Reported earnings show no manipulation flags Beneish M-score, a forensic model that detects earnings-manipulation patterns (receivables outrunning sales, margins slipping, accrual-heavy profit).
Weak, deteriorating fundamentals Piotroski F-score, nine pass/fail tests of year-over-year financial health across profitability, balance sheet and efficiency. 7 to 9 is strong, 0 to 3 weak.
