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.

ℹ Dividend-based valuation: $2890.53 (952% above our primary estimate). Large gaps suggest the dividend may not fully reflect the company's value.

ℹ Wall Street's average price target is $408.71 (from 38 analysts). Our estimate is 33% below the consensus -- consider that gap carefully.

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
