Second screen: Eliminate all companies with an F score below 5.[2]
[2] The F-Score (the Piotroski F-score) is a measure of the financial strength of a company.
The F-score is the sum of the scores for each of nine tests.
Each test scores one for a pass and zero for a fail.
The tests are:
i) net profit is positive;
ii) operating cash flow is positive;
iii) net profit ÷ total assets at beginning of year, minus the same number for the previous year is positive;
iv) operating cash flow is greater than net profit;
v) long term debt ÷ by average assets has not increased;
vi) the Current ratio has increased (the change is more than zero, so even a negligible increase passes the test);
vii) no raising of ordinary (common) equity over the previous year: this test is passed if the company did not issue any ordinary shares; viii) gross margin has improved over the previous year; and
ix) asset turnover has increased.

..The Global 100 is the most extensive data-driven corporate sustainability assessment in existence, and inclusion is limited to a select group of the top 100 large-cap companies in the world. Launched in 2005, the annual Global 100 is announced each year during the World Economic Forum in Davos. The Global 100 methodology for evaluating companies' sustainability or "clean capitalism" performance was cited as a leading global practice (by SustainAbility in their Rate the Raters research program, Phase 4).
