A company that has a moat can usually maintain or even expand their Gross Margin. A company can increase its Gross Margin in two ways. It can increase the prices of the goods it sells and keeps its Cost of Goods Sold unchanged. Or it can keep the sales price unchanged and squeeze its suppliers to reduce the Cost of Goods Sold. Warren Buffett believes businesses with the power to raise prices have moats.

Cost of Goods Sold is also directly linked to another concept called Inventory Turnover:

Arch Coal Inc's Inventory Turnover for the three months ended in Dec. 2014 is calculated as:

 Inventory Turnover = Cost of Goods Sold / Average Inventory = 610.646 / 199.956 = 3.05

* All numbers are in millions except for per share data and ratio. All numbers are in their own currency.

Inventory Turnover measures how fast the company turns over its inventory within a year. A higher inventory turnover means the company has light inventory. Therefore the company spends less money on storage, write downs, and obsolete inventory. If the inventory is too light, it may affect sales because the company may not have enough to meet demand.

Usually retailers pile up their inventories at holiday seasons to meet the stronger demand. Therefore, the inventory of a particular quarter of a year should not be used to calculate inventory turnover. An average inventory is a better indication.
