Today's operating margin of 16% is 2.43x its normal 6.8%: near a peak, where margins tend to fall back. Normal is half the 10 year median, half the last four years, so a margin that has held is not taken for a peak.

How 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. Where a criterion cannot be measured from the filings it is taken out and the remaining weights scale up; a company needs 60% of the weight covered, and always a price, to get a score.
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.
