There are tens if not hundreds of different ways to look at a company's profits, so it's best to keep in mind the options. For companies that sell a lot of inventory, such as a medical device company or a company in the retail industry, one good measure is gross profit margin -- the percentage of profits taken after deducting "cost of goods sold."

COGS is the cost attributed to inventory sold and represents the largest expense for many companies centered on selling physical products. Although gross margins vary widely across industries, one universally positive sign is when companies see consistent increases in their gross margin.

This generally indicates more aggressive pricing (and higher demand for products) or simply a change in accounting methods. However consistent increases support the idea that the source is more aggressive pricing and higher demand.
