n/aHow the RyuScore works
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 DUOL, cycle position and balance sheet could not be measured from the filings, so they are 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.
