ACGL: undervalued.
Figures as of the 2026-10-19 close.
Arch Capital Group Ltd carries debt worth 0.18 times its shareholders' equity. Its current assets cover its short-term liabilities 0.50 times. For a bank or an insurer, debt is the raw material of the business, so this ratio does not mean what it means elsewhere.
We do not compute an Altman Z-Score for ACGL: the model was built for industrial companies, and the balance sheet of a bank or an insurer does not fit it.
It passes 5 of the 6 Piotroski F-Score tests we could evaluate, out of nine, which checks whether profitability, leverage and efficiency improved from one annual report to the next. Piotroski designed it for industrial companies: read it with care for a bank or an insurer. Which tests it passes, and the red flags in its accounts, are in the full analysis.
