Piotroski Score

What is Piotroski Score?

The Piotroski score is a discrete score between zero and nine that reflects nine criteria used to determine the strength of a firm's financial position. The Piotroski score is used to determine the best value stocks, with nine being the best and zero being the worst. The nine aspects are based on accounting results over a number of years; a point is awarded each time a standard is met, resulting in an overall score.

If a company has a score of eight or nine, it is considered a good value. If a company has a score of between zero and two points, it is likely not a good value.

  1. Profitability

  2. Leverage, liquidity, and source of funds
