Growth
What is Operating Income YoY?
Growth in operating profit against the same period a year earlier.
How it is calculated
This period’s operating income divided by the same period last year, minus one.
How to read it
Operating income growing faster than revenue means margins are expanding, the strongest form of growth.
Where the numbers come from
Scrutar computes Operating Income YoY from the figures each company reports to the SEC in its annual and quarterly filings, using the XBRL data attached to those filings.
