Gross Margin (Marx) equals Gross Profits (sales minus cost of goods sold) / Total Assets (depreciation deducted)
Professor Robert Novy-Marx in a paper The Quality Dimension of Value Investing defined a quality company as one that had a high gross income ratio.
In the paper Robert showed that this ratio has the same market beating capability as other valuation ratios such as the price to earnings ratio for example.
How to use the ratio
Available as a screening ratio: Yes
Available as an output column ratio: Yes (Look for it under the Quality heading)
How to select the highest Gross Margin Marx companies
To find companies with the highest Gross margin Marx values (highest Gross Margin companies) set the slider from 0% to 10%.
All ratios are calculated on a trailing 12 months (TTM) basis.
This means the last twelve months (not the company’s financial year) is compared to the same period in the past.
We do this to make sure that the screener data includes the latest, most up to date, financial results of the company.
