Unlikely Manipulator

Above -1.78 = likely manipulator · -2.22 to -1.78 = grey zone

M-Score Trend

Beneish's 8-variable model estimates the probability of earnings manipulation. An M-Score above -1.78 signals elevated risk — companies in this range have historically been 3-5× more likely to be manipulating earnings. Scores between -2.22 and -1.78 fall in a grey zone warranting further investigation.
