Description
The NetProfitMargin function returns the ratio of a company's net income (income less the bottom line) to that same company's total sales or revenues, expressed in percent. By default, the value is returned for the currently selected symbol and based on the annual reporting data. To specify a different symbol for this function, modify the value of the symbol input parameter. To use quarterly data instead of annual, assign the FiscalPeriod.QUARTER constant to the fiscalPeriod input parameter.
