high receivables turnover ratio, or the "accounts receivable turnover ratio" or "debtor's turnover ratio," is desirable as it shows that the company is capable of collecting its accounts receivables or that it has quality customers.Asset Utilization: This ratio indicates a company's capability to convert assets into output and is thus a widely known measure of efficiency level. It is calculated by dividing total sales over the past 12 months by the last four-quarter average of total assets. Like the above ratios, high asset utilization may indicate that a company is efficient.Inventory Turnover: The ratio of the 12-month cost of goods sold (COGS) to a four-quarter average inventory is considered one of the most popular efficiency ratios. It indicates a company's ability to maintain a suitable inventory position. While a high value indicates that the company has a relatively low level of inventory compared to COGS, a low value indicates that the company is facing declining sales, which has resulted in excess inventory.Operating Margin: This efficiency measure is the ratio of operating income over the past 12 months to sales over the same period. It measures a company's ability to control operating expenses. Hence, a high value of the ratio may indicate that the company manages its operating expenses more efficiently than its peers.Here are the top five stocks that made it through the screen:Healthcare Services GroupIndivior Pharmaceuticals Group provides housekeeping, laundry, linen, facility maintenance and food services to the healthcare industry, including nursing homes, retirement complexes, rehabilitation centers and hospitals.
