The Beneish M-Score is a statistical screen created to identify companies whose accounting patterns look more like historical manipulators than clean reporters. It is useful because it forces you to ask better questions. It is dangerous if you treat it as a verdict.
What it is good for
- screening large lists of companies
- surfacing accounting patterns worth a manual review
- adding discipline to your earnings-quality process
What it is not good for
- proving fraud
- replacing the filing
- making a buy or sell decision by itself
How to use it correctly
If the Beneish signal flashes:
- inspect receivables and revenue recognition
- inspect margins and expense capitalization
- compare cash flow with profit
- read management's explanation in MD&A
The model works best as an escalation tool. When it says "look closer," listen.
