The Piotroski Score is a discrete score ranging from 0 to 9, used to evaluate the financial strength of a firm. Named after its creator, University of Chicago accounting professor Joseph Piotroski, this score is derived from nine distinct criteria focusing on various aspects of a company’s financial statements. It is particularly popular among value investors aiming to identify potentially undervalued stocks with solid financial health.
Origins and Concept
Joseph Piotroski introduced the Piotroski Score in his 2000 paper, “Value Investing: The Use of Historical Financial Statement Information to Separate Winners from Losers.” The score was designed to identify potential winners among value stocks, filtering out those with high financial distress.
Components of the Piotroski Score
The Piotroski Score is calculated based on nine specific criteria, divided into three main categories: profitability, leverage/liquidity, and operating efficiency.
Profitability
- Net Income: Positive net income earns one point.
- Operating Cash Flow (OCF): Positive OCF earns one point.
- Return on Assets (ROA): An ROA showing positive change earns one point.
- Quality of Earnings: OCF exceeding net income earns one point.
Leverage/Liquidity
- Decrease in Leverage: A decrease in the ratio of long-term debt to assets earns one point.
- Increase in Liquidity: An increase in the current ratio compared to the previous year earns one point.
- Absence of Equity Dilution: No new shares issued in the last year earns one point.
Operating Efficiency
- Gross Margin: An increase in the gross margin ratio earns one point.
- Asset Turnover: A positive change in the asset turnover ratio earns one point.
Interpretation and Application
A company can score between 0 and 9, with each point representing one favorable criterion met:
- High Score (8-9): Indicates a strong financial position and high potential for value appreciation.
- Medium Score (5-7): Suggests moderate financial health.
- Low Score (0-4): Signals a weak financial position, potentially high distress.
Example Calculation
Consider a company, ABC Corp, to understand the practical application of the Piotroski Score:
- Profitability: ABC Corp has a net income of $500,000, positive OCF, an improving ROA, and an OCF greater than its net income. It scores 4/4 in this category.
- Leverage/Liquidity: The company reduced its debt, improved its current ratio, and did not issue new shares. It scores 3/3 here.
- Operating Efficiency: It also reports a higher gross margin and better asset turnover. Thus, it scores 2/2 in this category.
ABC Corp would achieve a perfect Piotroski Score of 9, indicating robust financial health.
