DuPont analysis
(重定向自Du Pont Identity)

DuPont Analysis (also known as the dupont identity, DuPont equation, DuPont Model or the DuPont method) is an expression which breaks ROE (return on equity) into three parts.
The name comes from the DuPont Corporation that started using this formula in the 1920s. DuPont explosives salesman Donaldson Brown invented this formula in an internal efficiency report in 1912.
