A very woolly term - a banner headline - a throwaway phrase - for a whole family of financial measures.
These could include: -
Net Profit % to Sales
...and many more.
It doesn't mean anything at all really - but is just a collective term for every measure of financial return. It could include interest on a loan, dividend on a share, return on an investment and more. So use with confidence...it's nice and generic and never likely to catch you out.
