Operating margin

How Tickdelta computes it

Operating income ÷ revenue

TTM means the last twelve months: the last fiscal year, plus this year's year-to-date and minus last year's, both from the latest 10-Q when it is newer than the 10-K.

For a company that holds crypto at fair value (Strategy, miners) the price moves of the coins are inside operating income, so the margin can be far below zero in a year the coin fell.
