Margins have been too thin to measure a cycle against.
8% of the score, 9% here after data gaps
What the debt weighs against the profit that has to carry it.
6% of the score, 7% here after data gaps
Whether the reported profit arrives as cash, and whether the accounts show the usual signs of stretching.
Each criterion earns 0 to 100 points on the scale drawn under it, and the RyuScore is their average weighted 26, 18, 16, 14, 12, 8 and 6. Scales bend in the company's favour between their ends, so an ordinary figure is never already near zero. For PDFS, cycle position could not be measured from the filings, so it is taken out and the remaining weights scale up.
Built from the company's annual and quarterly filings with the SEC and today's share price. Banks, insurers and property trusts are not scored: their debt is their raw material, so these yardsticks mean something else there. Figures as of 2026-06-30, latest annual report FY2025.
