Shorting Stocks with the Beneish Model

Executive Summary
The Beneish Model is a tool developed by Professor Messod Beneish back in 1999 that identifies public companies who have (abnormally) manipulated their earnings. For my project, I decided to develop a tool that would calculate the Beneish “M-score” on all of the stocks in the S&P 500, and then summarize the stocks with Beneish scores below the given threshold that show manipulated earnings. With this knowledge, I then plan to short those stocks.


This is of interest to me because I’ve traded stock options before, and have been trying to get back into it this year. Shorting stocks is where I have the most experience and have had the most success, so this tool fits right into my trading philosophy.
