10 Stocks With A Perfect Piotroski Score by Matt Hogan, founder of finbox.io

Joseph Piotroski, a Stanford accounting professor, developed a set of rules to find companies with strong Liquid Balance Sheets, Profitability, and Operating Efficiency. Professor Piotroski proposed screening for stocks based on a checklist that awards one point for each matched criterion. To learn more about the criteria, view Stock Screen: Piotroski F-Score.

In his famous paper, Professor Piotroski explained that an “investment strategy that buys expected winners and shorts expected losers generates a 23% annual return between 1976 and 1996.” I used the finbox.io stock screener to find stocks included in the Russell 1000 index that scored perfectly on Piotroski’s test. There were only 10 companies (or 1%) that passed all nine checks.
