def FineSelectionFunction(self, fine):
filtered_fine = [x for x in fine if x.FinancialStatements.IncomeStatement.EBIT.OneMonth
and x.FinancialStatements.BalanceSheet.InvestedCapital.OneMonth
and x.FinancialStatements.BalanceSheet.PreferedStockEquity.OneMonth]
ROIC = [map(lambda x: (FinancialStatements.IncomeStatement.EBIT.OneMonth)/((FinancialStatements.BalanceSheet.InvestedCapital.OneMonth)+(FinancialStatements.BalanceSheet.PreferedStockEquity.OneMonth)), filtered_fine)
sortedByROIC = sorted(ROIC, reverse=True)

The FinancialStatements is the property of elements in filtered_fine. For example
def FineSelectionFunction(self, fine): filtered_fine = [x for x in fine if x.FinancialStatements.IncomeStatement.EBIT.OneMonth and x.FinancialStatements.BalanceSheet.InvestedCapital.OneMonth and x.FinancialStatements.BalanceSheet.PreferedStockEquity.OneMonth] sortedByROIC = sorted(filtered_fine, lambda x: (x.FinancialStatements.IncomeStatement.EBIT.OneMonth)/((x.FinancialStatements.BalanceSheet.InvestedCapital.OneMonth)+(x.FinancialStatements.BalanceSheet.PreferedStockEquity.OneMonth)), reverse=True) return [i.Symbol for i in sortedByROIC]You should also make sure the value is non-zero before calculating the ROIC with the factor value. Financial statements data often released quarterly. Therefore, one month value might be zero. You should use "ThreeMonths" to obtain the quarterly value.
