Piotroski Score

The Piotroski score is a discrete score between 0-9 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 Piotroski score was named after Chicago Accounting Professor Joseph Piotroski, who devised the scale, according to specific aspects of company financial statements. Aspects are focused on the company’s accounting results in recent time periods (years). For every criterion met (noted below), one point is awarded; otherwise, no points are awarded. The points are then added up to determine the best value stocks.
