# Beneish M-Score Screen 41 Qualifying in UK

This is a short-selling strategy based on Professor Beneish's M-Score - this is a mathematical model that uses eight financial ratios from the company's financial statements to assess the degree to which the earnings may have been manipulated. It is similar to the Altman Z-Score, but it is focused on detecting earnings manipulation rather than bankruptcy. The research suggests that a score less negative than -1.78 indicates a strong likelihood of a firm being a manipulator. Here is the link to the original Detection of Earnings Manipulation paper as well as the subsequent paper - The Relation between Accruals and Earnings Manipulation. The screen below highlights companies that have had a M-score above the threshold for two years in a row in order to reduce the likelihood that a given year's result is coincidental or a rogue data input error.

Detection of Earnings Manipulation

by Messod Beneish

In his "Detection of Earnings Manipulation" paper, Beneish found that the M-Score test could correctly identify 76% of manipulators, whilst only incorrectly identifying 17.5% of non-manipulators. In a subsequent 2007 paper -  The Predictable Cost of Earnings Manipulation - Beneish examines the use of the M score as a stock selection technique (over the period 1993-2003). The M-score strategy apparently generated a hedged return of nearly 14% per annum.
