Warnings

⚠ Traditional cash flow models don't work well for banks — lending activity distorts how much cash the business actually generates.

⚠ Common valuation shortcuts don't apply here — for banks, interest payments are a core business cost, not overhead.

Key Risks

Book value quality matters as much as level — check loan loss reserves
Interest rate sensitivity creates non-linear earnings surprises
Insurance reserving is actuarial, not financial — errors emerge slowly
