The highest GAAP operating margin

GAAP operating margin

Ranked from the filings of the companies this site has read, under . 50 of them report a figure for this; the rest are absent rather than ranked last, because a filing that does not carry a number is not a company that scores badly on it.

How this measure is worked out

Operating income ÷ revenue × 100

Operating income (also called EBIT) is what is left of sales after the cost of the product and the cost of running the company, before interest and tax. Revenue is total sales to customers before any cost is taken off. Both over the trailing twelve months.

50% earns a 10; set margin_scale per ticker for sectors that cannot reach it

What this ranking is not

It is not advice, and a high place is not a recommendation. A company can lead on one measure and fail on every other; that is the reason this site scores five dimensions rather than one and lets you weigh them yourself.

It also ranks only what has been read. A company whose filings are not in this database cannot appear here however well it would have done, and a company whose filing does not tag this figure is absent rather than last.
