Arch Capital Group (ACGL)
Financieras / Seguros
Bermuda-based insurer/reinsurer with three diversified segments (insurance, reinsurance, mortgage), an 82.7% combined ratio and high-teens operating ROE, trading at 9× TTM earnings and ~1.45x book value despite underwriting quality — a discount that reflects the market's fear of reinsurance cycle normalization, not an impaired business.

The essentials
- Three underwriting segments (Insurance, Reinsurance, Mortgage) with an 82.7% consolidated combined ratio (TTM), and the mortgage segment exceeding $1,000M of underwriting income for the fourth consecutive year.
- 17.1% operating ROE in FY2025 (18.9% in FY2024), well above the 10% bar, with book value per share growing 22.6% in FY2025 and accelerated buybacks reaching ~$3.5bn TTM after issuing $2bn in senior notes in Jun-2026.
- Trades at 9× TTM earnings and ~1.45x book value — cheap for the ROE it generates — because the market is discounting rate pressure in property catastrophe reinsurance (January 2026 renewals down -10%/-20%).
Intrinsic value — two valuation methods
By both methods, the value today (DCF $355 · Multiples $168) exceeds the market price ($101).
Pillars of the analysis
The verdict — today vs 5 years
Today — with margin of safety: at $101 trades ~40.1% below its value discounted to today (~$168) — the wide discount we require (≥38%, equivalent to a ~15% annual return); the risk is covered by the margin, not the rate.
At 5 years — Muy infravalorado: the target price ($209) plus dividends yield above the required average return (10%) — the business compounds.
The bridge: the return at 5 years comfortably exceeds the risk-free rate (4.5%) — and the discount reaches the required margin of safety.
Thesis
The business
Arch combines three specialty underwriting lines (insurance, reinsurance, mortgage) with an uncommon capital-cycle discipline: an 82.7% combined ratio (TTM) and 17.1% operating ROE (FY2025), well above the 10% bar. Underwriting quality is real and verifiable in the filing, not an accounting artifact.
The valuation
Valued on P/E over net income to common, with an exit multiple of 9× within the 11-15x band for specialty insurers (§4). With the base-case earnings and buyback trajectory, the 5-year value implies a +16% annual return, Very undervalued versus the current price.
The margin of safety
There is a margin of safety: the market's perception is meaningfully worse than reality. At market price the stock trades at 9× TTM earnings and ~1.45x book value with a high-teens ROE — multiples typical of a declining insurer, not one compounding book value at >15% annually.
What to watch
The central disconfirmer is that rate pressure in property catastrophe reinsurance (-10%/-20% in January 2026) extends and deepens into 2027-2028, compressing the consolidated combined ratio below the 85-90% band assumed in the base case, and that the buyback pace moderates if Bermuda regulatory capital is tightened.
