"The Piotroski F-Score has been the only positive screener that has consistently done well over time despite 2018 market conditions. End of November results show it at 8.32% vs 2.9% for the S&P. Other “pure” value strategies continue to struggle in 2018. The dip in November hasn’t helped."

What is the Piotroski Score?

The Piotroski Score is named after its creator, Joseph Piotroski, a professor from Columbia university. It is a score used to evaluate the financial performance of a company and is based on 9 financial metrics that cover Profitability, Efficiency and Funding. 

​

Why is the Piotroski Score useful?

The usefulness of the Piotroski score is in its ability to filter companies when screening stocks. Stocks with a high Piotroski score have shown to produce relatively better returns than the market due to its quality rating factors.

Most of the measures contained incorporate looking at year on year change which indicates the direction of relevant key metrics, rather than just the absolute value.

2. Is operating cash flow positive?

3. Has return on assets increased year on year?

5. Is the long-term debt ratio lower than last year?

6. Has the current ratio increase from last year?

7. Has the company issued new shares?

8. Has the gross margin increase from last year?
